J-Stars Victory VS is an arena brawler akin to Anarchy Reigns and Gundam Extreme VS and is a Spiritual Successor to Jump Ultimate Stars. The game was created by Namco Bandai and Spike Chunsoft to celebrate the 45th anniversary of Weekly Shonen Jump. The game features 2-on-2 player combat where the player teams up with a friend or the computer to fight against an opposing team. Each team also has a third slot left for summoning a support character.
There is also a story mode where you can meet many other characters who aren't playable or assists. These characters aid you on your quest by giving side quests so you can obtain items to enhance your fighters or the ship you travel on, The Memorial Jump. Once you go through 4 different paths in the story and fight some people, you'll get to the J-Festival!
