I love stem Chuuya! I also think he'd be good at things like firefighting, paramedic, emergency surgeon bc he is good in high pressure and emergency situations and has this need to protect people + he is good at following orders. Chuuya is the epitome of a knight-coded character to me lmao in a royal setting, he'd be a knight 100%.

With Dazai I'm not as sure hmmm I think he would be a GREAT lawyer, but I also feel like it's a kind of profession that could clash with his mental health. Would it fulfill him? I don't know for sure, but I know he'd slay in court lol. I can see writing and philosophy too although with philosophy, unless he was a professor (which I love!) the lack of structure and routine would make Dazai spiral if you get what I mean. Dazai is someone that I believe needs this golden middle between structure and freedom. Too much of either is risky. He'd be a good politician but, again, would end up just as miserable in the PM eventually. Maybe with the right people and team, he would enjoy being some kind of PR manager/ strategist or publicist hahah I think he would find it fun to manipulate PR disasters and scandals to make his clients look good. I could see him in the stem field too, especially in research! So as you can see I'm still not entirely sure no matter how many times I've had to find professions for Dazai :")
