A photographer who frequently visits the village of Hinamizawa (especially during the Watangashi Festival).

Spoiler

In every arc, he ends up being the killed victim of Oyashiro-sama's curses on the night of the Festival. During the Festival, he is still alive and looking happy but his manner of death shows that he tore at his own throat with his own fingers. The baffled police autopsies seemingly results with his body having no trace of drugs having been injected to cause him to do such an act of madness. He also has a good partnership with Takano Miyo (who is also a 'victim' of the yearly curses). It is revealed in Kai that he has affections for Takano and she plays along with his attraction for her. He falsely laughs when he tries to avoid a question or is told a foreboding prophecy about himself but looks willing to help Takano to discover the mystery of Oyashiro-sama's curses.

Not much else is known about his personality.
