The man who introduces himself as "Shizuka Saihara" is actually a guy. He has a quiet and calm character, and under his feminine fake shell, he hides his dislike and rejection of everyone. He can't stop pretending to be a girl and is terribly afraid that his secret will be revealed. Shuichi does not like new acquaintances and has difficulty getting used to people, but despite the fear, he still strives to be useful to others. He has an easygoing personality and does not like conflicts.
