Black Clover arrived in Chapter 245 and explained Yami's amazing story and action. Yami did a good job of saving people from Dante's attack range. No doubt he has to deal with Dante where Dante himself is still dealing with One.
Gravity Magic
The link between the normal world and the world of Devils
Dante himself said that if Yami was the link between the normal world and the world of Devils. Then what will happen with Chapter 246 later manga? It is likely that later Asta will meet the devil and will be the turning point of this story arc. Dante who was hit by Iai from Yami would use a healing magic called Lucifero. Eventually he will be able to rise again and fight Yami again. Not to mention the complete plan of Dante and his party will be revealed in Chapter 246.
In the following chapters it is also likely to be revealed that Yami and William are bridges to the demon world. Chapter 246 manga will be released on April 5, 2020.
