His birthday is on May 22, his starsign is Gemini and bloodtype AB. Shoei is Mio's closest childhood friend and the scion of a very wealthy family, although Mio initially doesn't recall their past together. His father is the Omori family's landlord. He is popular, athletic, intelligent and handsome, adored by many girls in school, despite his cruel, cold demeanor. He is deeply in love with Mio. He manipulates events so that Mio is first forced to work in his home as a maid, then to live there. Spoiled and extremely wealthy, he lacks in compassion, consideration and empathy towards others. Mio later takes it upon herself to re-educate him to be a better person.
