The main points of the story's first half seem to be:
-Yukkuri are preparing for winter. -Dumbass pair(or just one against the other's will) make babies. -One of them goes to a human village(possibly to beg). -Anon feeds the babies sugar water while they're still on the stalk. -Once they're born they vomit up anything they try to eat.
Well, after a motivational seminar in the office, I hate that Deibu even more.
So, why is the meal brought by Marisa is not enough ? That's because Marisa is not working hard enough. If she work hard enough, there will surely be enough food isn't it ? But because Marisa is a good-for-nothing, she doesn't have any right to eat. Yes, it's not like Deibu asks too much or too greedy. It's all because Marisa is lazy.
marisa is good stray yukkuri anon take her and destroy deibu nest why because deibu is bad wife for good marisa. them later marisa turn into bodied yukkuri and she wake up she lost memory about her bad family but she still good yukkuri.
