Recently transferred to Taro and Makoto's school from Tokyo, he tries to make friends with both due to an interest in investigating the kidnapping incident. While he was initially ignored by both, they eventually warmed up to him, with the three of them beginning to try to find the circumstances behind the kidnapping incident and the reason behind their O.B.Es. He tends to be very confident, and initially somewhat arrogant and rude. He has had a fear of heights ever since he bullied someone to suicide by jumping off the school roof, and the victim left a message on the blackboard cursing Masayuki. Masayuki unashamedly admits he ran away due to the message. Instead of feeling guilt he is angry at the student for making him a murderer, a fact he can't get out of his conscience. He is, however, very determined to overcome this problem and tries extensively, including standing on the edge of the school roof, to cure his fear of heights. During his spare time, he often plays his head-mounted display virtual reality game. His father is a researcher at Japan Bio-Tech, while his mother appears to spend large amounts of time playing console games, primarily Tetris or something similar. Of the two other boys, Masayuki has a friendlier relationship with Taro, visiting him in hospital and joking with him. Recently, during a joint experience of O.B.E. with Makoto and Taro, Masayuki displayed the ability to evoke the same weaponry from his virtual reality video game in his spirit form, and used it to apparently destroy the spirit of Taro's former kidnapper. After the incident, he begins to have a little more confidence, finally deciding to intervene in the bullying of one of his classmates. He is always the one who is spying on Reika because he found out about her relationship with his father.
