Bellote is a mythril ranked adventurer and the leader of Sky Wolf. Not much is known about Bellote on how he became a mythril ranked adventurer. He is a recognized adventurer in E-Rantel and looked up by others with respect and even worship.

As the leader of Sky Wolf, he was summoned along with his mythril ranked adventurers peers from Kralgra, Rainbow, and Darkness to discuss the appearance of the powerful vampire Honyopenyoko. Momon insisted that the Darkness will fight against Honyopenyoko alone, arguing that involving others in the fight would simply increase the number of victims. Bellote and the leader of Rainbow accepted his opinion and did not participate.

After the apparent defeat of the vampire, Momon's fame skyrocketed and allowed him to effectively monopolize all Mythril ranked quests in E-Rantel. While this slightly upset Bellote, he cannot help but recognize and respect Momon's abilities.
