Nuts

Nuts is one of the mascots in Yes! Pretty Cure 5 and Yes! Pretty Cure 5 GoGo!. Like his friend Coco, Nuts can transform into a human form which he uses in public and to interact with those who do not know his identity, going by the alias Natsu-san. In his human form, he goes as the clerk of the jewelry shop called Natts House. Although Nuts 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. When in his fairy form, he ends his sentences with "~natts".

Nuts is usually serious and distrustful, almost the completely opposite from Coco. Because of his traumatic past, he uses time to get close to people. However, he has often shown to be extremely stubborn and sharp-tongued, not wanting help from people when facing problems.Nuts 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, Nuts will honestly feel remorseful if he has hurt someone's feelings regardless of his beliefs.

Nuts is able to be in his human form as long as he would like, but he prefers staying in his mascot form as staying in his human form is tiring for him. He transforms back into his mascot form easily, just like Coco. Natsu is careful with his actions, though will not hesitate if he has to save those who knows his secret.
