Alright I think I've figured out who runs the Blue Homeroom. For reference, this is for the students who just want to have an ordinary life (or what passes for ordinary where they come from). The reluctant heroes and villains, or those Isekai'd into places that really just want to go home, or the ones who for various reasons aren't allowed to pursue a normal life (such as X-men due to discrimination). For them, the Summer School is kind of their chance to be normal.
I think the perfect Homeroom teacher to bring balance to these kids is:
Obi Wan Kenobi (Star Wars)
This Jedi Master has mentored two students, both Skywalkers, and you can tell when he was training Anakin he was trying to reign in his over adventurous tendancies, just trying to follow the rules of the Jedi.
Given his Jedi training he'll be able to handle most of what his students might throw at him, as well as be able to calm them down with his force powers in rare cases that would be necessary. He is also a fountain of wisdom and a rock of stability the students will be able to strive to be.

Now that he's in here, I just need to think who would suit class Red. This is the class that's drawn to adventure, actively seeking out risks and chaos to achieve their goals.
My first gut instinct is
All Might from My Hero Academia-he's a hero who runs towards danger, and danger is drawn towards him. I'm just not sure he would be able to handle a class of chaotic and chaos drawn kids.
I'm also thinking
Uncle Iroh from Avatar the Last Airbender. He himself is not hot headed, but he's used to giving guidance to various adventurous minded students, from Zuko to Toph and even Korra later on. Might even have him come in Spirit Form, giving him an extra level of protection because he's already dead, although those living muscles are a terrifying weapon themselves.
The final idea that comes to mind is
Wolverine from X-men. Not anyone's first thought of a mentor, and likely very reluctant. However, there's no denying he is used to danger coming towards him, and can survive basically anything the students can throw at him. He's also a surprisingly good teacher, who cares about his students. He probably has a lot of knowledge in his adamantium skull, assuming he remembers it and can be bothered to share it.
I'm leaning towards Iroh because I feel he could teach students stuff outside of just combat and heroics. Like
Ikuto Tsumura and
Chiyuki Fujito the main characters of
Smile Down the Runway I really don't think Wolverine would be able to help inspire them to pursue their dreams of being a fashion designer and model respectively.
What do you guys think? Is there anyone you think would be a better alternative for Class Red's homeroom teacher?
