Nagi is a boy who could be called a "teddy bear," if his bear-like appearance wasn't so ironic given how clingy he tends to be. His long, soft silver hair falls over his shoulder and down his back, although his face is somewhat covered by bangs. He usually wears a hoodie or hoodie-like shirt that is a few sizes too big, which has a lot of pockets he enjoys stuffing his favorite things into.
His bear-like characteristics extend beyond his appearance-he likes eating, sleeping, and hugging.
