From what I recall, my character (Saizo Yumizuru) will be a member of Kiri's higher caste, while the other two teammates are lower caste. So those two would have to go through the Academy fights in order to become Genin.

I currently have it said that the upper caste of students didn't have enough to make full three-man teams, and would need to use lower caste students to fill the spots. My guess would be 10 upper caste students (3 teams and 1 lone student)

But the students didn't want to be teamed with lower caste, so instead of having 1 lower caste for every 2 upper (5 teams total), they just decide to "sacrifice" the extra upper caste student to be on a team with 2 lower caste. Saizo is made the scapegoat and ends up with your characters.
