Ritsuka likes to take photos for memories. He has a fear of forgetting certain things. He tends to take pictures of objects and nature instead of people. He seems to be a trouble child. He was once an out going person until his brother was announced dead and then became reclusive. His mother often beats him due to this and says he is not the real Ritsuka. He has a strong connection to Soubi, especially since Soubi was good friends with his brother. He once idolized Seimei.
