This is the one you put on when you don't want anything to happen, and that's the entire point. Eight episodes of Yukino and Kanade circling each other in a dorm room, and the send-off is a day at the pool: chlorine, sunlight, and two sisters who already know exactly where they stand. Sakuya still can't help herself around Yukino, and she remains the show's best comic engine precisely because nobody else in the room has that kind of nerve. The reminiscing does the heavy lifting here, memories traded like they're worth more than plot, which for this series they are. Be honest with yourself going in: there's no arc, no revelation, nothing that develops anyone past where episode seven left them. It's a coda for people who got attached to the Sakurai twins and just want fifteen more minutes with them before the lights go out.
Twin sisters Yukino and Kanade Sakurai share a dorm room at their high school, where they spend their days with friends and with each other. Their story has already been shaped by underclassman Sakuya Kamiyama's long admiration for Yukino, which set off the events that led Yukino to tell her sister how she feels. Designated as episode 8 and released with the second DVD volume, this special is the final Candy☆Boy episode and centers on a day spent at the pool, told as a gentle slice-of-life romance.
