Ensemble Dark Horse: Miya is greatly loved by the readers due to her close friendship with Yui and being more of a realistic girl.
Esoteric Happy Ending: Dawn Ending, which is the good ending. Yui can keep her friendship with Miya and the two go with the latter's family to a festival, but she still lives with Sakamakis and continues to have them drink her blood. However, it's implied that Miya will try to help Yui escape again.
Fan-Preferred Couple: Many readers really prefer to ship Yui and Miya more than shipping the former with any of the Sakamaki brothers.
Les Yay: Yui and Miya share plenty of moments of this in the story.
Rescued from the Scrappy Heap: Miya gets praised since readers love the fact that she's an OC who cares about Yui and tries whatever she can to help her. Something that many readers say that it's refreshing to see since other Diabolik Lovers OCs tend to be mean and rude towards Yui.
They Wasted a Perfectly Good Character: Miya's grandfather. Miya often talks about him and how he revealed the facts to her about their family bloodline. However, he never once makes an actual appearance in the story.
The Woobie: Yui certainly is this like in canon. She's pretty much treated like crap by the brothers who only want her for her blood.
