Riku Soma is a canon character and a test suitor who attends Akademi High School.
Riku has purple hair that has two loose strands sticking out on his right side. His eyes are purple as well. His uniform is dependent on the player's choice.
If customized to fit Kokona's likings, his purple hair will be slicked back. He will start to wear glasses and will have a piercing on his right ear.
Riku has the Teacher's Pet persona. He will not react to a camera being pointed at his face, as there are no camera animations for male students yet. If he witnesses murder, he will report it to his teacher if another Teacher's Pet hasn't already.
Riku's task is to take a picture of the kitten to see how it is doing. After Ayano does this, he will become her friend.
Riku has a crush on this girl. He is also her suitor. If Ayano does all the steps to matchmake them correctly, the two will enter a romantic relationship.
