Black Clover is gearing up for the first major phase of the manga’s final arc overall, and the newest chapter of the series is setting the stage for Yuno’s key role in the Judgment Day final holy war for the fate of humanity! The final arc of the series has gotten off to an explosive start as following the fights with the Spade Kingdom’s Dark Triad, Lucius Zogratis had finally made his move on Asta and the Clover Kingdom. With this first major display of his terrible new power, Lucius has now declared war for the fate of humanity. But he’s keeping a close eye on one particular fighter as he moves ahead with his plan.
Asta has been taken out of the equation for now following his loss to Lucius and the brainwashed Sister Lily, and this has left Yuno and the rest of the Clover Kingdom trying to figure out how to proceed. Though Yuno is fully prepared to dive into the battle in order to make up for Asta missing from action, on the other side of the battle Lucius is also keeping a very close eye on Yuno as Lucius believes that Yuno will ultimately be the one that will bring any kind of chance of victory for humanity’s side.
Chapter 336 of Black Clover sees Lucius getting an update from Adrammlech about the supreme devil’s previous fight with Yuno, and it’s teased that Yuno had greatly increased his power in a surprising amount since the fight with the Dark Triad fifteen months ago. Lucius then confesses that out of the “tens of thousands” futures that he was able to look into, only one gave the Clover Kingdom an advantage. It’s one that heavily featured Yuno as the key to making it happen, and thus Lucius has declared that he will crush him specifically to keep that future from happening.
