Fenrich "Moonlight Fang"

About

Fenrich is Valvatorez's ever-loyal servant. He is willing to put his master's will and well-being above all else, even his own life. He constantly praises his master and dismisses any of Valvatorez's quirks as one of his "formidable powers." His attitude toward others, however, can range from disrespectful to rude to outright threatening, especially if they themselves are disrespectful towards Valvatorez.

Despite how he occasionally refers to Valvatorez as "Lord Val", he dislikes any nicknames that others give either his master or himself that isn't out of respect, such as Fuka calling Valvatorez "Valzy" or himself "Fenfen" (although he strangely makes no remarks on Artina calling him "Mr. Vampire" or "Mr. Weirdo"), and becomes very irritated or uncomfortable if he is personally called a "tsundere." Fenrich has also repeatedly shown a cunning and manipulative side to him and will use whatever means necessary to achieve a objective, even to the point of manipulating his own master.
