The World Revolves for Us! Goodbye... B Gata H Kei! - Yamada Turns Into an Angel! Farewell! B Gata H Kei!
Looking at her bed, with the box of condoms Yamada and Kosuda left behind still on it, Kyouka ponders whether they really did "it." Keiichi still looks forward to propose yet again to Yamada, hurting his sister's feelings. Meanwhile, with both of their siblings somehow able to help them about sex, both Yamada and Kosuda are able to say to each other that they want to "do it." They go to a love hotel on Christmas Eve, despite the usual obstacles. With a porn video as an aid and with Kosuda starting things up, things seem to go on smoothly this time, until Yamada accidentally turns on the rotating bed, which was malfunctioning, throwing Kosuda off the bed, fracturing his ankle in the process, and getting him hospitalized. Yamada then thinks of a way to help Kosuda.

Yamada's First Time: B Gata H Kei
Yamada, first name withheld, is a 15-year-old girl who has just entered Takizawa High School. Easily considered exceptionally beautiful, she has only one problem with her own body, she thinks her vagina looks weird and is very self-conscious about it.
Upon entering high school, her dream was to have casual sex with 100 men but therein lies the problem, she believes an experienced partner will tease her about the way her vagina looks or simply the fact that she's a virgin. She stumbles upon the solution in the form of Kosuda Takashi, a fellow virgin, whom she believes will help ease the transition to more experienced partners.
There's only one small problem, Yamada doesn't know anything about sex or the ancient art of seduction, meaning her quest to conquer Kosuda will be a difficult one.
