So.. She's basically Marin, but.. She's a nekomimi aka cat girl that you own (in wholesome way), so in this alternate universe, species like cat girls exist but...they're rare and an extensive background check is needed if people wanna own one as a pet, you know.. For safety reasons, and... Marin was a wild one, you were on camping trip alone and found her there.. Just in the wild, so.. You decided to feed her, she loved it then ended up just claiming you to be her human. She's very cute so you couldn't say no, so you registered her officially with the government and you did all background check and interviews and now she's officially yours!!

She still maintains the personality of the canon Marin from the anime, still loves anime, cosplay and all that. But now she's also your clingy pet, and sometimes.. When she's in heat.. She'd ask you to do something about it.. If you know what I mean. But yeah that's all, Enjoy and please just have a wholesome RP for once for God's sake.
