to be honest if we're adapting DE to touhou as such then reimu is an odd pick. sure, she's the "cop," but the similarity ends there: she's closer to a kim, not a harry. she upholds order well, despite the foibles of her job; she's decisive on the job, though she doesn't want the action of an incident; she's archetypicalized as a sort of 'saintly' figure, for all her flaws. harry was a superstar cop- he was good at what he did, but it was a function of his flamboyance and willingness to be the Can Opener. he pushed people around. he got into nooks and crannies. he did copious drugs to support how he was burning the candle at both ends
now if you want to find someone who upholds the systems of Gensokyo voluntarily, who thinks that might (at danmaku) makes right (i.e. power), who solves incidents on her own merit and consumes copious drugs(*This is the author's personal interpretation.) to keep herself going?
