Ruval Phenex is the heir of the Phenex Clan. He is the eldest son of Lord and Lady Phenex and the elder brother of an unnamed second brother, Riser Phenex and Ravel Phenex.


Ruval, like his younger siblings, has blond hair and dark blue eyes. However unlike Riser, he wears proper noble clothing.


Fitting to his noble-like appearance, Ruval has a kind and noble personality. Unlike his younger siblings, Ruval displays no arrogance or condescension and is polite and respectful from the beginning.


Not much is known about Ruval, other than the fact that he had been in one of the Top 10 rankers in the Rating Games and is rumored to be promoted to an Ultimate-Class Devil soon.
