>>49792468>>49792443We've talked about this before, but I feel like Reimu and Sanae act very sisterly towards each other. Reimu's more hotheaded and warlike, but acts less mature. Sanae looks up to Reimu (by her own admission) and thinks she can learn from her, and is calmer.
They butt heads a lot. They rub their successes in each other's faces, but you can see there's no malice behind it. They're friends, Sanae is around Reimu a lot of the time, and they certainly don't hate each other.
I might've said this before, but if I knew nothing about Touhou and you told me how these two act towards each other, I'd tell you that they're sisters.
