Description
Tooru Oshikiri is a high school student who serves as one of the central characters in the anime Junji Ito Collection. He appears throughout a group of stories focused on his unsettling encounters with the supernatural, events that are often hard to tell apart from hallucinations.

His background is marked by isolation. He is a quiet boy of short stature with very few friends, and because his parents work abroad, he lives alone in a large mansion. This solitude deepens his loneliness and gradually affects his hold on reality. He has a dour personality and a short temper, and he is especially sensitive about his height, which adds to his defensiveness and social withdrawal.

Oshikiri's motivation is largely a search for stability. Rather than seeking out the strange, he is someone whom strange events seem to follow. Throughout his story arc, he tries to make sense of, endure, and escape the bizarre phenomena that surround him, ranging from visions of long-necked figures to a haunted bog rumored to trap its victims, a strange girl with unusual pen pals, and the disturbing secrets inside his own house.

In the story, he acts as the protagonist through whose perspective these events unfold. Each episode places him in a different eerie situation, and his role is that of an ordinary person caught in extraordinary circumstances. Those he becomes close to also tend to be drawn into the strangeness. In one segment he brings a friend named Mio to his home but refuses to let her inside, claiming the house contains a portal to another dimension where his and Mio's doubles live. Mio believes he made this up to keep people at a distance, which highlights how guarded and closed off he is.

Over the course of his appearances, Oshikiri develops mostly through the erosion of his normal life. His loneliness and distrust grow alongside the mounting strangeness, and he frequently cannot be certain whether what he experiences is real or imagined. His defining characteristic is not a supernatural power but the fact that inexplicable events seem to gravitate toward him and those he knows. His connection to the dimensional portal within his home makes him especially vulnerable to forces beyond ordinary understanding, and he exists on the boundary between the everyday world and something far more disturbing.
