In a route somewhere in the Kanto Region..

Chase was walking in the current route, with an Eevee on his head. Both of them were looking out for any Trainers or Wild Pokemon, and also heading to the next route

Chase muttering: I wonder where all the trainers n' pokemon are, I'm eager for something to happen.

chase seems pretty confident after catching 127 pokemon, which is almost all the pokedex

Eevee: Evo!
