The demon dives toward me ready to grab me with his claws. I get this chance to prepare an attack using Mira.

“Razor Flame!” I shout while slashing the air in his direction. Multiple waves of cutting fire go flying towards him.

He takes at least 2 cuts before I see him spin to the right mid-air to dodge the rest. I think he was not expecting to take damage.

He stops his dive and goes back to the ground by falling. There is a lot of things happening around me but I have to hope that nothing will come my way as I have to keep an eye on this foe.

I change weapons, putting Mira on the magic string and picking Yin and Yang.

“Magnet Charge” I say to use a spell to charge both Yin and Yang with different magnet pulls.

I then extend my arms pointing both of them towards the demon who is with his guard up walking slowly towards me.

“Magnet Shot!” I say charging an area in my hand with an equal pull of the sword in hand to make the sword fly with the force of push.

I only throw one sword at a time and I make sure to remove the magnetic field in my hands just as the sword flies near enough the demon.

I then do the same with the other sword.

The demon parries one the swords using the claws in both hands and dodge the other. I guess there is a limit to how much force I can generate without putting myself at risk as I don’t want anything besides the swords to be affected by my spells

“Magnet Charge.” I say again charging one hand at a time to make my swords come back.

This is repeated for a few minutes with both me and the demon running around trying to hit each other.

He is using what he called Demon Arts. It looks just like magic to me, I can defend it just fine using a heat barrier.

More than once people were caught in the middle of our battle. I hit a few humans and demons walking between us. At least my attacks just damage you. If you get hit by that shadow without defending yourself you pretty much get knocked out by what I see.

“You little bitch! How do you have so much mana?” The demon screams to me as we stop for a moment to catch some breath. Good to know that even this one needs air. Shame I can’t use that spell here or I will kill a lot of people including myself. I am defenseless using that spell.

“I am gonna be honest with you. I have no idea.” I shout to him while changing my weapons, picking Mira again. Yin and Yang can deal damage to him but they can’t take a hit like Mira so I can’t use them in close combat right now. “Thanks for the help.”

“ “ They say back.

He looks really pissed. His body starts to move faster, looking like black flames. His hands grow as big as his head generating claws the size of nodachis. He does something behind his back that launches him straight to me in less than a second.

As his claws swing towards me I block one using Mira and expect my barrier to block the other but he cuts the barrier scratching my left arm a little.

I am taken by surprise and in my panic I try to fly backwards using Mira as a shield in front of me but he stabs me on the sides again before I can fly.

As soon as I move a meter away from him I put a healing fire around me that begins to close my wounds. It hurts like hell but there is nothing I can do.

The barrier is not usable anymore, so I will either have to tank and heal or not get hit.

The demon flies towards me again.

This time I don’t block, I go for an exchange. As he claw goes toward my chest I begin a diagonal downwards slash from my right to left aiming for his head. I create thrusters in Mira to make the slash go faster.

He changes direction as soon as he can make his attack hit kidneys and I just hit his shoulder before he is sent flying to the sides.

I take a second to let my spell heal myself and run towards him as he gets his footing again.

I make a downward vertical slash to try to cut his head open but he blocks with both of his claws. I use the chance to kick him but it does nothing. I guess I don’t have the natural strength to cause damage with just my body.

He puts some force on his claws making me fall back a little and tries to slash me from both sides at the same time with a vertical slash, sandwiching me between his hands.

I fall on my back as if I was playing limbo to dodge his claws. Then I use thrusters to get back up and deliver a blow using Mira. In this position I can’t slash him but I can hit him.

As he feels the hit a little I try to slash his head again. He blocks with one of his hands where I cut his palm a little. I even see some blood.

“AHHHH!” he screams in rage.

He starts to emanate a powerful aura. As I look around both demons and humans are falling to the ground without apparent reason.

As I look at the demon he vanishes like smoke into the air.

“I am going to destroy you.” I hear his creepy voice from everywhere around me. Then something slashes my back. It’s not deep but hurts.

I fly full speed away from the city but cuts keep appearing around my body. If not for the healing fire I would be dead. Also the cuts only appear in my skin, ignoring my clothes.

