Onee-tama is such a troll, pairing Ayane with Yukari XD
Hayate is pretty much a given considering Akira said she would make sure she'd take part in it, but yeah, have to wonder about her partner. Would be fun if it's her twin, yeah. Though she's new around, never took part in hoshitori and it seems they used the student DB to decide the pairings, so that alone might rule her out as they probably don't know her skill. Well, unless they took data during the graduation event.
