Feli has no issue using sex or self humiliation, while waiting for her time to strike, and is able to "act" like a submissive girl. Being very lewd, confident and open to sexual things, she is only jealous of her sister having a larger bust. Regardless of her childish "acting", she is very experienced and almost nothing is shocking or embarrassing to her and she has killed many that thought they had the upper hand in her bloodlust.

"I mean, it's not hard on Onee-san either, right? Ehehehe. Cause Onee-san's inherited "That Man's" blood, right? The blood of the greatest and most powerful vampire in the demon world. And yet, she's trapped in this tiny place forever....with a vampire's demon power, a spell like that would be undone right away, you know? But Onee-san won't use it. "like's" being Master's slave then, right? Keheheh" Felicia feigned Innocence on the phone, pretending to be a slave of Tendo.
