Shirou Honjou

Shirou is Rika's ex-fiancé. He used to keep her photo in a notebook and show it to people, to brag about her beauty. He left his home island 17 years prior to the start of the story, after discovering his family's secret. [Spoiler] Shirou wanders around the clock tower mansion; after being disfigured in a fire, he lost all memories except for the good moments of his life, though he still recognizes Tetsuo. He admits to only getting close to Rika's mother for her financial assets, but falling in love with Rika when he finally met her. [/Spoiler]
