Well the goal isn't necessarily to have them become friends right off the bat. It's more that they can learn a lot from the pairing.

Kotaro/Akari - learn to handle conflicting ideals.

Saya/Suzume - building a rivalry. Once Saya realizes Suzume is trying to surpass her, she will have motivation to not allow it and probably do some gentaijutsu to take it a step further (Suzume would have her eyes for her extra).

Seina/Satori - not sure, but I can see some amusing interactions between them based on their personalities. I guess Seina could get used to people she's not used to dealing with?
