Classroom of the Elite: Black Sphere Academia

Transmigrated into the world of Classroom of the Elite, Chris awakens a daily random item system — a Demon Passport, a Time-Stop Watch, a Memory Eraser... Just as he was settling in to enjoy the chaos of elite students scheming over points, his system rolls a new item: the "Gantz Black Sphere Core." Through its god's-eye view, he discovers the truth lurking beneath the surface: Parasytes hiding among humans, feeding on brains. Ghouls hunting the living in the dead of night. Evil spirits drifting through the old school dormitory... All while the school's elite students keep backstabbing each other over a few thousand points. Chris, now administrator of the Black Sphere, smiles warmly. "Since this is a meritocracy — let's make 'merit' actually mean something." The Black Sphere descends. The game begins. Arisu Sakayanagi, eyes blazing with obsession: "Clear the game and my heart gets cured? Heh. I'll take this little chess match called 'survival.'" Honami Ichinose, hands trembling: "Score 100 points and someone comes back to life... For everyone's sake, I'll keep fighting." Kiyotaka Ayanokoji, slipping back into his bodysuit and eyeing the Sphere with quiet calculation: "Earn enough points to buy your freedom? ...Surprisingly reasonable." Chris just smiles. Looks like I'm still the one ahead. 【Full Control + World Reshaping + Rule Setting + Item System】 — Description from novelcodex.org
