Oh god... That was quite... something.

Oh, now the ending makes sense. Marisa managed to leverage Mary's ability to cross the border with Renko to allow her to come back to Gensokyo once she'd gotten what she wanted from the outside. If you go by the theory that Yukari is a post-human Mary, her comment makes sense since only her power and Reimu's can make a hole in the barrier to pass through.

Well, that was interesting.
Is there any particular reason why Alpha is spelled Alfa in the title?

Soo, did the (Gensokyo) Marisa And the (outside world) Marisa managed to “switch” places with each other’s? (And why the afterword meant by this was the “climax” of a story? There’s more into this story that has something to do with the other Marisa’s too..?)
