Is top left a reference to other Takumi stories? There's actually continuity in the Takumiverse?
I'm not sure. The first two abuses look rather common, but the face rip might be a notable reference to other stories. However, that is the reference i cannot remember.
WoW! The Useless Father Marisa is too nice even if useless, the Mother Reimu needs to be more tolerant, and the scum Koreimu deserves what would have happened to her.
Well, this Miss(?) has appeared already a number of times, so even if the panel isn't strictly referencing an old story, there is still some sort of continuity in recurring characters
