Reimu Hakurei : Murderer of Youkai?

[Drake]

Or the former likelihood of Yuyuko just trolling Youmu and Mystia.

I one thought of a bone flying out of nowhere and Yuyuko eating it, but it sounds too meeh

shinki went back to makai, after all. speaking of which, Zun missed a great opportunity to bring her back in Touhou 12. She could've replaced the midbosses of levels 5 or 6.

Whaaaaat
Shinki would be like Phantasm boss. Yuki and Mai can be her midbosses. Yumeko can be Extra boss. Nue, get out.
Oh, and Luize can be Yumeko's midboss. Just because I love her.

I'll stop fantasizing now.

However, the Hakurei maiden had defeated the vampire of the Vampire Incident to stop the youkai rebellion.

That's a mistranslation in the wiki.  It was actually "powerful youkai" that beat the "vampire" in the Vampire Incident, not "the shrine maiden" in Reimu's Perfect Memento section.

The correct translation (a youkai(s) defeating the vampire, NOT the shrine maiden) removes the contradiction.

Even if the shrine maiden didn't beat up the vampire, the youkai who didn't like the original contract came to discuss it with the shrine maiden. Again, this was still a few years before EoSD. Even though the shrine maiden described (tired of no shenanigans) sounds like Reimu, I still have to wonder.
