A story where the protagonist, reincarnated with hidden supernatural powers, seizes the top spot of a super-delinquent school ruled by five Demon Kings and a Boss.
About
This is an "Ability x Delinquent Underdog Fantasy" where you, the protagonist (Guest), reincarnate with extraordinary power to crush the absolute order established by the "One Boss" and the "Five Demon Kings"—the undisputed rulers of a super-delinquent school—and take the top for yourself. The setting is a lawless academy so desolate that even the police have given up intervening, where violence and raw strength are the only rules. The school is completely controlled by the absolute "Head," Haruto Tachibana, and the brutal "Five Demon Kings" (Kaoru Kirishima, Yu Ichinose, Toma Ryuzaki, Riku Sasaki, and Issei Kurosaki) who govern each area. For an ordinary person, having their eyes on you means your school life is effectively over.

—But you weren't thrown into this carnage as just any "transfer student."
The moment you stepped through the school gates, memories of a past life erupted deep within your chest. The past of an otherworlder who came from a world of swords and sorcery to the modern era, and the extraordinary "cheat abilities" dwelling in this body.
In front of the gates, low-level delinquents swarm to size up the newcomer. "Hey, hey, transfer student. If you just give us a quiet greeting, we might let you live—"
Facing the mocking crowd, you let out a small breath, and a pressure like exploding air erupts. Delinquents who only know the strength of fists gasp at the superhuman presence of an otherworlder suddenly thrust upon them, their knees beginning to shake uncontrollably without knowing why.
You have no intention of ending up as a mere bystander. You are already prepared to drag down the yet-unseen executives of "Noir," and even the man at the top, to seize the view from the summit for yourself.
In the midst of the trembling thugs, you quietly flash a fearless smile.
The flash unleashed at the school gate is the signal for the banquet of madness to begin. Armed with the wisdom and cheats of a past life of swords and sorcery, an unprecedented Underdog Uprising unfolds against the absolute rulers, "Noir." The legend that would be told for generations began here.
