"But don't worry Gil, I promise I'll call and visit you. You can come visit me too," says Lavinia with a big contagious smile before taking my hand and starting to run around the house.

Every now and then Sebas looked at his young master with narrowed eyes.

Some hours later.

It's been a while since I talked to Lavinia.

After that we spent the whole afternoon playing.

I was really sad that I couldn't help Lavinia, and I promised myself that I will protect all the people precious to me, even if I have to fight all the Factions in the world.

After we played around for a bit, an old woman came to pick up Lavinia, and she kept staring at me like she wanted to see my soul.

Or she suspected my [Sacred Gear] which is not impossible, after all this woman, Glenda, only rescued Lavinia so she could research her Sacred Gear.

The scariest thing was that Sebas was also staring at her deathly, he was one step away from killing someone.

Well now it's been a while since Lavinia left, and I decided to see how the dungeon worked and so I needed a place to test it, so I decided to go to the basement of the house, although it was difficult to convince Sebas to leave me alone. .

Now I'm in the basement which doesn't really look like one after all this is basically a big room full of toys and old objects that we don't use anymore.

"System how do I activate the dungeon?"

[The host must first select which creature will inhabit the dungeon]

"What are the system options?"

[The options are as follows:

-Devils.

-Angels.

-Fallen angels.

-Dragons.

[More options will be released along the way]

"I see, basically it's the main DxD races"

[Want a Description, host?]

Hmmm, I didn't know it had Description.

"Yes"

[The descriptions are as follows:

-Demons: Demons are one of the three main factions of DxD, alongside angels and fallen angels. Fiends often have a human appearance, although they have black wings on their backs similar to bats. But there are also demons with demonic appearance. All devils have increased physical abilities such as superhuman strength, endurance, with enhanced senses such as increased hearing range and vision. Also, as creatures of the night, demons have the special ability to see clearly in the dark. Demons also have the ability to fly through their bat wings. Demons are also able to use a type of magical power called Demonic Power to perform various feats. Their biggest weaknesses are the Holy Weapons and the Holy Magic of the Angels which is capable of harming them.

This story has been taken without authorization. Report any sightings.

-Angels: The Angels are one of the three DxD factions, alongside the demons and fallen angels. Originating in heaven, angels are powerful beings who serve the biblical God and have the power to inflict pain on demons/demons and, by extension, fallen angels, due to their light-based powers. Angels look similar to humans, except with white feathery wings and a halo positioned directly above their heads. All angels have light-based powers that can cause severe damage to demons and fallen angels and can create numerous light weapons, such as spears, arrows, swords, a whip of light, balls of light and rings of light, which can be used to grab hold or restrain an enemy.

-Fallen Angels: The Fallen Angels are one of the three factions of DxD along with demons and angels. Fallen angels are angels who have fallen from God's grace, due to having "unclean thoughts" that lead them astray from God's teachings in the Bible. The Fallen Angels have an appearance similar to your Angels with their wings; however, their wings are black in color as opposed to the white wings of the Angels. Furthermore, because they were cast out of heaven by God, they also do not have halos above their heads. Though cast out of Heaven, the Fallen Angels retain the ability to create light weapons. This type of weaponry is extremely harmful and poisonous to the devils.

-Dragons: Dragons are one of the most powerful and prominent creatures in the DxD world. Dragons are creatures that represent power. As such, at all ages, Dragons are admired, respected and feared by all. Dragons are beings created from large masses of energy that act freely and selfishly. They have two prominent appearances being the Eastern and Western Dragons. The only major weakness of Dragons are Weapons with Dragon Slayer attribute.

Hmmm I understand now.

And with this description it is also possible to understand the weaknesses of each race.

System what are the levels?

[The available levels are:

-Low class.

-Middle class.

-High class.

-Final / Ultimate class.

-Class Maou / Seraphim / Cadre.

Hmm understand.

And to get out of the dungeon?

[To exit the dungeon, the host must meet one of two requirements:

-Kill the Boss.

-Have less than 100 Hp.

I understand then either I kill the boss to leave or I must have my health below 100.

What is Boss?

[A boss or "boss" also known as a Boss is an enemy that is usually faced at the end of a phase or section of the game and determines ascending to the next level. Since these enemies are generally stronger than those found throughout earlier steps and are one level higher than the host chooses]

So if I choose the middle class dungeon the boss will be upper class.

I understand.

System make a dungeon of middle class demons.

[Yes host]

[Preparing dungeon...]

Slowly I see the space around me dissolve before it starts to change.

The land that used to be full of toys and joyful turns into a great corridor of a medieval castle, the walls and the floor are made of stones, with large torches on the supporting columns that show the way, the cracks in the stones of the castle, on the walls and floor, seem to be made of pure flowing lava.

[Dungeon prepared]

[Good luck host]

Thank you system.

I started walking the halls calmly, I admit this is very scary.

I feel a small shift in the magic of this place thanks to the [Mana Manipulation] skill, and looking forward I see the cause of that.

From the shadows ahead comes a large being, about two meters tall, he was totally black, as if he were made of stones, he also had no face, only two flaming holes from where his eyes should have been, as well as large thorns from its back from which flames came out and big sharp claws, besides having a kind of boot, or part of a piece of armor on its legs.

I can't help but feel a shiver crawl up my back, it's actually a little scary.
