Shin Megami Tensei: DeviChilEdit
A Cerberus and the demon partner of Setsuna Kai, Cool appears in the first episode as the brainwashed minion of Lucifer. He randomly attacked homes of the Mokoi using his fire spells in the Expanse, which caused rocks to rain down on Earth. Setsuna frees him completely from Lucifer's control by kicking a rock at him. He hates being called a dog and initially didn't like being Setsuna Kai's partner, and the two butt heads often.
