Her personality is straightforward, optimistic, and a bit curious. She's quick to anger if offended, but just as quick to offer help to those in need. According to [[Komachi]], Reimu has an innocent heart that can't truly hate anyone.<ref>''[[Wild and Horned Hermit]]'' chapter 5</ref> While rather lazy in her free time, she's highly devoted to her duties as the [[Hakurei]] [[Shrine Maiden]], resulting in a "shoot first and ask questions later" attitude to youkai extermination. This makes her known to exterminate youkai indiscriminately, regardless of how much of a threat they represent to her or others. One example is [[Tokiko]], who was ambushed by Reimu while she was, in Reimu's own words, "reading and minding her own business".
Apparently, however, she actually helps youkai in trouble when it really matters. For instance, in ''[[Silent Sinner in Blue]]'', she kept [[Reisen]] (disguised as an earth [[youkai]]-[[rabbit]]) at her place to help healing her injuries, giving her the futon she uses to sleep and even going to [[Eientei]] to inform its residents that a wounded rabbit was at her shrine. She also treated [[Shinmyoumaru Sukuna]] well enough after the events of ''[[Double Dealing Character]]'' that the inchling gave her a matching kimono as a sign of gratitude. Since it was so small, Reimu had to wear it on the back of her head.
It has been stated that Reimu treats everyone the same, whether they are humans, youkai or gods, giving them no particular respect or disrespect. This habit has caused her to inadvertently befriend many youkai she defeats. While she tries to keep youkai away from her shrine, this is because it makes it harder to gather faith from humans rather than because she dislikes them. At the end of the symposium in ''[[Symposium of Post-mysticism]]'', when Reimu goes to break it up, Miko notes that though Reimu says she wants to eliminate all the youkai, she actually just wants to attain a peace in Gensokyo that doesn't require violence, like the others present wish.
