Before anything, these aren't my own creation, these characters are from a Netflix anime tv show.
Mikoto Suoh: the 3rd and red king
Izumo Kusanagi
Misaki Yata or just Yata
Rikio Kamamoto
Myranda Ricketts
These are the reds
Reisi Munakata: The 4th and blue king
Saruhiko Fushimi
Seri Awashima
Scepter 4
These are the blues
This story is mostly about a relationship between Mikoto and Myranda.
