Shithead Marisa is the child Marisa with the piece of stalk, in the third panel. I wonder how the rest of the children were eaten, I would like to think that Shithead Marisa was the next one in being eaten... or the last one, considering how tolerant was Reimu during all the ordeal.
Reimu was angry because she thoght that Anon came back home later than promise(1week) But the real is the shithead komarisa destroy the pile of stones that parent yukkuris set to count the day on day 3 then parent yukkuris thoght that Anon would come back on day3 and so angry... yes because of beanpaste brain
The original koreimus are not shown. As of now the ko-komarisa and ko-koreimu are trapped under the food dish, and a ko-koreimu and the two original komarisa are trapped out in the cold.
