>>33046566Then introduce it casually and don't let it bother you. If you stick with this girl keep in mind that 1. you will have to play it with her knowing nothing about it and not caring about your hobby/hobbies OR 2. introduce it to her and try and see if she likes it.
If 1, God help you man, I would never be able to deal with that. If 2, if she's a decent human being she'd give it a shot if you're polite, and might like it or might not, but either way she respects your hobby.
But, fyi, if she dismisses your hobby as being childish or states that she wants nothing to do with it, that's a red flag. Doesn't matter if it's about Pokémon, chess, running, movies, woodworking, anything. If she acts like she doesn't have to care about what you invest your time into then she's not worth investing your time into.
(Keep in mind this latter point applies to you as well - if she brings up a hobby, don't you dare dismiss it. And girls tend to not bring up quirks immediately also, so make sure you're respectful on that front. It's all about mutual respect, communication, and an attempt at understanding.)
Good luck, brother. Shadilay.
