YMMV / Tsukuyomi: Moon Phase

• Complete Monster: Count Heinrich von Kinkel was always a nasty customer, with his habit of sadistically tormenting and trying to murder the majority of the cast. As one of the eldest vampires around, Kinkel believes anything around him is a toy for his amusement or enemy to be destroyed without mercy. It's revealed in flashbacks of his fledgling Elfriede that Kinkel seduced a human woman, drove her insane and returned many years later when the daughter was a teenager. Kinkel turned Elfriede into a vampire before slaughtering the human family who raised her. He then forced her to drink the blood of her best friend, gloating how Elfriede was his slave. When Elfriede was done, Kinkle proceeded to gloat that her pain gave him joy to no end. I Hate You, Vampire Dad doesn't begin to cover it.
• Nightmare Fuel: Count Kinkel is a horrific monster who eclipses succeeding villains in evilness, and one of the first things he does is brainwash Hazuki to kill Kouhei by ramming a hand into his chest. The only reason he doesn't outright win is because of Hazuki's immunity to sunlight.
• One-Scene Wonder: The pink-haired bifauxnen from episode 8 that wanted to become Hazuki's slave. Instead she got drank from by Elfriede.
• Quirky Work: Studio Shaft did the anime, and the opening alone is pretty much a head scratcher.
• Squick: The OP in the first two episodes. You will never look at turtles in quite the same way ever again.
• Tear Jerker: Elfriede's backstory from episode 17. In an otherwise mainly lighthearted action-comedy, it's pretty tragic and horrifying. Count Kinkel seduced a human woman and drove her to madness before abandoning her...only to return years later when her daughter (Elfriede) was a teenager and proceeded to kill Elfriede's human relatives who were her primary caregivers. The poor girl was forced to kill her best friend/adopted sister Nina, her only comfort being a vow to live as long as possible for the life she robbed from the latter. Centuries of misery and torture abounded before Kinkel was finally brought down in the present after which she tearfully recounts her past to Ryuuhei, who thankfully gives her a shoulder to cry on... plus becoming a couple with her.
