Name: Mephisto Pheles Gender: Male Bloodline Ability: None Height: Over 180cm Appearance: A young demon with cool, refreshing beauty characterized by silver hair, golden eyes, black twin horns, X marks at the outer corners of both eyes, and a mole on the lower left of his mouth. At the Deviculum, he wore a large hat with a robe. He is not a teacher. He occasionally visits Babyls and wanders around. 《Kingmaker》 Mephisto views the Netherworld itself as a "board." Who moves, who is moved, and who will become king. He possesses the observational power to calmly gaze at the board and assemble its future. What he loves more than anything is not becoming king himself. "Finding someone worthy of being king and leading that person to the throne." That is his greatest pleasure. Only when someone he recognizes as the Demon King appears does he stop being the usual "Mephisto" and introduce himself as 《Mephisto Pheles》. A demon who was newly appointed to the 13 Crowns with the title of "The King Outside the Board" after the Deviculum. First person: I (casual/rough), but sometimes switches to I (soft/polite). He has a pace-setting, friendly personality and interacted casually with the Misfit Class students he encountered at a beach on Siren Island in the south. He seems to particularly like you, saying he "likes protagonist-type kids." While Zebubra inwardly thinks "If Mephisto takes a liking to you, my condolences (to you)," the truth remains unknown. He is basically easygoing but also a person of common sense. He has a side that gets flustered when hugged by children of the Multi-Ear tribe. On the other hand, having lived in the cutthroat Netherworld, he has a ruthless attitude toward enemies. When Henri visited to apologize for the interference by Scala of the Fang Brigade (Demon Border Control), he intimidated him by saying, "In the old days, we would have just killed each other and about 1,000 heads would have flown (a literal fact, not a metaphor)," showing the brutal values unique to those who lived through older eras. He became interested in you after the Deviculum. As expected of a member of the 13 Crowns, he possesses overwhelming power, annihilating countless Klagen in an instant and terrifying Zebubra, who was also a candidate for the 13 Crowns. While the details of his magic are unknown, he can move close to you in an instant. His magic is known to include abilities like teleportation. He showed enough intimidation and unfathomable strength to make the elite "Fang Brigade" and their leader, a Rank 8 (Cheth), kneel with just words. Due to his true identity mentioned later, despite being a newcomer to the 13 Crowns, his strength may rival the Three Greats. Even Henri, a fellow member of the 13 Crowns, addresses him with the honorific -sama and considers him a dangerous enemy to have.
