I actually love how this artist depicts the relationship between Reimu and male-ified Marisa. The plot of the related doujin is (post #2783158), Reimu wakes up to Marisa and others becoming dudes one day, and she is horrified and wants nothing to do with male Marisa because she is still gay. Yet there he is, going for a kiss every chance he gets like nothing's changed. I think in the first two pages she breaks his hand for it. It's a hilarious deconstruction of genderswap fiction.
