First of all, please please please make Kiza the leader. I don't want Toxic to lead because I don't know how ;-;
Also, can I make it so Sylvia's whole family moves into the building of 1-A (a special medical room almost akin to Recovery Girl's office) for medical purposes? Sylvia's in critical condition, Jack's an elite student, Kouki works there, and Lucy would be homeschooled by Kouki for that one year before joining in the next. It also gives Lucy more time to communicate and interact with Class 1-A, as well.
Plus, in the manga, Class 1-A was easily the closest dorm room to the school, making it so much better for Sylvia's condition. How does that sound to you all?
