Once you’ve chosen your house, you’ll have access to characters from that house you chose. But that’s not all, you can also recruit students from other houses and other characters, with a few exceptions – you can’t recruit the house leaders. And some characters will only be recruited once you reach a certain point in the game and you’ve got a better support level.
If you want to recruit other students, I suggest to use your free time at the monastery to explore, chat with them, return their lost items to them and give them gifts. That way you will build better support level and you will have a better idea of who you want to recruit and what you need to do.
Three things are needed to recruit someone: specific skill level, specific stats and better support level between you and the one you want to recruit.
