"A World Only Hair Knows"
In an effort to help Rentaro, who lost his hair and eyebrows due to his overwhelming love for his girlfriends, Kusuri Yakuzen develops a hair growth formula. Inspired by this, Hahari Hanazono suggests a hairstyle change for the girls, allowing the Rentaro family to enjoy new looks.

However, things take a chaotic turn when Hahari takes another experimental drug, causing her hair to go berserk! Acting on its own instincts, her hair rapidly grows out of control, extending beyond the school grounds and attacking people throughout town.

Can Rentaro and the girls escape this hairy situation unscathed!?