A few seconds later as I am away from where I was, a powerful slash hits my back again making me fall to the ground. If i wasn’t close to the ground I would be really hurt.

“Are you feeling pain? Don’t worry, there is more to come.” His creepy voice echoes again.

I begin to slash everywhere but a cut aways appears somewhere in my body. The cuts appear faster than I can heal them.

“Fuck you! Inferno!” I shout while stabbing mira on the ground and making my mana pass through here for the spell to activate.

An area around me is engulfed in fire for a few seconds giving my healing fire the chance to heal the cuts enough to not be fatal later.

As the fire stops I see the figure of the demon appear a few meters away from me.

He looks the way he was when the bishop summoned him.

“Very clever, but that will not be enough to kill me.” He says taunting me.

I don’t have the time to answer everything he says to me so I just put my guard up again. This will be a fight to see who can endure more. If I just attack him I won’t be able to deal enough damage to him. I have to strike when he is not defending.

He grows his big hands with the claws again and runs towards me.

I set Mira ablaze and the fight restarts.

He is just a little slower but still fast. If I parry or guard his slash with mira he just uses the other hand to cut me and if I try to attack him he is fast enough to be able to block with his claws or dodge.

I am using thrusters to dodge lethal blows moving my head or chest out of the way of any hit that would kill me.

At this point I lose myself in the battle. I can’t tell how much time is passing as I am in what you would call The Zone. I have nothing on my mind besides this fight. I can’t hear or see anything around me besides the demon.

He is going to stab my left shoulder using his left hand. I create a thruster on it while using my left hand as the main hand for Mira making my body go back a little. When his stab misses I swing Mira at him, going for his shoulders.

He tries to slash my right side but the impact of my bash makes his slash not go deep on my right arm.

The healing fire begins to do his job and I use thrusters on Mira to hastily bash him again. This time he blocks with his right claw just in the nick of time. This makes him fall back a little. I use this opportunity to change back to have my right hand being my main hand as I run towards him.

He then crouches down and tries to slash my legs with his right hand as I get near him. I jump, dodging the slash, but then he starts an upward slash using his left hand.

I use Mira to block the slash but the force of the slash sends my up more than I was expecting.

The demon takes this opportunity and pushes me up as high as he can. I think in just a few moments we are both at least 1 Km in the air.

He clearly has more experience in the air than I have. He flies backwards making some distance between us. I create various thrusters to keep me in the air. At this point trying to get back to the ground would be too dangerous and give him the opportunity to just pull me back up again.

As he begins to charge me I do the same and prepare to slash him but in the last moment he dodges and cuts my face a little. I can fly but I can’t move the way I want just yet. He can move freely.

He circles me going for a dive. I try to hit him again as he gets near me but in the last moment, again, he dodges and cuts me in the arm this time.

This continues for a while but as he is doing his next dive I have an idea.

I put my arms close to my chest holding Mira horizontally and begin to spin. I then start to pour mana into a spell creating a tornado of fire around me. Spinning does nothing to me so I spin as fast as I can to increase the power of the spell.

“Ah!” I hear someone scream as the flames spin around me.

After a few seconds, I think, I stop the spell and see the demon burned a few meters away from me.

“That hurt. But you should be out of mana now.” He says in a confident voice.

This book was originally published on Royal Road. Check it out there for the real experience.

In fact I have no idea how much mana I have right now, so he can be right.

Using the situation at hand I have an idea. I fly stright towards him and make him lock hands on Mira while I push foward.

“You will never be stronger than me in the air.”

Which is true but that was not the objective. Now we are close and he can’t dodge.

“Flame Saw!” I shout in front of him. Various thrusters appear around my body and I begin to spin forward like a saw as I am close to him. With the fire on Mira I really become a flame saw. His claws are sturdy so the limit of what I can do is go with him to the ground where just before we hit the ground I have to stop the spell or I would have a lot of broken bones.

I take this moment to get some air as he is in a crater made from the impact of him falling.

A few moments later he jumps out.

“You will never defeat me.” He says confident but I can see that he took some damage even if it doesn’t show. His body expression is not of someone who is ok. His breath is also heavy, like mine.

I can’t say I didn’t hit him but I wasn’t able to get a clean hit this entire time. Worse yet is that if not for the healing I would have died a long time ago.

