Someday, it'd be Nice if We Could all Go to a Festival Together Again Episode 9

The Quest Dorm members, alongside Souta, Nanami and Hakua safely arrived at Bladefield. But their happiness was not for long, that Nanami and Hakua's father are said to be deceased recently. The first prince, Elia, then uncover the truth; he is the real father of Nanami and Hakua. A condolence ceremony is then done to mourn the deceased king, and celebrate Elia's coronation as the new king at the same time. Souta then met No. 0, the leader of the Council of Seven Virtues. She then explains about Bladefield's fairy tale, about a nameless person who has been changed into the flag, two princesses and ten heroes. Souta realized his destiny that awaits him at the end of the path. No. 0 asks Souta to help her to save the world with his power.
