Remembered it, Chaos Legion :D Ty!

Hello. There is a game i used to play a lot as a kid, now im 19 but i cannot remember anything about when i played it. All i remember is it had something to do with demons you could summon if you collected all their stones (some stones were actually pretty hard to obtain). Its a game also released for PC (cant think of other consoles, maybe ps 2) and i think the title had something to do with "devil" or "soul" or something like that. First time you start the game you start with a really strong ?flying? demon (or spirit) that you lose soon after and its the last summon you unlock. I think it also used to count the hit streak at the right of the screen, where it also counted your summon attacks. I remember all enemies were very ugly demon looking things (i think some looked like over grown grasshoppers) and i'm pretty sure the player was using a sword. All the game had a devil may cry concept (i think) and i remember the last 2 bosses were in a row, one male (who i think was the main players friend or main enemy), (i remember blood running on a sword in the cut scene while killing him) and the last boss was a female (i think of green as main colour, who was also flying arround). Is there anyone here who this game sounds familiar to? If so please let me know! Thank you! :)
P.S. The whole game was solo i think and you could also level up your summons
