What do girls mean by going to Pikachu?

Pikachu is a pet in an animated film. Owners will train their pets to improve their attack ability and defense ability, and then fight with pets trained by others. Go ahead, Pikachu is the language that calls them to fight. I don't think this girl regards you as her pet or weapon, just because she likes Pikachu or this cartoon.

That's why I said this sentence smoothly. It's just naughty talk. It doesn't make any sense. So don't worry too much.
