Katai Tayama

Katai is a hacker who also serves as an informant for the Armed Detective Company. He used to be a member of the Agency, and has known Kunikida for ten years.

Ability
His ability, Futon (蒲団, Futon), allows him to control any electronics within sight as long as he isn’t touching them. And at a speed that is tens of times faster than normal.

Additionally, it seems that he can only concentrate at wherever his body and mind are most relaxed. He can only activate his ability when he’s wrapped in his futon.

Plot
In Chapter 41, Kunikida and Atsushi visit Katai in order to obtain information. He's supposedly a remarkable hacker that served as an informant for them. But then he is unable to help the Agency right away due to the fact that he is suffering from love-sickness. Katai had fallen in love with a black haired maiden and contracted the Agency to help him confess to her as per Atsushi's suggestion.

It is revealed the woman is Gin, and he is consequently turned down. He is saddened by this, but claims that it is enough for him. With that he gets to work.
