Kyoukai Senjou no Horizon – Girls Talk - Volume 1, Chapter 5: Attack and Sweep

Brutality is my style of conduct! If you can't accept that, I'm ready to fight—that's who I am!Don't mess with me, otherwise, I won't mind teaching you the meaning of “The Return of the King”!!!

I transmigrated as the hidden mastermind who betrays everyone at the story’s end.Since I wasn’t particularly interested in the destruction of the world, I was just leisurely waiting for the ending…“You are the only one who has ever seen my drawing of a boa constrictor properly.”“When I make plans to meet you at 4, my heart starts racing from 3… Is this what it means to be tamed?”For some reason, the heroines keep showing interest in me.

A hero must be compassionate, selfless and courageous.But that isn't all. Because a hero must also be powerful.In this world, power is everything. Strength decides who gets to save lives and who's left with community service. That’s why I was nothing — a rank 50 E-Class reject, skating through the streets, saving what little I could while the real heroes battled gods and monsters.Then one day, I died. Almost.Dragged into the abyss, I was given a second chance: the Forever Core. An armor that evolves. A system that never stops adapting. Every battle, every hit, every mistake, I come back stronger.Now, the monsters that once crushed me can’t kill me the same way twice.I must adapt. Evolve. I must grow stronger and fight harder. Because humanity is worth fighting for.Even if I have to burn every villain alive to prove it.

A cultivation story about how a declining sect is restored by a narcissist, a troublemaker, a meanie, an idiot, and a wimpy kid.
