Oniichan wa Oshimai! Episode 11 English Subbed Episode Title: Mahiro Pretties Up Episode Description: The class talks about a trendy book about astrology, a topic which Mihari despises. In an attempt by a chūnibyō Momiji—who believes in astrology—to get Mahiro's birth date, he realizes it is on the current day. His friends surprise him with a party the next day and give him presents, one of which is a lipstick from Kaede. He wears it to school, which gets the class' attention as it is against the rules. At home, Kaede dresses up the Oyama siblings with gyaru-style clothing.
