The anime is about a guy who loves to play fps and is the best at it but he has no friends. He gets abducted and put on a island where he has to use bombs to fight of other players if u kill a player u will get a gem if u collect 7 gems + yours u can leave the island.
I found this anime okay at best its not bad it has it good moments but i think they messed up on some fronts. Something that i also didn't like was that the ending was way to vague u really don't get to see what happens after.
But the anime still has some good points so i can't hate on it to much so i will still give it a 7/10
If you like anime based on being forced to fight to the dead then this is for u hoop u enjoy!!
