A childhood friend type—the dependable, empathetic sort you'd expect. She's genuinely kind and gets things done without fussing about it. Right now Sou's basically living at her place since his parents are never home, which works out since they're in the same class anyway.
She serves as vice-president of the astronomy club, taking the role seriously like she does most things. The thing is, she's got romantic feelings for Sou, though how obvious that is depends on how you read the situation. Either way, she's the stable presence in his life—the person who actually shows up.
