Bottom-Tier Character Tomozaki

弱キャラ友崎くん

Yuuki Yaku's light novel opens the story of Fumiya Tomozaki, self-declared bottom-tier at real life but ranked first in the fighting game Attack Families, until he meets the game's second-best player face-to-face. She turns out to be Aoi Hinami, his blunt, wildly popular classmate, who is convinced life runs on learnable rules just like any other game and recruits Tomozaki as proof. This is the original novel behind the manga and anime adaptations.
