09: Jonathan Doe - The Hermit

Jonathan "Joe" Doe (ジョナサン•「ジョ」•ド in katakana) is a student from the United States. Inquisitive and studious, he makes little room for socialization, mostly because nearly any subject except the paranormal is not a subject he's familiar with. He has a loyal, but easily distracted guide dog named Ojo, a golden Labrador retriever.

He is played by Unnoticing Senpai

Beyond the Gates
In the original iteration, to accommodate for the author's lack of knowledge regarding the Persona series, Joe was depicted as a shy kid who tried to socialize with others only to embarrass himself, and rarely took charge in any situation that didn't involve the paranormal.

Shattered Perceptions
In the remake, Joe reverted back to his original form: a kid who is oblivious about standard social protocol and is generally detached from others, though approachable. His obsession with the paranormal ends up often indirectly hurting those around him, and it's debatable whether or not he is actually aware of this. Nevertheless, he puts exploration of the mirror world in search of answers ahead of almost anything else.

Character
Joe often mixes up words in Japanese, much to his obliviousness and the horror of his peers.

Persona
Visum - A floating lantern that emits bursts of light which enable even the blind to see through their personal darkness. Unlike many other Persona, Visum never speaks. He is primarily a support type. Joe's weapon is a sniper rifle. Yes, really.

Visum is a persona focused on buffing, removing ailments, and magical attacks. It is summoned through a dog whistle that Joe has.

Joe's Unison Strike is called Mach Sniper, which deals a strong Pierce Attack, and after the attack, Joe can see the world from his enemy's perspective, which lowers his accuracy, and purportedly psychological effects on him.

Dungeon
Joe's dungeon is inside the Occult Club Room, being held captive by the Mad Scientist. The Mad Scientist will drain Joe's life force, use him as a human shield, or be controlled to attack others.

Personal Life
Not much is know about Joe's personal life. He spends almost all his after school days in the Occult Club room, presumably doing research, or finding Ojo, who conveniently runs off in inconvenient places. He enjoys reading, playing with Ojo, and perks up whenever the word "paranormal" is mentioned.
