Souji Kushiki
Second son of the prestigious Kushiki family. Left home in middle school to go to an all-boy school, thus why occasionally being teased as "gay" by Sasai. Recently return to his hometown when serial murder cases targetting his school's students are occuring. Handsome, excels academically as well as athletically. Always put on a stoic expression. Target of romantic affection from his three sisters: Youko, Saki and Harumi. Seems to have a supernaturally connection to Youko as shown on how he can feel her presence whenever she is close by. Indifferent to Youko's obsessive sexual harassments, but seems to boldly accept Saki's advances.
