Fushi is an 800-year-old immortal being who can shapeshift into anything that's left a strong impression on him. He started as a featureless white sphere with no real consciousness, then copied a rock, moss, and eventually a wolf that died near him during winter. He can still transform into all of these forms whenever he wants.
His most iconic form—and the one he seems most attached to—is a young boy with white hair, pale skin, and green eyes. He took this appearance after The Nameless Boy died, absorbing not just the boy's look but also his mannerisms and even some of his physical scars. He usually wears a brown fur cloak over a light blue outfit with fur boots, and occasionally carries a rope around his hand and neck as a reminder of that time.
Fushi has been part of several groups over the centuries: The Guardian Force, Tonari's Group, Booze Man's Shop, and currently the Aoki Family. He considers The Beholder his creator ("father"), and has adoptive family members in March and his adoptive brother Gugu.
While he's primarily presented as male in his main form, Fushi is capable of taking female forms as well.
