Classroom of the Elite, Without a System, I Can Only Make Friends

Just by answering a question in a group chat, Jiang Chengshi was sent to the world of Classroom of the Elite and given the identity of a new first-year student at Koudo Ikusei Senior High School. It was his first time reliving his youth and his first time transmigrating. Those should have been two joys coming together, but...why? Why was there no System? He had no memories of this world, and even his household registration had been changed. It seemed his lifeline had become a noose, and after graduation he'd be left to wander the streets of Tokyo. No, he hadn't lost yet! As long as he became close friends with these future pillars of Japan during his three years of high school, then even if he left school with nothing, his friends would surely help him out! Class competition? Don't let it get in the way of my friendships! Personal points? Take them, take them. No need to be shy with your big brother! Special exams? Let's fleece the school together, then go throw a party! Jiang Chengshi: This is my struggle to survive!
