MTL - Rebirth 1983: Starting From Taking Back the Family Property - Chapter 55 found it

A continuation from where High School DxD Volume 25 left off.

I possessed the weakest character in a survival game. Before the game started, 97% of the viewers bet that I would die. But I am confident. Because I am here, this character will survive until the end. I know the information about this survival game. *** After working hard, I became the guild master of the No. 1 guild and one of the top rankers. I gained reliable comrades and allies. “Rudel, you’re a really good person.” Lilith, the beautiful female character who always trusts me unconditionally. “Let’s eat that deer.” Gio, the battle member who, despite being half-naked and always hungry, holds immense potential. All I did was strive to survive. But some wanted more from me. “If you don’t have anyone else in mind… you could accept me.” The No. 1 male character in appearance clings to me, nearly in tears. The hidden character and the only bug character in this game that I found- “Rudel, you are dazzling. Both in body and soul. Unlike me.” He looked at me with clear eyes as if I were the only person in the world. Everyone, please stop. I’m busy uncovering the secrets of this game.

The world changed the day that cracks appeared in the sky– suddenly monsters named『Demonic Beasts』appeared and began to rampage, attacking people.

Meanwhile, girls called『Magical Girls』began to appear to counter the demonic beasts. As they defeated the demonic beasts, gradually people’s lives gained a semblance of composure.

–but when there is light, there is also darkness.

In the corner of an alleyway, a boy who had been attacked by a demonic beast was dying. His voice begging for help did not reach anyone and his body refused to move.

「Boy. Do you want to be saved?」

Looking into the boy’s face, a black cat began to speak to him.

The boy nodded firmly to the devilishly sweet invitation, in response the black cat mocked him.

「Is that so—then I’ll【Haunt (Save)】you」

—on that day, a『Magical Girl』was born in a place that no-one knew.

『She』never laments, no matter what the future may bring.

I was born into a prestigious martial family, yet I was nothing but a useless person with no talent whatsoever.At least, that was the case until I was trapped in a dream.[You cannot die here.][You can not lose your mind here.][Time does not move in this place.][You cannot leave until you reach the extreme.]Geniuses and fools—people say these are two unchangeable truths of the world.They claimed that I could never enter certain realms because I was a complete fool.But when a human body and soul are thrown into the extremes of time, they adapt.[Congratulations. You have reached the extreme.]Now, it is time to leave.
