Sasha's a funny one. Despite Sasha and/or her redheaded friend seemingly being on hand whenever the MC is in jeopardy, most of the interactions between her and the MC point to her ultimately being on the lookout for her friend Robin, not the MC. Something negative happened between Robin and Bella in the past that Robin wants to make up for, and Sasha seems to be helping her achieve that. Sasha's attitude to the MC is affected by (a) the MC's relationship with Bella, and (b) how the MC treats Robin. So far, the MC is simply a means to an end.You know, I've been wondering lately if Ayua and Sasha have been asked to keep an eye on Nami and Nika respectively. Sasha is always lurking in the background of quite a few of Nika's scenes, an Ayua seems to be keeping somewhat close to Nami. Why that is, I'm not sure. Are they observing? Protecting? Sasha and Ayua are both accomplished in self defence...
Ayua/Nami - that was Marla's doing. She paired them together for the college assignment, just like she did with the MC/Bella.