I put my guard up again but something happens. All my power is just gone. I can’t feel my mana anymore, my healing fire stops and my hair goes back to blue.

“Fuck!” I say without thinking.

“HAHAHAHA, finally.” He says while walking towards me.

I don’t have the strength to even move now. I am just standing, unable to move.

He gets close to me and with his hands now the normal size he holds my face.

“Maybe I should make you a hostage. We can have some fun while we black mail your parents.” He says in a really creepy tone.

At this point I realize how fucked I am. In my head a million ideas begin to form and the same amount are rejected as I have no mana or strenght to really move. Then something hits me. Maybe I can use those demon arts that this demon used. They are not magic as they don’t use mana, at least not in a way I can detect and looks like every demon can use it. Now that I stopped everything I saw in the battlefield begins to flood my mind. Lots of demons doing various different things or changing into more monstrous forms. Maybe every sub-race of a demon has a different demon art. The fact that I gain energy from sexual pleasure may have something to do with it. It is my best shot.

Using everything I learned in my past life and in this one I will move with the assumption that both my demons parents were a succubus and an incubus as everything related to my uncontrolable urges are sexuall and these are the only two demons I can think that would be of that nature.

The demon is holding me really close to his face. I lean for a kiss and begin to give him a really passionate one. I want to throw up every moment I have a taste of this thing's mouth but I endure. He for some reason is just going with it.

I begin to visualise me absorbing his mana, his life energy, his sanity, everything I can and it works, for a few seconds before he pushes me away.

“You little whore, trying to suck me up.” He says angry.

But at this point I am good enough. I have at least the strength to move again.

I have no idea how much mana I also have but I will have to make it count.

I spit on the ground and begin to run towards the city. There is no way anyone there can’t deal with this now.

As I do that my mana begins to run again and my hair gets red again.

The demon follows me flying and attacking. I have to throw myself into the ground a lot of time to dodge his attacks. But he still hits me a few times but I ignore the pain and continue to run until I am back at the battlefield that is the walls of the city.

“Attack the big flying thing, Help!” I shout and scream to everyone there and like in the story books Sophia just falls behind me blocking the way of that demon. She is now in full armor, not a battle dress, full plate armor, one made for females as I can identify that it is her but still armor. She barrages the demon with light rays and sword cuts.

“Are you all right?” She asks me.

“Not really.” I answer.

“We are going to end this. Go back with Monica, she is in the gates.” She says before going after the demon again and engaging in a fight with him. As I run towards the gate I see that big man that was with her in full armor as well, a copper one, and a big shield as big as him. He is not using a helmet so I was able to identify him. He is going in the direction of Sophia.

I run towards the gate and see lots of soldiers being carried inside the city to be healed. In the middle of all that I see a maid tending to some soldier with bandages, It’s Monica.

I approach her.

“Monica, I need your help.” I say more or less in a hurry.

“Yes lady Lucia?”

“Come with me.” I say while grabbing her hand and dragging her towards an alley where no one could see us.

“What do you need?” She asks puzzled.

“Do you need mana right now?”

“No…”

I then grab the water bottle she was using to wash the solder and drink it to clean my mouth.

“Tell me when I should stop.”

“What?”

I then begin to kiss her again, but this time I just want mana. I concentrate on just getting mana. After what I think is two minutes she pushes me away out of air.

“That is the limit?” I ask.

“Yes…” She says out of breath.

“What did you…” She tries to ask but at this point I just go start to run outside the city again. I cast a healing fire on myself to heal my injuries a little and go after that demon again.

In the distance between various demons, knights and mages and see rays of light and two people fighting a flying black creature, that probably them.

I run full speed towards the area and see that the fight is going well but like me they can’t pin down this thing to deal a real blow.

“I am here to help.” I shout while approaching them.

The guy is acting as a tank blocking any attacks from the demon and Sophia uses that chance to barrage the demon with spells and rapier attacks. This is not her prefered sword as I saw her use normal one-handed swords in training and hunting but I guess she has her reasons.

The demon is even more dodgy with them than with me, in compensation he is not attacking as much.

They acknowledge my presence and when the demon tries to attack again the guy blocks and both me and Sophia attack together.

