@dragon3010 Didn't Berwick tell them that he's got more mana than all of them combined? That would be a one-sided fight with numerous fatalities. The second best solution, since they rejected letting Alpha take the lead would be to let Jean make contact with him. With anyone else, it's going to be fatal.
It appears to me that it's the nation of the number 2 magicmaster that is in league with Kurima, knowingly or not. Alus will know who their ringer is and that will become a fight to the death on sight. Not that turning him into ash will provide any evidence to clear him. Still, if he can get him to show that he's a shapeshifter, that will sway some people's opinions.
