Hmm. Since this was already necro'd, I suppose I'll add my two cents.
1. What is the 'censor' bar blocking out? I don't think its a curse word, cause that would seem odd in context of that line.....
2. Yuyuko shouldn't kill that mother, It may have lost the will to live, and its sanity, but It can still be used to make more kos! So it can still make more food! XP
that's kinda why i hate the whole "kill and torture Akyuu" since it's as you say rocketcochon, a fanwork with a out of characters interepretation of that character.
yet somehow people love to miss the point, even when many aspects of touhou are fan based, there are some obvious limits about what to take serious and what to take as "OOC".
