異世界から帰ってきた勇者であるオレが歌舞伎町で王になる話

Synopsis

Yuji Kuze, the hero who once saved another world, returns to Japan only to find himself without a place to belong—reduced to what society calls a "loser." Just as he contemplates ending his life, he wanders into Kabukicho and encounters a peculiar concept café. This café is a special place where girls who are also "otherworld returnees" work. "You should try becoming a hero in this city again," someone tells him—pushing him to stand back up. Thus, Yuji vows to rise once more!
