As the uneasy Anti-Yukkuritis spread, Popular Marisa quickly produced her "Magical Medicine from Dosu" and used it to treat many of the little ones.
Even some adult yukkuris who feared coming down with Anti-Yukkuritis began to ask for the medicine. Popular Marisa distributed the medicine to everyone, and the spread of the Anti-Yukkuris was quickly halted.
Because of Popular Marisa's cure, the epidemic was not discovered by the caretakers and overseers at the Adoption Center.Things took a turn for the worst again quickly though. The quality of the Mister Food continued to decrease. Even though a yukkuri could enduring for quite a while after having a dose of medicine, even more cases of Anti-Yukkuritis began to appear.
Mother Reimu's family was no exception. Everyone stayed quietly in the nest every day. The normally easy attitude had completely vanished.With the Magical Medicine almost gone, Popular Marisa felt the severeness of the situation. One day, just as she was stewing over things, a Yukkuri Mystia flew by the yard of the Adoption Center, and in view of all the yukkuris, gave Popular Marisa her orders from Dosu:
"Dosu will now punish the uneasy Mister Humans!"According to Mystia, Dosu had long been in negotiations with the Mister Humans. Her terms were that as long as the Mister Humans became slaves to the herd and brought everyone lots of sweet sweets every day, Dosu would not punish Mister Humans.
But the Mister Humans insisted on being stubborn and would not accept Dosu's compassion. Instead, they even were threatening to punish the herd! Dosu was enraged and effortlessly drove away the representative of the Mister Humans.
Now, Dosu had given her orders to begin the assault on the city. Her commmands were for Popular Marisa to immediately recruit the yukkuris at the Adoption Center into Dosu's Army. After three days, everyone was to meet in the fields outside the city and there begin the FINAL BATTLE against Humanity!
