|Part 6: Records of Oblivion|
Toko gets Azaka, Kokuto's sister, to investigate a strange case at her all-girls school, where some girls all stabbed each other or something, and then they all lost their memories... Toko theorizes that there are faeries going around stealing people's memories... Toko pairs Azaka up with Shiki for this mission, so that they can use Shiki's eyes to locate these faeries...
Azaka hates Shiki, because she is secretly in love with her brother and Shiki has started to take him away from her... Toko and Shiki have both already figured this out.. it's only Mikiya himself who doesn't know.
Azaka gets confronted by the student council president, who turns out to be the one controlling all these faerie familiars with magic.. she says that she's trying to get back at the class who drove her friend Kaori to suicide... Azaka tries to ask for her memories back, but the faeries can only take memories, not give them back...
Later, Mikiya calls Azaka/Shiki and helps them out by investigating on his own because he's worried about them, and he finds out that one of the classes at this school was involved in a prostitution ring, and Azaka figures out that's what drove that girl to suicide... Mikiya also found out that one of the new teachers there is a mage, and that's probably the one who taught the Art to the girl who's spreading these faerie incidents... Toko knows this mage as soon as she sees him... he has a very obscure power that lets him fulfill the fantasies of anyone around him... I'm guessing that's why Azaka and Shiki both think he looks a lot like Mikiya... Toko assures Mikiya that this mage is not dangerous at all.
