Ok so Jizo if not the strongest of the nine guardians was definitely was one of the top 3. His ability has so much potential that its almost unfair to everybody else. The MC can basically be whatever he wants, mage, warrior, craftsman. He might not start out as the strongest of those specialties, compared to other guardian inheritors who are focused in those specialties but his potential to grow might allow him to even surpass them. I can definitely see why its called the 7 guardians and not 9. Jizo was probably killed by the other guardians because of his insane growth. Or mainly for some other reason but I am sure his growth potential was part of the reason for his death.
