FINALLY HERE ARE MY ANSWERS
Akihiko: Absolutely mimi. I feel like mimi/akihiko is such a good matchup because akihiko has such a tendency to fall for people based on surface level perceptions + mimi who doesn’t let anyone know him beyond surface level perceptions. I feel like they would make an amazing celebrity pairing where people project their own ideals onto their relationship. Does this make sense. I also feel like he’d want to be like lucius in the same way he wants to be like mikio
Hatto: Him and silver need to meet asap like just because I want to see the carnage of it all. Mimi changing his persona and acting like miyu around him would be a wonderful idea as well
Himawari: I definitely have to say mimi again because hima loves having a senpai to look up to and I feel like mimi could fill that role for her. Mimi is so versatile on the surface
Kain: I kind of think yura and kain hanging out would be really funny because they can totally study together but I also feel like kain is just too energetic for yura’s tastes. I also want kain to meet silver because she would cry at how tall she was compared to her
Katsu: Katsu/mimi is so fucking incredible. Like I just love imagining their dynamic. I want him to meet ruruka as well so badly. And delta as well due to her similarities to mikio. Also lucius becayse I feel like he would instantly get some mikio vibes from them
Ken: Definitely yura I feel like they would get along so splendidly. I love it when two straight man persona characters are paired up together. I really loved the idea of him and lucius meeting too from your answer like it looks like an unexpected combo based on appearances but it’s really really good
Kokuhaku: Yura as well like I feel like ken kokuhaku and yura talking together could have some hilarity.
Maki: I fucking need the Yuma/delta/maki collab to happen right now like it would sell a hundred bajillion copies I’m serious
Mikio: MIKIO AND DELTA MEETING WHEN. I kind of want to see what mikio and lucius would discuss together too
Mitsuharu: Lucius and mitsuharu definitely see eye to eye with each other. Based on appearances too I also really want mikhail and mitsuharu to meet idk I think it would be good
Shin: I have always wanted to draw yana and shin together like the matching buns I love it. The idea of mimi and shin and akihiko all hanging out and mimi teasing akihiko in front of shin is kind of beautiful to me
Shinju: Yura and shinju drinking buddies is such an incredible concept this is like also something I want to draw. Them drinking across from each other in a kotatsu
Tomoe: This might be crazy but I think tomoe would LOVE delta like not only does he get along well with yuma but he’s fucking ourple. She would go crazy over him
Yoshiyuki: The delta yoshiyuki dynamic is so fucking good and I also want him to meet silver. Like. I just think it would be so fuckjng funny. I just wanna see what would happen
Yuma: Do I even have to say it. YUMA/DELTA SO BEAUTIFUL
