Summary: 2 days after Mecha Reimu was 'born', Anon starts. He trolls Reimu, speaking through Mecha Reimu telling her how Marisa is seeing the Alice next door, and talking about how Marisa said that she would divorce Reimu for Alice instead, being QUITE explicit.
Reimu goes into a rage and attacks Marisa, but since Marisa is stronger, Reimu gets beaten up more, and now the two are on bad terms.
