https://www.mangago.zone/read-manga/shaman_hong_won_pyo/ ( I don't remember much but it fo include team building and fighting against..? Evil Organisation ? It has shaman and ghost thing)

https://www.mangago.zone/read-manga/the_evil_ring/ ( this is more about fighting against the system but they do have power system, so supernatural+ modern fanatsy aspect of scs matches with it )

https://www.mangago.zone/read-manga/the_crow/ ( supernatural fighting against ghoul, this one matches to special cs like 90 percent)

Thank you
