Descendant of the Wizard King

Mark is an everyday wizard trying to soar to great heights using his magic. However, he can't seem to use it correctly. But one day, after his village was attacked, he met a warrior named Yami. He took him under his "care" and enlisted him to partake in the Black Bulls Division. There, he met some new friends and even took an interest in a boy who couldn't use magic but had a grimoire. His name was Asta, and he dreamed of becoming the Wizard King; a dream that Mark was surprised to hear about. But of course, to get there, he has to undergo serious training and defeat high-level threats to prove himself worthy of the title. After a long battle with a high-level threat, almost half of the Black Bulls disappeared leaving a black substance that almost looked similar to blood. What could it be? Where are they?
