Katai Tayama

Katai Tayama 田山 花袋 (Tayama Katai) is an information broker 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.

Background
10 years ago, Katai and Kunikida met. According to Kunikida, when Katai was dragged out of his room to join the Agency, he laid out a futon in his office and began living there and even locked himself in his room to avoid going out.

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.

Katai makes a brief cameo in Chapter 48.5 when it is revealed that the Agency asked him for help regarding the mastermind.

In Chapter 49 Katai is seen researching the Rats in the House of the Dead, when Fyodor Dostoyevsky suddenly comes up behind him and shoots him.

In Chapter 50, Katai leaves behind a hint of evidence to tell Kunikida that he is safe. He later shows up with Natsume and he reveals that Katai has discovered the base of the Rats.
