Reimu is an oddball, really. Her canon attitude towards incidents is just flying in random direction since her intuition and nature itself (one time she walked over a river without noticing because fish formed a road for her to walk on with their bodies. well, she is rather "carefree" and oblivious) would lead her to the culprit ANYWAY... To be honest, at such rate Heir works for her as well.

I really need to get more into Touhou, I absolutely love every single bit of lore.
