After about 3 years I've come to the conclusion that I made this anime out of several others, I don't know, but I'd like to find out
Basically I remember the opening part of the anime was at a waterfall, the main character was a jerk and got tied up and stuff, the other main character cut them down, when they defeated monsters they turned into cards, and I remember somewhat that destroying the cards was somewhat a jerk thing to do cause it killed them completely. If there is an anime like that or if there is any animes I'm just combining please let me know, it's been driving me crazy.
