PD 1: The blue one is Kaito and the Pink one Mizuki. PD 2: When i say Kaito is sort of in mafuyu's mind is beacuse of the sekai thing that is hard to explain, that the vocaloids(even though it was only miku and kaito who did that) can go to the real world without the phone of the owner of it whitout traveling to sekai. PD 3: when i say that Mizuki is in Mafuyu's mind i mean that Mafuyu is remebering Mizuki's words. PD 4: the last ´part is when she runs away.
it is a joke but literal resume of the niigo arc ender "Farewell My Mask" which was a Mafuyu focus.
