Saizou is Souji's pet piglet—basically a tiny, adorable chaos agent. He's got a temperamental streak, especially when it comes to Tetsunosuke, who bears the brunt of Saizou's constant chasing and mock attacks. But here's the thing: Saizou absolutely adores Souji, and he's noticeably gentler with people who match that calm energy. Yamanami, Ayumu, and Hotaru (the Choshu girl with a thing for Souji) all get the nicer version of the piglet, which kind of says something about Saizou's ability to read people.
