Hachiko is a dog.
Ai No Miko: You may have noticed a dog outside of the Akiba Tower. His name is Hachiko, and he has become a symbol for loyalty here on Yokai Isle. Hachiko was once owned by a wise teacher, who stayed in the tower. Every day Hachiko would greet his master at the door of the hotel until, one day, his master did not return from teaching.
Sadly Hachiko's master had passed away while at work but every day, at the same time Hachiko comes out to see if his master will return. Eventually the people of the town began bringing him food and treats.
Hachiko still waits for his master's return but he knows that every citizen of Akiba is his friend, and is always happy to greet new friends. He became such loved and respected symbol for loyalty that my father, Emperor Daisho, changed the hotel into a barracks for his most loyal ninja and samurai warriors and changed the name to Hachiko Tower!
