Mizuki, Yusuke

水城祐介

Yusuke is a high school student orphaned and forced to fend for himself. One day, running late for class, he is compelled to take a shortcut to arrive on time. During his journey, a silver bracelet strikes him on the head, causing him to stop. When he looks up, he sees a young girl descending from the sky directly toward him. The girl remembers only her name, Rouge, but suffers from amnesia regarding everything else.
Acting out of goodwill, Yusuke takes the unfortunate girl to his apartment. After getting to know each other, he promises to help her recover her lost memories (and allows her to stay with him for as long as necessary). Yusuke quickly falls for the girl’s innocent and naive charm, striving to be a gentleman and a caring person toward Rouge.
It is also worth noting that Yusuke has a habit of exclaiming, "Oh Mother, Oh Father in Heaven!" when things go terribly wrong.
