Asta and some others get dragged on a training camp at a volcano by Mereoleona. Yami and Charlotte use an ability called Mana Skin and quickly get through. The other Magic Knights try to follow. However, Asta has no magic, so he’s unable to use Mana Skin. Asta gets a hint from something Mereoleona said on how he can get through this and he remembers what happened to him back at the Witches’ Forest.
