Natts

Natts is a squirrel-like mascot. He can transform into a human. Although Natts cannot do much in the human world, he is properly able to fight using his tail in his real form, though mostly uses this when he is annoyed at Coco.

Personality
Coco describes him as a good friend, comparable to the relationship between Nozomi and Rin. Natts is usually serious and distrustful, almost the completely opposite from his best friend Coco. Because of his past, he uses time to get close to people. However, he has often shown to be extremely stubborn, not wanting help from people when facing problems. Natts also believes that the truth is always the best, and thus never lies about anything if possible. Because of this belief, it is hard for him to apologize or say things he does not mean, because his simple logic is different from others'. However, Coco also tells Natts that a part of his character is that he feels bad if hurting someone's feelings regardless of his beliefs.
