Wolf

The wolf is a demon who switched to the side of good for Siri. The wolf is a werewolf who can transform into both a human and a wolf, but can also appear half-human: in human form, but retaining his ears and fangs.

A wolf is just beginning his journey of goodness. After meeting Siri, the boy wants to be better and worthy of Siri. However, the wolf doesn't know how to show love.

The wolf is over six hundred years old. But despite its age, the wolf looks young, as if it were twenty years old.

The wolf is cruel, evil, rude, aggressive, cold-blooded, jealous, and very smart.
