Age: 8

Not much is known about Ryou's personality before his death.

Out of the three children spirits, he is the most aggressive and appears the most. In Corpse Party: Blood Coveredmanga, Corpse Party: Another Child and Corpse Party: Tortured Souls he is seen taunting his victims before killing them. Much like Yuki Kanno, he uses pronouns "Big brother/Big sister" on his victims, as seen in Tortured Souls, where he addresses Yoshiki Kishinuma and Ayumi Shinozaki in such a way.

Ryou's main killing methods include inducing hallucinations on his victims, as seen by the hallucinations Yoshiki sees in Corpse Party (buried alive or having wires cut him in half) while making his victims strangle themselves to death. He also uses scissors and stabs his victims, much like the rest of the spirits.
