Should Kyoukai And Ten Separate

Do you feel like it's necessary for Kyoukai and Ten to go their separate ways from Shin and start their own armies or will they always be under him?
Always going to stick with the HSU. Kyoukai has already made this clear even when she does become a member of the 6GG and I don't see any reason for Ten to want to leave the squad considering she said it was her dream to Gaimou to always be with Shin and then find her "own" happiness which I would assume is assisting him in completing his dream.
