Yosuke is the first official member of the Yasoinaba investigation team. He represents the Magician Arcana and his Persona is Jiraiya. Even though he’s well regarded on the team, Yosuke’s often the brunt of things on the team, and seen as a bit of a wimp, resorting to cleaning, the fodder, and having an odd reactions with bears. Despite all this, Yosuke is an incredible and Reliable fighter. When faced in a fight, he does his best no matter what.
It was on top of a snowy mountain that he and Yu met the heroes themselves. After defeating Aggron and freeing them, they were more than happy to join. Since then, Yosuke has had a few fights, one of notice being his battle against Top General Larvesta with his Dragon Kunai.
After leaving the Dimensional Heroes, he along with his friends were recruited by the Heroes Coalition and currently works as a Solo Hero but is a part of the Inaba Investigation Team.
Yosuke has slightly unkempt fawn colored dyed hair and brown eyes. At both his school and inside the Midnight Channel, he wears his Yasogami High school uniform, along with a white V-neck T-shirt with long sleeves and a pair of red headphones (save for two occasions, he is never seen without them). Inside the Midnight Channel, Yosuke also wears orange glasses.
Yosuke is a clumsy transfer-student who arrived six months before the protagonist. He is often the target for jokes about his lack of muscles and body strength, and fights with blunt, double-handed objects such as wrenches, but moreso knives and kunai. The protagonist first sees him crashing his bike into a garbage can, the first of many times, but he doesn't introduce himself to the protagonist until he helps Yosuke by getting him out of a garbage can. Yosuke doesn't usually think before he says something, which results in him sticking his foot in his mouth, and unintentionally insulting someone, including Kanji Tatsumi about his sexual orientation. He tends to be a bit of a wannabe ladies' man and has a fascination for girls, forcing the girls to enter a beauty pageant they can't back out of. But beneath most of that (more so in the original game), he shows great insight with decent deducing, and is often on task of the situation on hand, and can be very serious at times. Along with that, he is described by the other members of the Investigation Team as too nice, even from his ownHeis words.
He is a cheerful trickster with speedy, unpredictable moves. His Persona is Jiraiya, master of the wind. He uses knives and kunais as weapons.
- He along with Yu Narukami, Teddie, Kanji Tatsumi and Rex Salazar are known as Neo-City's One Direction after singing and dancing in the streets one time.
- In later chapters, both him and Tatsumi scored themselves a date.
