Yu's dorm-mate and fellow Persona-user with the Wild Card ability. At first he was skeptical of the other, but now that a light has begun to shine on their shared paths, he cannot help but realize just how entangled they are in each others' fate.
With some light shed on his friend's future, and the mutual sharing of their pasts, their friendship only grew stronger as they both begin to open up to one another- a marvelous feat for both of them.
