The Vexations of a Shut-In Vampire Princess anime has cast Riho Sugiyama (Pete in Reign of the Seven Spellblades) as Flöte Mascarail, a companion Crimson Lord to heroine Terakomari Gandesblood. Episode 5 of the series airs tonight in Japan.
The series is composed by Keiichiro Ochi (The Demon Girl Next Door), character designs are by Tomoyuki Shitaya (Food Wars! Shokugeki no Soma), and music is by Go Shiina (Demon Slayer: Kimetsu no Yaiba), all based on the light novels by Kotei Kobayashi and Riichu.
According to Yen Press, the publisher of the authorized English translation of the light novels, the series is about:
Three years into her life as a shut-in, vampire Terakomari Gandesblood (Komari for short), awakens to find she’s been appointed as a Commander in the Mulnite Imperial Army! The thing is, her new unit consists solely of belligerent ruffians who revolt against their superiors at the slightest hint of weakness. Although Komari hails from a line of vampires as powerful as they are prestigious, her refusal to drink blood has made her the picture of mediocrity—scrawny, un-coordinated, and inept at magic. With the odds stacked against her, will the help of her trusty (and slightly infatuated) maid Vill be enough for this recluse to blunder her way to success? Or will Komari rue the day she ever left the safety of her room?
