Tsubaki's hobby is making original T-shirt designs, but when his fellow Student Council members proclaim them "lame", he goes to his twin brother Bossun for a shot of creative advice. Later, Switch and Bossun are evenly matched in their quiz challenge on a popular mecha anime show, Code A: Chian's Counterattack, so Switch invites Bossun to an otaku meet-up to see who is best between him and Switch. But when Switch doesn't show up texting he has a cold, will Bossun be able to fit in and prove himself?
