I don't remember every single episode or chapter title, okay?

If you study at Karasuno, then you know what happens. Either way, you have to convince Nishinoya and Asahi to join the team again

If you study somewhere else, then you either aim to be future ace or guardian(or great defender) of your team.

(Note on the second one: If you're friends with one of the Karasuno team, then you also have to try and convince Nishinoya and Asahi)
