Okay, so Gaia said that once I have roused my mana, probably as much as I can, I should concentrate on the overall state of my body. Does that mean like viewing my entire body in my thoughts? Or does it mean that I should concentrate on the form of my body, the one it currently has?

Let's just try both of them. So first is rousing my mana.

That means that I will have to concentrate on my mana again. This time around, I manage to separate a chunk of my mana quite quickly. However, it still took around 30s. After that, I imagined looking at my body from a 3rd person view.

I waited a bit and tried playing around with both of my mana or imagining myself from a different angle, however, nothing happened. In the end, I couldn't keep my concentration on my mana anymore and the chunk returned to the main chunk at my heart.

So that isn't how you do it. That leaves the 2nd method as the most probable.

So again, take a chunk of my mana and this time I concentrated on the form of my body as a whole.

Immediately, I noticed what was different. I just suddenly received knowledge about how to change my form from nowhere. That was probably the system helping me.

According to the knowledge, I had to move my mana and infuse it into my body as a whole without any intent. If I were to give my mana an intent of some kind then it would try to accomplish just that. That is also how body strengthening works. If I infuse mana without any intent however then it would activate my innate racial magic which enables the change in the first place.

...

I already tried for maybe a minute but I still wasn't able to infuse mana in the entirety of my body. I always only managed to infuse some parts with my mana. When I then try to infuse the parts that don't have any mana infused yet, I would always lose control over the mana in the already infused parts and it would return to the main mana chunk. Which was really frustrating. Luckily this wasn't nearly as exhausting as learning how to control my mana.

1 minute later I finally managed to get my whole body infused with my mana. Now 2 images of me appeared in my mind.

The first image was of the current me without any carapace other than the small parts on my cheeks and neck. I still had the tail though. The second image was me nearly completely covered in the carapace. The carapace covered my entire legs and arms. However, it looked like my limbs have swollen a bit and my arms have become longer. They reached down til my knees. The claws on both my feet and hands were also longer. My limbs are thicker probably because the carapace is thicker in that form. My back was also covered in carapace plates and along my spine white spikes protrude. My sides had some carapace plates so that I could still bend my body properly. My hair now also looked a bit strange. It resembled the hair that Kerrigan had after being turned into the Queen of the Blades but still remained deep black.

That form really looks like some real monster. I am quite lucky that this wasn't the form I had when I awakened. I quickly concentrated on the first image. After consolidating the image in my mind I felt that the mana in my entire body reacted.I don't know what it did or how it did it, I also had no capabilities to try and figure it out.

I was too busy screaming as my whole body felt like it was sliced up and burned at the same time.

POV Maria

I was currently thinking about what I should teach Mark today. Since he turned into a girl there are many things that he now needed to know. I already explained the importance of a bra and showed him, her how to do it but she currently still refuses to wear one. Next would probably be periods and your appearance. I still can't believe that he spent nearly the entire first day in nothing but his T-shirt.

Suddenly, I was interrupted by a high pitched, gut-wrenching scream that could be heard throughout the entire house. 

Immediately, I sprang up from my bed and ran to Mark's room where the scream seemed to originate from. 

I hastily opened the door and entered the room. I gasped in surprise. I saw Mark thrash about on his bed. He wildly punched and kicked out and even clawed at his own skin, while it ripped open or fell off. He bled purple blood from both his eyes and nose. His tail wildly hit both the wall and the bed. The carapace on his limbs burst open, revealing the muscles beneath and with it the purple blood.

"MARK, MARK!!! What is going on?"

I tried to restrain his arms so that he would stop clawing at his own skin and rip it open even further, however it seemed that her strength was just too great. While I was able to grab his arms, I wasn't able to do anything other than that. I immediately lost my grip on them as he moved about.

If you stumble upon this narrative on Amazon, be aware that it has been stolen from Royal Road. Please report it.

When I tried to grab them and try again, Marks' tail hit me is the chest and threw me against the chair that stood in his room. 

Luckily, it didn't hit me with the spear like a tip but the impact still made me unable to breathe properly and felt like it broke some ribs. Thanks to my vitality, however, I knew that I didn't break any

"Gasp... Gasp"

I tried to get some air in my lungs but it seemed like it wasn't possible for now. 

While trying to regain my breathing, I could only watch as Mark continued to bleed and loose skin and carapace. And while I at first thought that something bad was happening, I noticed that everywhere where wounds came into existence, a patch of fresh skin would quickly take its place. 

Dammit, if only either father or even Jonas would be here. 

