Zephyrdor Glasya-Labolas was a candidate to become the next heir of the Glasya-Labolas Clan, after the previous heir was killed[1], Gremory seal-disclaimeruntil Iryuka Glasya-Labolas from the main branch was chosen over him, after he suffered an emotional defeat from Sairaorg.


Zephyrdor has lots of black magic-like tattoos on his face and on his upper body. He has green hair (blue in anime) that stands on its end and matching eyes. He also has pointed ears. Zephyrdor also wears ornaments on his pants as they were stated to "jingle and clank".[2]


Zephyrdor has a personality reminiscent to that of a delinquent, as evidenced through his quarrel with Seekvaira. He is also quite arrogant and has a problem with authority, as seen with him mocking Sairaorg despite the latter being on top of the 72 Pillars in terms of ranking.[2]


Zephyrdor Glasya-Labolas came from the Glasya-Labolas clan. He became a potential candidate to be the next head of the Glasya-Labolas clan after the intended heir died in an "accident"[3], whom in truth was murdered by Diodora Astaroth[4]. Following this he was sent as a representative of the Glasya-Labolas Clan in the Young Devil Gathering.


Birth of the Breast Dragon EmperorEdit

Zephyrdor appears in Volume 5 in the waiting room for the opening ceremony of the Young Devils Gathering, quarreling with Seekvaira Agares after he made fun of her being a virgin. The argument was put to stop by Sairaorg Bael who knocks Zephyrdor out after ignoring his warning and calling the former "the incompetent son of the Bael". He later faces off against Sairaorg in a Rating Game, losing badly to the latter. After the Rating Game, it was reported that Zephyrdor lost his will to fight after his demonic powers proved to be useless against Sairaorg.
