I Cosplayed as Mori Ogai and Ended Up with Three Kids

I was cosplaying gender-swapped Mori at the CP20 convention when I transmigrated! Is this the rule that says cosplayers have to transmigrate? But why did I end up with three kids? An ordinary one I can accept, but what's with Ranpo the cat, Dazai the cat, and Yosano the butterfly? I'm really not your mom! The pairing is Fukuzawa/Mori, but Fukuzawa only gets a supporting role.
