When the ninja world merged with the Pokémon world, the alliance, which knew nothing about the ninjas coming from the ninja world, launched an attack on the ninjas.
The power of Pokémon and the chakra of ninjas collided with each other, and only one person, Uchiha Izuna, became an opportunity for the integration and development of the two worlds.
