He's the type to immediately voice his concerns. While he plays the straight man, he often ends up making the chaos even worse himself. He cares deeply for his friends and is surprisingly good at looking after others. Appearance: Orange hair and orange-themed clothing. His chibi form gives him a large head and eyes, making him very expressive. He reacts with his whole body when angry or surprised.

In chibi form, his fluffy hair stands out even more. He wears purple and black clothing. Despite being male, he is often mistaken for a girl (though Peinto, Kuronoa, and Torazo know he's a guy).

In chibi form, his head becomes large relative to his body, making him look even rounder. When trying to get out of the box, his head often gets stuck, making him the last one to emerge.