Both of them went to the supermarket to buy stuff so Mark and I were currently alone.

By the time I managed to breathe normally again, there were only small patches of the carapace remaining. Only the claws were still whole. In the next moment, however, they just fell off. The resulting wounds bled heavily for a few seconds before stopping. After that, bones sprouted from the mutilated hands and quickly reached an appropriate length. Next were flesh, veins, and tendons. They all grew within seconds before forming normal fingers and thumbs. At last, nails grew. The same thing happened to Mark's toes as well. 

With the fully regrow fingers and toes, the last patch of skin and carapace fell off and were again covered with fresh skin. Mark also finally stopped screaming and fell unconsciousness on his bed.

Mark started screaming only a few minutes ago and yet she already returned to normal. 

The bed looked like some person tried itself on butchering without any kind of instructions. Blood was everywhere and patches of skin and carapace as well. Accompanied by his claws that fell of, it truly looked gruesome.

I barely managed to contain my nausea and struggled with myself to even approach the bed. 

Marks now looked like some normal girl. A beautiful and very cute young girl. The only, still strange features were her tail and the pointed ears. Both of these remained from her previous appearance. A new addition was her nails though. They were not only slightly longer, they also resembled claws a bit and were pitch black. 

Marks was still covered in his own blood and some fallen of skin that clung to him. The clothes were drenched and destroyed, just like the bed. I doubt that you can still sleep in that. 

I quickly wrote my father a message that something happened to Mark and that he is now unconscious. After that, I started preparing a bath so that I could wash Mark. 

When the bath was ready, I picked her up from her bed and carried her into the bathroom.

I let her sink into the bathtub and started washing off all the blood and the remaining skin that clung to her body.

"Really, just what did you do this time?"

First, she changes gender and now this. Didn't you already have enough changes for one week?

Naturally, there was no answer. So I just continued washing if the blood.

It took some time but I finally finished bathing Mark. Her hair was also drenched with her own blood so I had to wash it as well. 

After drying her, I carried her into my own room and laid her down on my bed. With her current body, she didn't weight a lot so it was an easy thing to do.

POV Mark

"Nh..."

As I woke up, I immediately noticed that my entire body felt sore. 

When I opened my eyes, I noticed that I was no longer in my own bed. I looked around and saw Maria sitting at her desk and looking at me.

"Are you awake now? You nearly gave me a heart attack when you started screaming like that. Especially with what happened to you. How are you feeling?"

Ahh, I remember now. I was trying to change my form when suddenly my entire body hurt. 

Wait did it even succeed?

I raised my hand so that I could look at it and was glad to see that my hand now looks like the hand of an actual human. I mean sure, the fact the black nails was a bit surprising and also annoying but it was still acceptable.

"So it succeeded."

Finally, I can live like a romal human being again. Well mostly normal. I could still feel my tail so I didn't part with that thing. 

"Ah, I'm sorry Maria. I didn't expect that that would happen. And currently, while my entire body is a bit sore, I am fine otherwise."

"That's good to hear. I was already that some serious problem may have appeared, given how much blood you lost but if it's just some soreness then its okay. By the way, what were you doing that caused that?" 

"I finally learned the mana control skill so I wanted to try and change my form. And as you can see I was successful. Though I didn't expect that changing my form would be like that."

I don't actually remember what happened while I was changing my form but from the way she described it and the way it felt, it should have been quite something. 

"Also how long was I unconsciousness for?"

"Ah not that long. It's only been like what? 2 and a half days."

2 and a half days? How is that not a long time?

----------------------------------------

POV Gaia

Sigh, what's with all these gods? They are nearly completely reliant on their believers in order to something in the mortal world and yet here they are discussing the course the mortal world should take. Even though they should know that the world almost always takes its own course they still pretend like they can control it. 

"Now that the non-human races are still without any strength or foothold in the world, we should try to weaken them as much as possible or even eradicate them."

Oh my god. Should I not say oh me or something? Anyways why can't he just once, even once stop trying to commit genocide on the non-humans? Just because he is the god that made the human race his chosen race.

"I already told you so many times, even before the war that I would not participate nor allow such actions, dear god of light."

Speaking of non-human races, I forgot to tell her that it would be better to try and understand as much as possible of her innate magic before attempting to change forms. Otherwise, it will lead to a lot of pain and a real mess. I just hope that she doesn't have any kind of permanent problem now that she did it so forcefully and without proper knowledge.

Haa I think I am just gonna leave this god alone for now. He is just too annoying.

I still have to make sure that no sudden mana surge happens somewhere on earth.
