Too bad, Marisa. You don't like Mister's food, get used to compost. Look at that good Reimu! She accepts compost and helps the environment by reducing waste! When you start to accept compost MAYBE he'll give you good food.
(Good End: Marisa recognizes the error of her ways and learns to respect Mister's efforts to feed her. Marisa and Mister take it easy.)
(Normal End: Marisa learns to accept the Compost and her new position in life. She has babies with Reimu and they take it easy eating Mister's compost (ko's don't mind because that's all they've ever eaten).
(Bad End: Marisa wastes away in the Compost bin, refusing to eat the compost. She is later eaten and shat out by Reimu, who proceeds to take it easy.)
I would prefer Normal End, due to the unlikeliness of Marisa recognizing her actions. Also, it's a ko. It can be easily influenced to accept it's new conditions with a little prompting and heavy brainwashing. I've seen it done before. In fact, that's probably how that Reimu ended up the way it is.
Well it's abuse, there are no victim or innocent yukkuri around that are being avenged and later get to take it easy after the shitheads were killed or something, so i doubt there will be a good end.
It insulted Mister's food. I endorse this type of punishment, and I still say brainwashing is the best method. Anyway, aren't yukkuris whatever you want them be, having no solid canon, only preferred ways of being?
The fanon kinda counts as cannon, and there is also what the authors wants the yukkuri to be like. So "yukkuris are whatever you want" has some limits, specially for "if interpretations" that go against what some author's intentions.
Not in this case of course since there isn't much of that, but it's good to know that about "yukkuris are whatever you want them to be", some people take it a bit way too liberal or even with their own agenda to spite on a particular group of the fandom, so it's better to remember that it has limits.
Well, it's a bad idea to go around trying to set up these justifications and different alternate "good endings" on abuse; regardless of motives, it's setting up the same thing to happen on family friendly (glorious possible abuse ends and all) and giving the impression it's alright- which will get very messy. People don't like it if you mention a 'bad'/abuse possibility or ending in FF. Or at all, really.
Yeah we already had a few ultra wacko abusers that DID want to do such things even with the rule on, better not give ammo for any of those going "well if that guy does it on abuse works, i'm doing it on family friendly!"
