Kusa and Kiri could've made a deal. In order for the Nenshou to learn the secrets of the Hozuki's ultimate power, if they could learn to turn themselves into acid, the Hozuki anyway. They make this agreement, and send representatives to Kiri. These Nenshou, maybe five would include Karei, as she was recently upgraded to Chuunin. And for the next five years, they swapped info on the repsective techniques, and training in their very basics. And then, basically after the five years, they went back to Kusa with the info on how the Steaming Danger Tyranny tech worked. And within five more years, Karei perfected it.


 * My idea at the moment. This leaves Kiri with potentially Hozuki who can turn particular acidic.
