Pokemon: I'm a Coward in This World

I've arrived in the world of Pokemon, but I can't control this body... Why am I only a consciousness? I'm actually an idiot! Hey, hey! I can finally control my body, but it has a side effect... Timid! My body is so timid! It gets scared whenever it comes into contact with Pokemon! But my conscious mind isn't timid at all!... Timid? Does that mean the Timid nature? A Pokemon with a Timid nature has reduced Attack and increased Speed! Wait, why is my Attack reduced? My Pokemon's Speed is going up! (The story starts slowly, and the protagonist mainly uses a rain team in the early chapters.)
