Sanae is a slut, but Reimu is a mass-murder (Touhou in general...), juvenile delinquent (Beating up children and retards in EoSD), thief (Looting Mayohiga), religious fanatic (She oppresses other religions!), preventer of academic progress (PoDD), enemy of free speech (Beating up journalists), supporter of evil (Stalling Marisa in IN. No, it doesn't work in the other direction. Marisa had AWESOME MOTIVES: Being an asshole), etc.
So, yes, Sanae IS a good girl, when placed next to the Satan That Is Reimu.
Thanks for the exageration Shanghai Alice, now back to how touhou really is Reimu is a good girl and Sanae is a good yet many times mistaken girl, the Sanae Yukkuri is as much neutral and the Reimu Yukkuri in general is bad like Marisa and the majority of the ultra common yukkuris.
Sanae Fanboy? lol i prefer Reimu, but it's a clear fact that the YukkuReimu is usually portrayed worse than the YukkuSanae, of course, that doesn't mean it's a Yuka level of Yukkuri Saint, hell, so many shithead Sanaes, like the ones that rape YukkuKogasas.
And that line of yours of Reimu was taken from TvTropes, as "alternate character interpretation".
Honestly Shanghai Alice, make OYP a favor and do not talk about Touhou, nobody should, we are here for yukkuris, yeah, they were spawned from Touhou, but i doubt anybody here really wants to talk about Touhou outside of "this yukkuri is probably derived from -insert touhou character name here-"
I really don't think that we should discuss further our opinions of Touhou here, just our opinions of Yukkuris.
