Peacock came with Rinne when she fell from the Prism Dimension. Peacock then split into 7 sparkles that are born to become Pair Friends. Rinne originally lived alongside with her in the Prism Dimension, with Peacock looking after her as her guardian. Peacock is formed when all seven Pair Friends are united.
Peacock is a pure white peacock with a rainbow heart on it's chest and a pink beak. On the top of it's head are blue feahers, while its tail is composed of five, long pink feathers.
