He seems to dislike things being 'boring,' as he uses this as an insult against Fujisaki. Yuri is known to be extremely flamboyant and over the top, being described by Akemi Keiichi as 'having a few screws loose, so he's hard to hold a conversation with.' He also tends to laugh chaotically at random, and change pitches. Yuri wears what appears to be Mormori's standard uniform, with a pink sweater and no socks or shoes. Yuri has yet to be seen without a pair of sunglasses, and often dons various other accessories, such as chokers, necklaces, bracelets, and rings. He has multiple lobe and cartilage piercings, as well as a tongue piercing and a navel piercing. Yuri has medium length pink hair which is somewhat unkempt and all over the place.
