Tokio Oshima

Tokio is a stereotypical teenage boy, who plays video games and is addicted to fast food. He is greatly concerned with Juna's safety, and tries to protect her, not realizing he is powerless against the force she is trying to fight. He considers himself in love with her, but has a distorted view of what love is. Despite never having even kissed his supposed girlfriend, he attempts to both propose to her, and later have sex with her, neither successfully. Though he sees what Juna is doing, he understands her purpose even less than she does, and is quick to criticize her actions as needlessly obsessive.

In his confusion, he ends up leading on their mutual friend, Saiyuri, leaving an uncomfortable love triangle.
