As Yuto is a baby, he isn't very developed as of yet. He is pale skinned with brown-black eyes and is usually seen smiling widely or crying. Yuto has a short puff of bangs that are very pale orange-brown in color in the center of his forehead. He is noseless just like many other characters in the game.
Yuto often wears a light blue one-piece baby outfit with a pale yellow themed bib. He can often be found holding a light pink bear shaped rattle.
