After a run-in with a mysterious creature at sea, Hajime and his party’s search to find Myu continues in the ruins of an ancient city. Myu is miraculously saved by Meiru Melusine just before monsters pour into the city. Hajime’s party must team up with the Liberators, here from the past and armed with the magic of the gods. Together, they must defeat the horde in the second OVA of this story.
Hajime returns from the Sunken Ruins of Melusine. Feeling melancholic about having to part with Myu, he decides to take her on one last adventure. The voyage turns out to be more adventure than they had bargained for when a mysterious vortex approaches them while crossing the sea. Separated and surrounded by dark forces, Hajime must fight to find Myu in the first of two OVAs on this adventure.
While bathing with Myu Hajime overhears the ladies in the women’s baths demanding the story of how Kaori met Hajime. She reveals it was when she saw him defending a grandmother and grandson from thugs, despite still being weak at the time, and she fell in love with his humility and not his strength.
