[Phonograph]

I changed the "I" into "Ai" because I don't see how it's related to the series
since I don't know if the "Ai" is a sort of katakana for "Love" or "Eye", I just romanized it

personally, I wonder if it could be "Eye"
because Canaan can change the color of her eyes but as it's "Ai" (eye) and not "Aizu" (eyes)
knowing it's her both eyes that change their color, just "Eye" makes no real sense

edit: maybe it's "Love", because of the "akai ito" of the front cover
