Black Clover is teasing Asta's full Devil Union transformation with the newest cliffhanger of the series! Black Clover's anime might be coming to an end soon, but Yuki Tabata's original manga series is really hitting its stride as it is making its way through the second major phase of the Spade Kingdom arc.
