Our Group Cosplayed the Characters from Katekyo Hitman Reborn, Then We Transmigrated

A group of people cosplaying Katekyo Hitman Reborn and I transmigrate with my group chat friends. Thanks for asking. I'm in the future, and the person across from me is the protagonist from ten years ago, Tsunayoshi Sawada. They're attacking the future version of me, and I'm standing right in the middle of the battlefield with a game console in my hands. What should I do? Waiting for answers online.
