Zenon has captured Vengeance and Yami, whereby Asta could not stop him using his brand new abilities. The standing of Noelle vs Vanica is still unknown and everyone would like an upgrade on Yuno.
Black Clover chapter 261 spoilers and theories really are forecasting which Zenon will unleash some of the devils in the world. That is no way a single devil will not leak out since the world tree magic was hyped around for such a long time.
Fans believe that the Black Bulls vice-captain will seek out assistance in Black Clover 261 chapter if all hope is dropped. Black Bulls VC will teach the other kingdoms about how to block the dim Tri Ad or even kill any of these most adorable mage people to postpone their arrival.
Black Clover chapter 261 might also reveal Asta becoming the blame for everything due to his own devil arm and getting straightened from the Damnatio and also the imperial Court again.
