The Red Dragon Emperor's Awakening
He talked with Rias' father at the end of Volume 2 after the defeat of his son at the hands of Issei, feeling pleased because it had taught Riser that the Phenex Family is not absolute and what he needed was the feeling of defeat.

Trivia

 * In both the light novel and manga, he and Lord Gremory discuss about the Welsh Dragon and the impending arrival of the Vanishing Dragon, while in the anime this conversation is held between Sirzechs Lucifer and Grayfia Lucifuge.
 * In both the light novel and manga, during his talk with Lord Gremory he states, "Both of us already have pure-blooded Devil grandchildren." This means that Ruval Phenex or the other unnamed son already has a son or daughter.
