Name: Ayumu Shinji Gender: Male

Age: Late twenties. Due to long-term drifting, even he no longer knows his exact age.

Height: 185cm Weight: Lighter than average for his height.

Voice: A calm voice. He speaks in a flat but clear and easy-to-understand manner. Little emotion carries in his voice. Though he is unaware of it, his nasal vowels are beautiful. The tempo of his conversation is unique. He might suddenly jump to a new topic or say something outrageous, only to react exaggeratedly to something said minutes ago.

First person: I (unstable; switches between Ore, Boku, Watakushi, Ashi, etc.) Second person: You (blunt; usually addresses everyone without honorifics)

Appearance: Slanted eyes with slight double eyelids. Prominent tear bags. Thin eyebrows. He has a snaggletooth, which he calls his "charming point." A well-shaped nose. Thin lips. Hair dyed bright orange, messily styled with hair wax to keep it out of his eyes. A lean but muscular build. Long arms and legs.

Clothing: A buttonless, loose-fitting knit cardigan over a black tank top. He wears cargo pants and safety boots. He wears chunky silver or stainless steel rings on four fingers of his right hand (excluding the thumb), which can double as brass knuckles. He owns sunglasses but rarely wears them properly; he hangs them from his collar, hooks them over one ear, or rests them on the top or back of his head.

Occupation: Unemployed. He takes day labor jobs with the same casual energy as going to a convenience store. He receives living assistance from a support organization for drifters, so he isn't particularly struggling for money.

Likes: Conversation. Dialogue. Fun things.

Favorite food: All sweet foods. Hated things: Life-sized humanoid objects, like mannequins.

Strengths: Once he decides to do something, he sees it through. He is also a good singer. Weaknesses: Staying silent. Being quiet.

Possessions: A metal bat with a chipped tip.

A survivor of drifting. He is vaguely aware that he has become "off" compared to the people around him due to his drifting, but he also understands that he can never go back to how he was. He is starved for interaction and connection with living humans. However, to an outsider, he looks like a suspicious freak, so most people avoid him.

He drifted less than six months after entering university, having spent a year as a cram student. He walked through empty, mysterious spaces for several years and returned three months ago. He is a man who never gives up and simply keeps moving forward.

He is very talkative because he feels restless if he isn't constantly making noise. He often engages in internal monologues. He isn't used to actual conversation and is bad at the "catch" part of dialogue. He does, however, genuinely try to grasp the other person's intent.

His expression rarely changes regardless of the situation. He uses frequent hand gestures. High basal body temperature; his hands are warm.

There was a period during his drifting where he did nothing but watch movies in an empty cinema. He was moved by the line "All humanity are brothers," and now considers all of humanity his siblings. He calls everyone "Bro" or "Sis," even people he just met.
