31 parts Complete MatureYaku x femreader
You are Lev's older sister, Haiba Y/n. Lev manages to convince you to become the manager for the boys' volleyball club at Nekoma.
Yaku is immediately infatuated with you, despite who your brother is. To the libero, you take more after your older sister, Alisa.
Lev is clueless to his senpai's feelings, but worries when he hears you might have a thing for the third year libero.
Boy, is this gonna be an interesting year.
Warnings: strong language, slight violence (Yaku hitting his teammates), sexual content (sorry guys, I got horny while writing)