She creates light rays from the sky making the demon fall a little and I do an upward slash in this chest that he blocks with one of his hands.

He then flies up again and the holes made by the spell fill up.

“You will never be able to completely damage me.” he says, taunting us.

“This bastard just healed most of the damage. He is clearly getting hurt somehow but not enough to actually kill him.”The guys say to me and Sophia.

“Do you two think you can hold him in place for 2 seconds?”

“Sure, why?” They both ask.

“Just do it, I think I can kill him if I get a clean hit. If you can make him go straight to me without dodging that would also work.”

“Ok.” The guy answers.

They both go towards the demon. He is on the ground when he tries to fly up but Sophia shoots down some light rays and he stays on the ground.

I start to circulate and focus all of my mana into Mira. This will not need to hit him directly, he just needs to not dodge.

As they approach the demon, the guy prepares to bash the demon with his giant shield but the demon jumps and flies up a little to dodge.

Sophia uses the shield as a platform and jumps slashing the wings of the demon making him fall.

The Guy then bashes him in my direction as he falls, before he can regrow his wings.

As the demon gets his footing again, both Sophia and The Guy charges at him again, this time he uses his demon art to shoot projectiles at them that are blocked by the big shield.

Using that opportunity the demon comes straight to me.

Both Sophia and the guy then start to run towards me as well.

Sophia shoots various rays making the only way for the demon to hit me is to hit me straight from the front.

As the demon gets near me I get ready to slash this piece of shit with all my strength. Sophia and the Guy for some reason get faster and reach me along with the demon, one on each side.

As I begin to slash downwards the demon stabs me with his normal claws in my stomach but I don’t falter, I continue, he is just where I want.

“Excaliburn!” I shout while swinging mira downwards.

Mira is completely on fire and as I hit him what I can only describe as a wave of fire appears from the sword burning everything in its path in a cone in front of me.

Before I fall to the ground I see that only the hands of the demon remain and Sophia makes sure to remove them from my stomach and completely destroy it.

My mana is exhausted and my hair goes back to blue.

“Are you alright?” Sophia asks.

“I could use some healing, there are 8 roles in my stomach.”

“Give me a second.”

She then begins to heal me using a really bad healing spell. It takes a few minutes for the holes to close. During this time I begin to talk with them.

“Hey, big guy. What is your name?”

“Drex, nice to meet you again.”

“Thanks for the help.”

“We would have come sooner but we had to take care of another general on the way here.” Sophia explains.

“General?” I ask.

“If you look around you will see that the demons are fleeing. Without leadership they usually run away.”

I tilt my head a little and a lot of demons that are still alive are indeed running away.

Then we hear a big explosion coming from the city. As we look we see that one the other gates exploded.

“I guess it is over then.” Drex says.

“Why?” I ask, confused, as I get up.

“That powerful elf mage was going there, I don’t think anything can survive that.”

I have to agree. For a second I felt more mana than I used on that last attack.

“Drex I am going to take her back to the city, go help the clean up.” Sophia says.

“Ok, see you later.”

Drex runs off towards the few people still fighting and Sophia begins to walk with me towards the city while holding me so I don’t fall to the ground as I am somewhat weak right now.

“So, who is him?”

“Who?”

“Drex.”

“You could say he is my fiance.”

I am taken by surprise.

“I didn’t know you were going to marry.”

“I don’t have my hopes up. He should probably just marry someone else instead of waiting for me.”

I can think of a few reasons why she thinks this way.

“Do you like him?”

“Of course I like him, but we can’t be a family.”

I stop.

“Sophia!”

“What?”

“You are going to go back to that man right now and drag him somewhere where you two can marry right now or I will.” I say in the most serious tone I can.

“This is not the time for this.”

“I will fight you if I need to.”

“You can’t even walk.”

“That makes no difference.”

Sophia removes her helmet and her expression is more of someone who is annoyed than someone who is angry or sad.

“Ok, you get one punch.”

I then muster all of my strength and punch her face with my right hand but it does nothing. It goes so slow that a child would be able to dodge that. I am really out of energy right now.

“Ok, my turn.” She says.

I feel a punch in my gut and I am knocked out.
