Thread: Anime/Manga Help

Trying to remember an Anime that I watched quite some time ago and seem to be having issues recalling the name of it. The Anime consists of a teenage guy as the main character who is given a bank card that can withdraw money from a parallel world so long as his balance doesn't reach zero. In order to win more money, you have to fight other people who take part in this second world. If you lose all of your money then pretty much it is game over for you. The "fake money" coming into the real world causes some major issues and is causing the real world to collapse. The primary character ends up trying to help save the real world from being destroyed/taken over/collapsing/disappearing (it is one of those options lol). If you happen to know what this Anime/Manga is please help me out! Much appreciated in advanced.
