Amaterasu *cannot* speak, she can only bark. However, Issun does all the talking for her and himself. Amaterasu is known for being quiet, mature, and kind. She always aids those in need and she has access to the 13 celestial brush techniques. Issun is very talkative, as he comments on almost anything Amaterasu encounters. He is reliable, and adventurous, but he has a short tempter and can't stand being called a bug. He is also very blunt and rude, and calls Amaterasu, Ammy.
