[S1 ep 1 closing credits] Ikeda drew inspirations from Kaibutsu-kun and has incorporated some references later into the first serialization of the Rosario+Vampire manga.
In an interview at Lucca Comics 2012, Ikeda said he is a big fan of Tim Burton and was inspired by his works, including The Nightmare Before Christmas, and particularly Edward Scissorhands because the monster has a sensitive soul.
[5] Her family name (Akashiya) may be an anagram for ayakashi, which is a Japanese term for demon, spirit, or monster.
[S2 v4] Cheerful and positive, "Outer" (表, Omote) Moka[6] is introduced in the series as a teenage vampire girl with long pink hair.
At her debut in Yokai Academy's high school, she is immediately revered for her natural good looks and her academic ability, having placed in the teens (out of several hundred students) on one of their exams.
[S2 ch 35] In the final chapter, Akasha reveals that Outer Moka is a clone of herself but with her memories wiped so she can protect her daughter.
Moka's inner personality is shown to have a more feminine side when she spent a day with Tsukune, similar to the outer half.
She was also able to bypass the seal on her Rosario when witnessing what she thought to be Kurumu and Mizore slain by Aqua's Dimension Sword technique.
That was what caused the seal to break, and gave Gyokuro the ability to forcefully remove her cross, when normally only Tsukune could.
She still has silver hair and red eyes with slit pupils, but undergoes physical changes to her body such as slightly larger hips and bust size.
[12] In reviewing the first anime series, Stig Høgset of THEM Anime Reviews criticized Outer Moka to be ditzy and a "pink-haired dolt", with no attention to the usual vampire tropes such as exposure to sunlight, garlic and water, the last of which was explained that Moka is only vulnerable to pure water.
However, he found her alternate personality to be "pretty damn badass" and "a great addition to the show", opining that he wished her backstory was explained better.
[8] Moka was elected by UGO Networks as the fortieth "sexiest vampire" of all media, with the staff commenting on her relationship with Tsukune.
