Quill is a relatively minor character who appears in episode five, in an early Stone Age world. She leads Hazuki and Lilith to her cave-village, where they notice an evil presence. A giant monster breaks out of the people's primitive shrine and Hazuki enters her first swordfight. The monster shrinks and disappears after its defeat. Quill loses the ability to communicate with Hazuki and Lilith after the defeat of the monster. It is suggested that Arya may have used magic to enable Quill to communicate with Lilith and Hazuki, possibly in a bid to make the two defeat the beast, which had been worshipped as a god. Quill does not appear in the game.   

Hatsuki is a highschool student living with her sister, Hatsumi, who she has a huge crush on. On Hatsumi's 16th birthday, she is suddenly surrounded by a green light and disappears in front of Hatsuki. She manages to follow Hatsumi with the help of a being resembling a fat baby chick (literally), ending up in a place called "The Great Library", which is full of different worlds stored in books. Hatsumi wasn't there, though, so the search for Hatsuki's great love begins and involves traveling from book to book.
