Riku Soma is one of the male students at Akademi High School.
Riku has purple hair that spikes to his right. His eyes are red. He wears the default uniform unless customized. He will also come to school in different outfits and different appearances if you tell him what Kokona is attracted to.
Riku is a Social Butterfly. He will strike a cute pose if a camera is pointed at him. If he witnesses murder, he will run to a heavily populated area and call the police.
Riku has a crush on Kokona. You can match-make them in-game in the current build of Yandere Simulator.
