The idea of a Yuu that's smart in NRC:
Not just intellectually, but also street smart and emotionally smart and physically very capable.
Like the type of person who meal preps, studies, exercises, and honestly an overall normal, well rounded person.
Something that never lasts long at NRC yet here they are.
(As you can probably tell by now I dislike the stereotypical Y/ns, or the new chaotic versions. The second version is very entertaining but far away from who I actually am as a person. I also dislike the idea of Yuu's only purpose being to thirst after characters.)
Side note: This is an HC, pick out the ideas you like, throw out the ones you don't like.
The Prefect, who remains the top student of the first years, for multiple reasons.
One of them being the fact that they received higher education, either by a tutor, or by them pursuing a higher education as they are older than their fellow classmates. Or they got the Riddle treatment.
The Prefect keeps making deals with Azul even when the first year friend group yells at them to stop and keeps getting out of the deals before they lose something and it ragebaits Azul so much. Azul and the Prefect have a bit of a love and hate relationship going on because Azul wants to beat them SO MUCH and the Prefect keeps escaping them like two miliseconds before they are caught. (Aka the street smart part.)
They also keep working part time at the Mostro Lounge and is the only reason Floyd is consistently engaged and working whenever they are there. Aka the second reason Azul has a love and hate relationship with them because they keep jumping out the window (metaphorically and literally) whenever he offers them a full time job.
If the Prefect ever gets a full time job at Mostro Lounge, Jade will quite literally book them for every day he's working, or every day Floyd is working, or just every day. The Prefect is NOT seeing the light of day again.
The Ramshackle dorm is probably a little bit cleaner than in canon for several reasons.
Riddle keeps sending the Prefect to tutor Ace and Deuce and somehow whenever he does that, Vil sends Epel who's a dumbass who drags Jack along with him and then Ortho joins for socialization and then Lilia pushes Sebek into it so he can make friends.
Imagine Grim and the Prefect have to add their test scores to each other's and divide them in half to get their actual score because they're a "2 in 1 deal".
The Prefect is quite literally the only reason Grim has not been expelled for academic failure and the teachers KNOW it. (the Prefect is scoring 100s every test for a reason lmao.)
The Prefect also probably goes around doing stuff for others when they are free, like speedrunning cooking for Jamil whenever Kalim throws a party, or organizing a study group for their other friends, like Kalim, Ruggie, Cater, and more with Riddle and Azul as the other two tutors on occassion.
They are pretty street smart, so I'd imagine them doing tutoring on the side for paying off bills, and bothering Crowley until they get paid their promised allowance, and doing random side quests for Sam to get discounts.
They did so many side quests for Sam that they somehow get 50 percent off all of Sam's products. No one knows how. (There is some parental favoritism in there.)
I'd imagine they probably save coupons, and befriended Ruggie out of their shared financial situation. (They're crying in broke.)
I can also definitely see them being friends with Jamil and Ruggie specifically since they all work in service in some way.
They are 100% the favorite student of the teachers, because of how hard they work both inside and outside the classroom. (This happened specifically after they saw the Prefect pass out, get back up, pass out again, and then apologize and go back to work.)
The Prefect probably has a cult. I don't know, probably. Or a fan club. If the Housewardens have a fan club, I'd think that one dude who came to a whole new world magicless, tamed a direbeast, beat 7 Overblots while magicless, and lives in what's considered a fucking haunted and abandoned house has a fan club.
They are THE heart throb of the school and they have accidentally acquired many sugar daddies.
Since the Prefect is probably physically capable, that's likely how the first years (except Ortho), and probably the entirety of Savanaclaw came to like them.
It'd be funny if the Prefect was like, talented in music, like both singing and dancing so Rook chased them down during the VDC auditions and Grim had to be like "HEY, HANDS OFF MY HENCHHUMAN!!!"
The Prefect is also the only reason Grim is being fed (fucking fatass).
They also, albeit to the dismay of all NRC students, get along with RSA students (Canonically, the Prefect in game has never looked down on RSA students either.)
They have managed to rizz Chenya, and then Neige when they met, and then accidentally rizzed up everyone else. Rielle was very easy to rizz.
I like to think the Prefect indulges Malleus's yapping sessions about gargoyles and genuinely remembers some of them, especially about his rants about grotesques.
The first years keep breaking into the Prefect's dorm to sleep over or to escape their dorm. Grim decided after their 4th break in to demand that they bring foods or extra stuff in as a bribery attempt whenever they wanna crash.
There was a war between everyone when the Prefect was deciding which club to choose until Grim just dragged them into that one big back club.
The Prefect sometimes visits multiple clubs just for fun and joins them sometimes. Especially the smaller clubs, like the Gargoyle Studies Club and the Muntain Lovers Club and the Light Music Club.
Jade drags them to hike with him almost every week, sometimes Floyd steals them away and drags them to watch him play basketball or someone else takes them.
Cater sends reels at 3 AM after they get really close and drag them out to eat cute desserts with him which is literally just him taking all the pictures and giving them all the sweets to eat. Neither of them complain. Free food is free food.
The Prefect has been invited into multiple group chats, including the Light Music Club one, and more.
The Prefect is the only person that willingly helps Lilia cook, other than the times the Diasomnia squad tries to salvage the cooking by directly helping Lilia.
The first years have this secret handshake that they keep gatekeeping whenever others try to copy them.
The Prefect is one of the only people that actually listens to Sebek when he talks about Malleus.
The Prefect genuinely scares others sometimes in a good way because they keep remembering small things about their friends for their gifts.
Epel sends you to Vil as a replacement sacrifice whenever he's trying to get Epel to do skincare. (Vil prefers this as well but he will never admit that.)
Jamil, Ruggie, and the Prefect has some GC together.
The first years have a GC where they keep forgetting to go to the actual GC and go to the shared GC with all the first, second and third years, say some wild shit and shocks everyone. (They once saw Epel typing some tarnation of a series of curse words because Ace stole his ice cream that he hid in Ramshackle.)
The Prefect did not fear Riddle, even before his Overblot because they don't have magic, so other than the mildly inconveniencing feeling of having a collar on they don't have any problems going on with being collared.
Most of the upperclassmen's crushes on the Prefect grew after their dorm's Overblot.
There have been MANY attempts of each dorm to have the Prefect move dorms (to theirs specifically).
After everyone basically had a crush on them, or just began to really like them as a person, the Ramshackle dorm's situation became very clear to them, so Ramshackle was fixed faster than in canon.
AKA: A person who is a genuinely decent, and sane person. (Shocker.)
