Fuuta Okeya is a normal 14-year-old boy, except for the fact that he has the ability to see ghosts. A cute girl transfers into his class one day, but acts particularly aggressive towards him. This girl called Kouko Ishigami is followed around by a ghost called East. Fuuta tries to get along with her but ends up failing after she sees the birthmark he usually keeps covered. She then declares him as her enemy, his birthmark as a cursed brand and claims they have a long history, while talking about reincarnation. Who is this girl and how are they connected?
Standing in the Battledome
Spirit Circle is a powerful but unbalanced verse. It's characters are glass cannons. They have at least 2 to possibly 3 planet level characters with massively hypersonic+ attack speed. They also have various soul based abilities, characters who can exist inbetween time and space, intangibility, time and dimensional travel, limited wish granting and reincarnation.
Physically, they are unimpressive.
