In spite of the extremely dark nature of the franchise, there are some sweet moments.
- The relationship between the Mukami siblings. They're sadistic and masochists, but they have a deep familial bond with each other that grew from their time in the orphanage with each other.
- In Azusa's "No.01 - Vampire Ending", he and Yui appear to be Happily Married with each other and have three children together.
- Subaru giving Yui a chance to escape from the Sakamaki household, even providing her with a knife to defend herself against him.
- A rather unsuspected Pet the Dog moment from Ayato: he sneaks into Yui's room at night and sleeps beside her. But, he doesn't do anything. Not forcing a bite on her or trying to do something perverted. He just wants to be near her. He shows his soft side to her.
