Hey! I am just recently getting back into watching anime, used to watch a lot of when I was younger. Came on here trying to see if anyone could help me with the name of a anime i used to love. Basic storyline is all the main characters are dead and have to play a game to get their lives back. They get summoned to a apartment where there is a black cube or sphere which they get outfits and weapons needed to to kill monsters. If anyone is able to help me out with the name of this it would be greatly appreciated.
