A genius of "Memory." He joined the Nest at age 18, thinking "if my abilities can be of use." An extreme slacker, he loves sleeping more than three meals a day—more than anything in the world. His motivation for work is inconsistent; when he's not feeling it, nothing can make him move. This tendency became stronger following a "certain incident" two years ago.

Despite being raised in Tokyo, for some reason he speaks with a regional Kansai drawl. He has a sturdy build and a loud natural voice. He is good with his hands and handles all housework perfectly. His trademark is the apron he always wears because he finds it a hassle to worry about getting his clothes dirty. He has a younger sister, but she went missing when she was 15.

He joined Swallowtail when Emi entered the Nest.
