My only mahoyaku OC (right now) is Nana! She’s actually not a wizard :3 she’s the sage (replacement for Akira, like Akira just does not exist in my yumeverse GDJCHDH everything happens to Nana instead)

She’s FUCKING AWFUL!!! She’s 20 years old and, before getting isekai’d, has fucked her life up in like, literally every regard possible back in her world. like she’s in debt she’s unemployed she’s a terminal neet she has no friends she’s letting her bpd run her life and she has NO prospects. but then she gets isekai’d! and she’s…still just as shitty a person GDHXHSHS. Like she does not have any of the same virtues that Akira does, not even remotely💔 she has 0 redeeming qualities. and shes batshit crazy.

but!!! she like, pretty much immediately latches on to murr and shylock. she’s batshit crazy and they are also batshit crazy but in like a very fun and alluring way to her (and in a way that makes her want to do her best to make them Actively Worse People, which is already a stretch LOL)

she is definitely ? together with both of them, but not at the same time, it’s three different relationships (like nana+murr, murr+shylock, and shylock+nana LOL it’s not an OT3 / a throuple) it’s really complicated and I have a fackkkkkk ton of built up story for her just because it’s like. Really fun to get silly with her, esp bc Akira’s Redeeming Qualities drive a lot of the story in general but nana just. Doesn’t have any of those at all HHDVDHDHD

the way that Murr and Shylock both feel about her is definitely really complicated LOL. Murr likes that she gives him a lot of attention, and he likes that she’ll mostly do whatever he wants! He likes that she’ll play with him a lot and he likes that she shows a lot of favoritism towards him compared to other wizards in the manor, but then he also gets really jealous when she gives that attention to like…anyone else, even and especially Shylock LOL.

Shylock and Nana’s relationship is DEFINITELY super complicated but the crux of it is that like. Unfortunately, Shylock and Nana are both really good at metaphorically keeping pace with each other, and that pisses both of them off to no end GDHCHSHD. Like Nana definitely loves him, she loves both of them, and Shylock Does love her in a way, but oh my god they are like…catty divas towards each other. The only skill Nana acquired in 20 years of life before getting isekai’d was getting really, REALLY good at getting under people’s skin and pissing them off, and this talent really shines when it comes to Shylock. It doesn’t help that Shylock makes himself such an easy target because he has such Clear and Obvious buttons but also acts so umm. So Shylock about it when those buttons are pushed LOL.

Nana IS someone who Shylock trusts a lot, to whatever tiny extent Shylock is capable of trusting other people, and they do have occasional genuine moments of vulnerability with each other, a lot more than Murr and Nana necessarily do, but then they go back to Immediately never mentioning that again every single time LOL.

I also have an idol au for them! It’s my most fleshed out of my aus for them, but I should probably contain that to a separate infodump if anyone gaf bc this answer alone could already be WAY longer but I’m like. Trying to be tame, both with regards to keeping this answer from getting too long but also not unleashing my one billion horny thoughts about the three of them on main. That’s what my nsfw is for. GFJFHSHD i jas freaking love my evil little girl. She’s seriously so awful. THANK YOU FOR ASKING ABOUT HER MWAHHH
