Black Clover Chapter 43

A spatial magic portal opens inside the cavern, bringing forth a strange newcomer who easily bypasses defensive spells and pins Asta down. Sister Theresa steps in with powerful flame magic, revealing her past as a former magic knight and her connection to Captain Fuego-Leon. Meanwhile, the newcomer administers a strange liquid to a defeated captive, causing his magic and body to warp into a towering, monstrous creature that loses its personality while growing overwhelmingly powerful. As the mutated beast rampages through the underground space, Asta and his allies prepare to defend the frightened children from the sudden onslaught.
