It shocked Dadalia for a hundred years that he actually traveled through time and space.
A self-proclaimed system told him that if he wanted to go back to his original world, he needed to become a strong man in another world.

I originally thought that playing tennis would be difficult, but I didn't expect that people in this world could play tennis so well without any elemental reactions!
Dadalia's fighting spirit was aroused and he wanted to fight!
He is Dadalia who keeps getting stronger.
