Chibiterasu 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's various partners give him other names—Mutt by Kuni, Squiddy by Nanami, Pooch by Kagu, boy or dude by Kurow, and Pork Chop by Manpuku—although in each case he clearly shows his dislike of the name. Chibiterasu isn't very smart and can't read, so he can't understand much without a partner directing him.
Nine months after the defeat of Yami, demons have mysteriously returned to plague Nippon. Sakuya, the Konohana Wood Sprite of Kamiki Village, desperately tries to summon the Sun Goddess Amaterasu back from the Celestial Plain. Instead, Sakuya and Issun are surprised by the appearance of a small wolf puppy who looks like a young version of Amaterasu (who is in fact her son). The puppy, "Chibiterasu", sets out on a journey to save the people of Nippon.
During his adventures Chibiterasu teams up with a number of partners, including Kuni and Kurow. After restoring Hana Valley and Shinshu Field, Chibiterasu restores Agata Forest and rescues the mermaid, Nanami from the Witch Queen. Chibiterasu joins forces with the mermaid to defeat Bullhead, an oversized catfish that has flooded Agata Forest. When Bullhead is defeated, Chibiterasu is swept away to Ryoshima Coast.
Chibiterasu journeys from there to Sei'an City, where he meets Kagu and defeats Sen and Ryo. After defeating the pair, Kagu is kidnapped by King Fury. To save Kagu, Chibiterasu meets another partner, Kurow, and enters the ruins in North Ryoshima Coast. After a long journey, including a trip back to Agata Forest and a thundercloud, he finally confronts King Fury and defeats him.
Kagu, Kurow, and Chibiterasu celebrate until a new character, Akuro, shows up and tells them he will bring a reign of evil to Nippon, and then says he is heading back in time to find Orochi. Chibiterasu and Kurow, with the help of Gen, head 9 months back in time and find that Akuro can become an all-powerful being by bathing in the blood of Orochi. Kurow and Chibiterasu show up just in time to stop Akuro from getting to Orochi's blood, but Akuro simply heads to 100 years in the past and gets to Orochi's blood that way.
Akuro challenges Chibiterasu to a battle, and teleports Chibiterasu and all of the friends he has made along the way to the Dark Realm, whereupon Kurow turns traitor. Chibiterasu in turn defeats 4 previously met bosses and Kurow, and finally Akuro and Dark Chibiterasu, along with the now possessed Kuni. Not fazed by his earlier defeat, Kurow shows up and offers himself as a vessel to Akuro, who agrees, realizing that Kurow's body is better than none. Kurow then traps Akuro inside himself, and, after revealing that he has turned back to good, has Chibiterasu and Kuni kill him so that Akuro dies as well.
Chibiterasu then returns to the present, parts ways with Kuni and his other his partners, and takes off for the Celestial Plain with Issun. According to Kuni's narration, though, he eventually returns to Nippon.
Chibiterasu is benevolent, as his mother was, 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 (which is 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. He can upgrade his smaller Divine Retribution into the Purity Reflector, and later the Truth Mirror. He can also obtain the same Glaive Amaterasu had: The Tsumugari. He can upgrade this into the Light Sword, and then the Feather Sword. Like Amaterasu, he can also obtain the Devout Beads: his first Rosary. Later, this can be upgraded into the Sun Beads, then the Mystic Beads. Unlike his mother, Chibiterasu can only upgrade his Divine Instruments twice, while Amaterasu can upgrade them four times. Only those who truly believe in the gods can see his true form, all others can only see him as a plain white wolf pup.
- "Chibi" is a Japanese word which comes from the い-adjective "chiisai" (「小さい」?; ちいさい), meaning "little". This word is often used to describe a cute being.
- Chibiterasu was originally designed as a joke by one of the game's designers, who drew him as a baby version of Amaterasu.
- Since Chibiterasu is both the child and grandchild of Amaterasu, in legends, he corresponds with Ninigi-no-Mikoto (「瓊瓊杵尊」?; also "Ame-nigishi-kuni-nigishi-amatsuhiko-hiko-ho-no-ninigi-no-Mikoto).
- Capcom released a series of Chibiterasu pillows and plushies shortly after Ōkamiden's release.
- Chibiterasu is incapable of doing several things that Amaterasu can:
- Chibiterasu is incapable of running (although he can move fairly quickly on his own) or digging. The player also cannot make him bark, though he does in the cutscenes.
- Chibiterasu is incapable of swimming.
- Chibiterasu does not form a trail of flowers after him as he walks, although he does create a short trail of plant growth behind him.
- Chibiterasu can't regenerate his ink pots like his mother can (possibly due to him being too young to possess such divine power), requiring Spirit Ink to replenish them, although when he runs out, after a short time, he recharges three ink pots.
- Chibiterasu is unable to jump more than once or jump off walls, unlike Amaterasu. He is also incapable of jumping from high ledges or cliffs during gameplay, his jump is also shorter in height compared to his mother's.
- Chibiterasu does not have an Astral Pouch, so consuming food only restores his health. He also cannot rejuvenate himself if he dies.
- Chibiterasu is unable to headbutt in battle.
- Unlike Amaterasu, Chibiterasu is illiterate (Meaning he can't read or write), and requires a partner to read for him.
- However, Chibiterasu is capable of several things Amaterasu couldn't do.
- He can use his Divine Instruments outside of battle, something Amaterasu was not shown to be capable of, or unwilling to do.
- Chibiterasu can also communicate with ordinary animals, something Amaterasu has not been shown to do.
- However, Chibiterasu is capable of several things Amaterasu couldn't do.
- Specifically 10 seconds after not doing any actions (outside of battle), Chibiterasu will sit. He will keeping wagging his tail softly in an upward, right then left motion while he keep moving his head in in a circular motion. His head moves slightly faster than his tail, making the motion completely non-synchronized.
- Chibiterasu had already learned Fleetfoot before the start of the game. It's probable that it was taught to him by Amaterasu. This also implies that Amaterasu canonically learnt Fleetfoot during the events of Ōkami, although it was originally an optional ability.
- Although Amaterasu is shown with Divine Retribution (later Solar Flare) during cutscenes, Chibiterasu does not have a Divine Instrument during cutscenes because of his special sprite, which only allows visibility of his Divine Instruments (floating on his back/neck) when he drops off any of his partners during gameplay.
- If Chibiterasu ran out of ink in battle, he will use ramming, bumping and 'butt-stomping' as an alternate fighting style.
- Chibiterasu Celestial Brush's ink takes on the rough apearance of charcoal rather than smooth ink
- Charcoal is a common drawing material in Japanese children art.
