Mayu Pissed Off

When Nini was pushed off the building she fired her Gun ( [link] ) (zoom in and that picture and you see the head shot) When that gun was fired it hit, but sadly since Nini died she failed to see that Mayu lived.

Mayu is only alive because she is already dead. The Teddy bear she carry's keeps her standing because of a curse.

Mayu is pissed off that she got hit. Her Yandere is pushing her to the limits.
Hopefully she calms down before she reaches her limits.
God knows what will happen if she does.
