A request came from the city government to ultimately clean up the strays in the city. Why did this happen ? There's case where yukkuri with sharp objects (glass shard, fruits knife, fork, art knife) is attacking humans, especially children.
Government will give the money needed, so they must do it perfectly.
Anon has thought of some well accepted methods such as the infrasonic device or the provocation method. But those methods are designed for closely knitted yukkuri community such as in the park or riverside. It's not as effective against yukkuri living alone in back alleys.
Right now, poison are used for it. Factory designed candy filled with chilli because no yukkuri can resist the temptation of sweets sweets. The candies are put in area where yukkuri might be hiding in.
Because the yukkuri live apart from each others, they can't learn from seeing how their brethens die from the poison and they can't take precaution.
Even then, there will still be yukkuri who survived the extermination. Add it to the large area covered, that number is still big.
Using the infrasonic is impossible. The device is too expensive and car can only reach streets. Increasing the volume will invite protest from the peoples so that's also out of the question.
Previously, Anon got inspired from meeting yukkuri. This time, he's going to Factory in the rural area to find inspiration.
There, he saw many Dosu captured and researched. There's Dosu fitted with tubes, Dosu that has became sloppy after being used to harvest sperm paste, and Dosu that's made to mass produce babies.
Dosu are rare and usually killed as soon as possible to avoid danger. But after the invention of the infrasonic extermination device, farmers can secure attacking Dosu and then sell them to Factory.
A spark of inspiration came.
Three months later, the Factory begin real world trial of the new extermination technique. They floated a big Dosu balloon proclaiming that Dosu has defeated human and got the very easy place with sweets sweets.
The balloon's hat is made from joining hat of many captured Dosu so other yukkuri will see that balloon as real Dosu. The words are of course forced by the Factory to the Dosu in captivity.
The method is a success. All the yukkuri in the city gathered to the stadium in hope of an easy place away from the hardship of city life.
The Factory workers waited for an hour before all the yukkuri gathered. Ramune gas is then released to put the yukkuri to sleep.
Part time workers begin to sort the yukkuri because they don't want any pet mixed in. In the end, there are pets who came here after being lured by Dosu's promise.
Anon thought to himself, tomorrow, those part timers will surely got muscle ache.
Of course this doesn't mean 100% extermination. There will be survivors, such as the lucky yukkuri who are injured and is unable to to to the gathering. But their numbers is minority among yukkuri.
This extermination is done during the breeding season. This way, for the rest of the year the population of yukkuri will drop rapidly because they can't replenish their number quickly.
Peoples will also keep on throwing away their pets, but at early stage the yukkuri will likely resort to begging passerby to be taken as pets, not a big problem.
Then there's also the immigrants, but the number is smaller than the breeding than could happen.
Even after his success, promotion and raise, Anon felt empty. When thinking of extermination method, he felt his life full of meaning, but now even abyuse felt unsatisfying, as if he had lost all his enjoyment in life.
One day, he met with the Mohican and they eat together. Mohican told his trouble because there's no stray anymore on the street he had to resort to producing his own. But raising baby yukkuri is difficult and take time.
In the end, Mohican doesn't want to bother the trouble and only abyuse baby yukkuri these days. It's not satisfying.
In his mind, Anon is apologizing to his comrades. It's his invention that made this situation. Nowadays, the only yukkuri on the street are the pets while majority of yukkuri avoided human.
Thanks to this, pet shop also stock less and less abyuse goods. Mohican told Anon, if there's just item that can be used by abyuser and lovers, everyone would get their Happyness~
Hearing that, Anon is excited again. Finally he found something to achieve. After thanking the confused Mohican and paid the bill, he embarked to make his next invention.
