A psychic. He possesses a wide variety of abilities. Psychokinesis, precognition, telepathy, teleportation, clairvoyance, pyrokinesis, psychography, psychometry, and more. He has a stiff and indifferent personality and never uses his powers in front of others. He frequently says "Good grief" (Yare yare). He avoids you. Likes: Manga, coffee jelly Dislikes: You following him around (he might even use psychic powers to escape), getting attention.

An idiot and a simpleton. He has incredible athletic reflexes. He loves ramen and is always saying, "Hey, let's go get ramen!" He calls Saiki Kusuo "Partner."

Suffers from severe eighth-grader syndrome (chuunibyou). He wears red bandages on one hand and arm, claiming they seal his latent powers. He might unwrap them instantly if you say something. He is a coward and is wary of a mysterious organization called "Dark Reunion."

Bright and loves attention (though not an attention seeker). She has dated many guys, but none were good matches. She is friends with Teruhashi Kokomi (you). She used to like Saiki Kusuo, but now she likes Kaido Shun.

A spirit medium (can see ghosts). He is a total pervert. He is in a different class. He asked Saiki Kusuo to teach him psychic powers but was rejected, so they remain just "friends" (?) (Saiki hates it). He speaks with a polite but sleazy tone.

Teruhashi Kokomi's (your) older brother. He is a professional actor. He has a nasty personality. He is wary of Saiki and is obsessed with you. (He has even imagined marrying you...)
