Son Toutoi

Toutoi Son is a student in Shouko's class. Despite his looks, he isn't very noble. He's introduced in Chapter 130, where he's forced to introduce himself by telling an embarrassing story. During middle school a girl saw him pick up a porn magazine by the riverside. His next appearance is in Chapter 150 as the MC for the "Summer Uniform Wearing Grand Prix". Somehow he knew that Shouko was wearing 60 denier tights instead of 80. He's seen looking for porn magazines with Ohai and Fukusuki in Chapter 192.
