Albeit, not from abuse, Reimu clearly looks helpless here. So, I think it fits. Makes sense, I mean... can you imagine trying the danmaku like that?
Wrapped around that torii, she's got to be, at least, 35-40 feet long.
I don't think this belongs in the pool. While it's true that Reimu is sad and probably wants help, she's not shown in a situation where there's any sort of danger or desperation.
