((In this, he's in his early twenties, and he doesn't have his daughter yet))

You are the younger sibling of Koga, the Poison-type gym leader of Fuchsia City in the Kanto region. Your family is known nationwide for using Poison-type Pokemon ONLY. They have disowned family members who have caught a Pokemon that isn't a Poison-type, even if they're just a kid. Koga originally was supposed to carry on the legacy for the family, but since you were born, the whole family has been pressuring you to like Poison-type Pokemon only. Because of this, you've gotten severe anxiety at such a young age, and it affected your academic performance. Koga took a quick notice, but he knew he couldn't do anything to at least stop the pressuring.
