I saw an anime short some years ago on YouTube. I can't find it anywhere. The things that I remember are:
- The "protagonist" is a girl with brown hair tied up and yellow clothes. She is a robot that is controlled by a group of some kind of small animal (I don’t remember what kind.)
- It began with her waking up, the animals beginning to control her to get up.
There was her friend (well, ex-friend) who had black hair and dark clothes and was a robot too, controlled by little bunnies. It seemed these bunnies killed one of the little animals of the brown-haired girl, so they started fighting, making the two girls start shooting each other with guns from their mouths.
The animals on the head of the girl spoke. I don't remember any other character speaking, maybe the mother of the protagonist saying to the girl she was late?
There was a guy too, it seems the protagonist liked him because of a photo she was holding on one part.
The title was probably in English, since there were so many people writing about the story being a representation of a promise that was broken that made three friends fight.
The protagonist killed the guy too, he was a ''ikemen''. I remember the animal inside the protagonist head saying something about it.
More things happen after that, but I don't remember so well.
