A medical personnel from [[Lee (Arknights)|]]'s Detective Agency, he was a well-known underground doctor operating in the gray zones of Lungmen. After joining, he proved to be a tremendous wellspring of medical knowledge and theory with the clinical experience to back it up, though his style of practice is rather worrying. However, based upon [[Kal'tsit (Arknights)|Kal'tsit's]] comprehensive evaluation, he was recommended on a provisional basis to the medical equipment department and technological development team.

Does not get along well with Rhodes Island operators, with notable exceptions such as [[Hung (Arknights)|]] and [[Waai Fu (Arknights)|]], who are his agency colleagues, and [[Warfarin (Arknights)|]], who regularly gets into discussions with her regarding medicine.

Infamous among the player base for dealing massive friendly fire damage in exchange for immense power boosts.

His motif is based on the [[komainu]]. His [[voice actor]] is [[Sanpei Yuuko]].
