Aired on October 3, 2010
Kyosuke Kosaka accidentally finds a magical girl anime DVD containing an adult game with a little-sister theme after encountering his sister Kirino in the hallway. He confronts her about the item, reassuring her that her hobby is not strange and offering his support. That evening, Kirino invites Kyosuke into her room to reveal her hidden stash of erotic games and anime. She explains her preference for little-sister types but cannot articulate how she developed this interest. Lacking anyone else to share her passion with, Kirino asks Kyosuke to play through one of the games to provide an unbiased opinion. Kyosuke agrees to keep her obsession secret from their parents and helps her explore her interests.
