Ionis

Ionis is a Rune Knight from Noblesse Exaltée.

A human butler of refined demeanor who serves Rozelstine. As humans are of extremely low status in Noblesse Exaltée, the amount of freedom he and his fellow retainer, Lilia, are allowed is most unusual. He appeared to the vampire king after the end of the Imperial Crusade 200 years ago, requesting to enter his service...though few know the exact circumstances behind this.
