I'm thinking that the "anko####" tags are really unnecessary, because they are usually only used once. Basically, every time a new story is written it gets a title picture, just like a novel has an illustrated cover. I think the tags "anko_story" and "with_story" would be better suited tags.
I would agree, but I'm pretty certain I've seen more than one picture using the same anko**** tag. That ought to be enough to justify numbering them in such a way.
Furthermore, numbering them allows those of us who read the stories to check for pics that go along with them more easily, like an index of sorts.
The illustration tag works the same as the anko_story tag that you mention (although not all stories are anko stories), and then they split down into each individual one, like anko1226, anko625. I want to be able to find each individual story, rather than going through the whole pool.
Story starts with a leader Marisa delivering a cage of shitheads to a human, satisfying his 'quota'. We get a back story of leader Marisa, how her parents were initially taken to meet the quota, resulting in her sisters' deaths when they couldn't feed themselves. Then again with a Patchouli who took Marisa in. She eventually became leader, but when Anon is taking away a Reimu who had little ones, she gives herself up instead.
Leader Marisa demands to know what a 'quota' is, and Anon explains it to her, how the actions of shitheads resulted in 'exterminations'. Since they can't tell shitheads from normal ones, they usually take any parent they see to meet the quota. Realizing what he wants, leader Marisa leads Anon to the nest of a scum Marisa she turned away before, exchanging her life for it. Anon later suggests the idea of having leader Marisa and her clan hunt scum yukkuris for him.
There was one time when they failed to meet the required amount, forcing leader Marisa to sacrifice a retarded orphan Reimu. The clan thanks Reimu, who can't even say 'yukkuri' properly, and this encourages them to do an even better job. Still, leader Marisa is constantly stressing over having to meet Anon's quota.
Later, a young Marisa shows up, claiming that she wants to become like leader Marisa. She performs admirably, but the only thing holding leader Marisa back from making young Marisa leader is the fact that she keeps telling leader Marisa that she should use her authority more despite leader Marisa telling her that she's wrong. Leader Marisa decides to have her friend Patchouli become leader instead.
After the two Marisas take down a Myon, young Marisa brings up the matter again, but leader Marisa turns her down. That's when young Marisa backstabs her and kills her.
She tells the clan that the Myon did it, and asks Anon to recognize her as leader, giving herself much more authority than leader Marisa had. She soons shows her true colors, sacrificing some clan members she doesn't like to meet the quota, bringing in a Reimu, Marisa and Alice scum bunch, as well as releasing some scum yukkuris the clan has captured.
Things come to a head when a Reimu who said it was weird that her captured scum got released winds up dead. Anon, who is already suspecting after hearing his 'scum' yukkuri protest that they haven't done anything and the young Marisa saying that the quota is 'easy', comes in to talk to the clan. Despite their fear of him, Patchouli and her aide Chen manage to tell him what the young Marisa has done. Anon figures out that leader Marisa was murdered by the young Marisa, shocking the two.
Young Marisa comes back, and Anon confronts her about the releasing of scum yukkuri. She promises not to do it again, and asks that she be allowed to continue as leader. He refuses for two reasons, one being that she murdered the previous one (he makes her confess in front of the clan), and the second that there is a better leader, Patchouli. Though she knows that the quota is uneasy, Patchouli accepts, and orders the clan after the escaping scum.
The Alice has her eyes stabbed out by a Marisa whose family Alice either raped or threw away as 'scum', but is stopped by killing her by Anon, who switches her out with the non-scum in the cage. The same goes for the rest of the scum in the clan, the last one being the young Marisa.
Initially in disbelief about being in the scum house (the yukkuris' name for the cage), she tries to beg for her life, saying that she did her job fulfilling the quota, even swearing that she won't ever return again as long as she lives. But Anon adds that there's now a third reason why that won't happen. The way leader Marisa responded to Anon whenever he asked her about the quota and the way young Marisa responded rubbed him in different ways.
Young Marisa isn't stupid, she knows Anon won't ever save her.
Later, Anon meets with a Patchouli who has finally gotten used to him, and while she has met the quota... the scum pack are still in the cage, the clan purposely catching more than the quota so they can keep the scum inside the cage, especially the young Marisa, whom they hate for killing leader Marisa.
Young Marisa asks Anon if it's finally her time to be taken away, to which he replies in the affirmative. But Chen suddenly comes up saying that they've caught one more. Young Marisa's torment will continue for a while longer.
"Mukyu, quota is uneasy." "Yeah, but... not meeting it is even more uneasy." "That's right, quota, quota, mukyu." "Yeah, can't take it easy with a quota."
What a great story, and I like this method of culling the bad elements out of the yu clans by filling "Quotas", It sure encourages the Yu to pay more attention and be less naive about their scum fellows.
