Why, what did Marisa do? She's just a pimp, and other yukkuri are drawn to her. The worst thing she did in this series was refresh with Alice, but Alice consented. This Marisa was also willing to support two families. Hell, with the Patchu, she probably could have formed a great yukkuri empire.
Oh wait, that's why you guys hate it. Scared of a little yukkuri, are you?
Tricky circumstances, I suppose. The Marisa was willing to take responsibility, but she clearly wasn't keeping the Reimu's emotions in mind. She's not blameless, especially in regards to damaging others' feelings, but she was otherwise acting to the best of her knowledge.
Of course, it's easiest to just blame Alice. Alice ruins everything, including a budding Empire of Ease which would, ironically, crush the world beneath its easy iron Yukkbottom.
Reimu was kind of a bitch, but with the prevalence of rapist Alices, her attitude was, while not justified, at least understandable. In the end though, the whole thing was Marisa's fault.
As much as I like yukkuris, I just want to slap the hell out of that Marisa.
From least to most responsible for this startling tale of human frailty, I would say...
5. Patchyukk. Just showed up to help gather food like a servant. Only wound up rollin' with the Yukkurisa because of perceived circumstances. 4. Yukkureimu. Jilted mate, was there first. 3. Yukkalice. Offered self, kept the murderball rolling. 2. Yukkurisa. Took the bait, took Alice home without regard for Yukkureimu's feelings. Had good intentions, but grossly misjudged others' feelings. 1. Alice. Non-Yukkuri Alice. For reasons that do not need explaining.
she took in more yukkuri despite the fact that she would have to work even harder to take care of them, I guess in the end she just wanted them to take it easy despite her actions, I have a very neutral feeling about this thing
At least the ants will take reservations for the winter.
I am rather surprised this type of stories, it is like a slap in the view that we dislike to suffer the Yukkuris but also relieves us the blame when we see a shithead yukkuri receive their well-deserved, this end would have been better if a Remilia appeared in the entrance of the cave ready to eat
For all those of you who are saying that Marisa had "good intentions": she wasn't smart enough to have good intentions, and "intention" doesn't justify her actions.
Marisa seemed to have pressured Alice into refreshing (because Marisa was the one who took the initiative) and Alice thought that Marisa was single.
Reimu thought that Marisa was cheating, and Reimu thought that Marisa betrayed her.
Furthermore, despite there being an obviously tense situation, Marisa just left the house to go hunting.
Reimu could have seen Alice as a rival who would steal away Reimu's food, because there's no way that Marisa could have gotten enough for all those koyukkuris - especially as they grew up.
On the other side, Alice was punished for refreshing with Marisa, because, if you look closely, Marisa lied to Alice. Marisa said that it would be her first time, but after refreshing, she admitted that she did lie, and said "Actually..."
Reimu blamed Alice because Marisa left, and she needed someone to vent her anger on - her belief that Marisa would not cheat was so strong, she thought that Alice must have tricked Marisa in some way. That doesn't make it right, since Alice only refreshed at Marisa's suggestion, and only stayed in the house at Marisa's pressuring to be one big family.
While the koyukkuri are in no way at fault, they are the product of refreshing that wasn't supposed to happen.
Still, Alice isn't perfect; even as her koyukkuri died, she refused to defend them (seemingly believing that Reimu would stop) and then when she did defend herself, she attacked the weaker koyukkuris, not the root of her problem - Reimu.
When Marisa got home, she refused to listen to Reimu's perspective, and punished an already injured yukkuri even though she didn't actually know if Reimu killed everybody.
There were obvious hints that Marisa shouldn't cheat (ie Marisa was ashamed of admitting cheating to Alice, and Marisa was sweating while Reimu was crying out foul play) yet Marisa still went and got Patchouli.
Marisa shouldn't even have hooked up with Patchouli; it wasn't raining, and she was supposed to be focused on gathering double the food for double the family.
She commanded Reimu and Alice to take it easy, but she ignored the fact that taking it easy was so easy, simply because Alice was too pressured to fight back, and Reimu did not fight Alice.
And yet she was the one who got the happy end - Patchouli did not even put two and two together, even though anyone could've realised that Marisa had two spouses.
