Akemaru

is a ninken from Konohagakure's Inuzuka clan.

Appearance
Akemaru resembles Akamaru who is based on a Great Pyrenees, though rather than being white, Akemaru has red fur, similar to when Akamaru eats soldier pills.

Naruto Shinden: Parent and Child Day
Akemaru and Akamaru accompany Kiba Inuzuka to their local toy store, where Kiba plans to buy a Kurama doll for Tamaki. There, they run into Naruto Uzumaki and his daughter, Himawari. Because the Kurama doll is in limited supply, neither Kiba nor Naruto are able to find one at this toy store. Himawari cries with disappointment, and Akemaru and Akamaru try to cheer her up. Kiba offers to help Naruto find a doll for Himawari, so he, Akemaru, and Akamaru spend the day searching the village. They find one, but it ends up being stolen while Akemaru and Akamaru transport it to Himawari. The thief - a father who only wants to give his son a Kurama doll - is eventually caught, but Himawari takes pity on him and lets him keep the doll. Since Himawari doesn't want it, Kiba tries to intervene and take the doll for himself, but Akemaru and Akamaru bite at his hand to stop him.

Video Games
Although he is not playable directly, Akemaru replaces young Akamaru's character model as apart of adult Kiba's move set in Naruto Shippūden: Ultimate Ninja Storm 4.
