Chibiterasu (チビテラス) is the tiny, celestial wolf puppy and the son of Amaterasu. He is the main protagonist and playable character of Ōkamiden. Throughout his journey to save Nippon, Chibiterasu is given a number of different names by each of his partners: Mutt by Kuni, Squiddy by Nanami, Pooch by Kagu, boy or dude by Kurow and Pork Chop by Manpuku (in each case, he clearly showed how much he disliked being called each). Chibiterasu isn't really smart and can't understand much without a partner directing him (partly due to the fact that he can't read).
Much like his mother, Chibiterasu is benevolent, helping all those in need. He is loyal to his friends and determined to protect his partners as shown when he jumped in the way of multiple blasts in order to defend Kagu from Sen and Ryo. Unfortunately, he inherited several of his mother's "bad habits" such as a low attention span resulting in him staring into space when being spoken to, which sometimes leads him to go to sleep.
In the game, Chibiterasu takes the shape of a white wolf pup with crimson markings across his body, a tail shaped like a calligraphy brush (possibly how the Celestial Brush is used) and, at times, a Divine Instrument usually floating above his back, making him identical in appearance to his mother Amaterasu, only smaller.
