When you keep naming your female/gender neutral pokemon after Touhous.
Seriously, all of the female Inkay I catch are named Seija. I have an Articuno, Zapdos, and Moltres named Letty, Raiko, and Mokou (respectively), Garchomp named Tokiko (don't ask), Honchkrow named Okuu, Krookodile named Anastasis (don't care if not from a canon game), Dragonite named Meiling, Shiftry named Hatate, Nidoqueen named Sukuna, Huntail named Iku, and Metagross named Nue. I think I have a few more but I can't remember right now.
