LIP! Lewd Idol Project Vol. 3

Kanako is a tough and temperamental rocker girl, leader of a troublesome gang in Akihabara and bassist of her own band. She's also a little bit tsundere, but... Don't you dare say that to her face! Ranko sees in this girl the potential to be the third member of the group of lewd idols. Her attitude, charisma, and popularity among her people makes Kanako the perfect candidate to give the group that touch of aggression that is lacking, in order to gain the attention of a new type of audience attracted to bad girls. But... It is impossible that a girl like her would want to join a group of idols(Storyline via IGDB)
