I watched this anime quite a few years back and to this day, it remains one of my favorite anime's. This fun little anime has the laughs and definitely the action. People all from different parts of the world or universe fall into some game world where they have to battle with opponents for prizes?? Yes please! And yea the main lead is overpowered but so what? It just makes his character more interesting and challenging for his opponents. I suggest you all give it a chance and watch this splendid anime!
