Though seriously Reimu again? can't it be Marisa going unfaithful or something? i recall the time when both could go wrong in equal ammounts screwing up the other, but now it's all deibus, it makes me feel like they are glorifiying a bit the Marisas.
Hmm, maybe we could start applying the stereotype of the bad, drunk and violent husband that beats up her wife for the silliest thing and without any good reason aside of being a chauvinist douche?
Now that would be an interesting Take "Wife Beater" Marisa, think about it people!
Nope, Deibu isn't that stereotype, she needs to be a "husband" to be that, not a "Wife" like she's, she's a wife, so she's just the token negligent, lazy ass, pampered wife. If anything she's like that fat woman from that Comedy of Eddie murphy about the abusive wife and shit, but it isn't the "Wife Beater" stereotype.
Marisa fits better for the Wife Beater, since, well, Marisas are always the husbands, and their Bawiza self are usually the kind that sometimes screw around and leave or use their family as bait to run away. And they are also willing to harm their families if they make her angry, so i think it would be nice to exploit that a bit more for future stories.
