This is your typical isekai story where our protagonist James dies and is reincarnated into the Multiverse. He will obtain the Ultimatrix.

The story will be exploring different worlds from a hub world. Each universe will largely follow the cannon with a few twists and turns. The girls will be present in the story and have their own story. They might fall for our protagonist a bit easily. There is no system so the protagonist is on his own however the hub world will provide basic resources. The character will be strong but not overpowered.
