Koromaru

Koromaru a dog & a eighth member from Persona 3.

Personality
Koromaru is a shiba-inu who joins the Specialized Extracurricular Execution Squad in Persona 3. Koromaru was a stray dog that Fuuka Yamagishi and Yukari Takeba played with regularly. A housewife tells them that Koromaru's master, a monk from Naganaki Shrine, had died in an accident (about 6 months ago from June 20). Koromaru continued to protect the shrine and wait for his master's return. One night, a rogue Shadow is detected outside of Tartarus. The shadow wanders into the shrine area, where it is killed by Koromaru. Akihiko Sanada manages to reach the shrine, only to find the shadow defeated and Koromaru injured. Akihiko is very impressed at the dog's bravery and intelligence, and Mitsuru Kirijo makes sure that he receives the best veterinary care possible.

Shuji Ikutsuki decides to have a special Evoker made for Koromaru that he can wear and use as a collar. He also wears protective clothing and fights with knives. Koromaru joins S.E.E.S. after he recovers from his injuries. Koromaru cannot communicate directly with his dorm mates, but they manage to understand him through his actions and from Aegis translating for him.

Koromaru exhibits intelligence far above that of most dogs. He is fiercely loyal, and particularly close with Shinjiro Aragaki, who often feeds him special food and takes extra care of him. He is a fan of a show called "The True Battles of Real Men", which exhibits acts of courage from real people. He begs the protagonist to take him to the theater for a special showing of the final episodes of the show. Koromaru whines and runs around after the movie until the protagonist agrees to purchase the boxed set after its release.

Koromaru is called "a white beast with red eyes" by Akinari Kamiki, who's pen is stolen by the dog. Akinari doesn't seem to angry about the theft of the pen, but he will not talk with the protagonist until he retrieves the pen.

His Persona was a Cebrerus.
