Mei and Cammy thought about it before they spoke between the two of them in their own special language before facing the others and nodding "I believe it is possible that the aura read pokemon like us differently to others. While my sister and Gileta have no Berserker gene within us, the aura marks us as regular pokemon but towards Pokemon like you and the others it reads differently. However we have an idea as to how to counter this, the only thing we ask is that you don't repeat this to anyone" Cammy said though she did end up with a minor headache as trying to remember her life before reverting back to an egg in the explosion causes her pain. 

Mei was on hand to hold her sister hand before she continued for her. "I remember a special flower known as the Auravalls that could probably perfect the serum and cure the berserker gene, however it only grows in places strongly connected to the aura, these area are guarded by powerful Lucario's who connection with aura is far more powerful then any other Lucario in the world, however due to the pouchers and others who carry ill intent. These Lucario hate and dispise of Humans epically trainers. Mike did some looking into things for us and their are only three places in the world where these flowers can grow. The Cavern of Auralda in Galar, The cave of Lucardo in Sinnoh and the Mountain caves of Rida in Unova"
