Volume Overview[edit | edit source]

After the events of the Dragon Wedding, Azusa's actions have garnered the attention of the Demon Kingdom.

Contrary to their menacing reputation, the demons wish to reward Azusa with a medal of honor for managing to broker a peace treaty between the Red and Blue dragons, which has brought a long-sought-after stability to the region.

With Beelzebub at the helm, the group sets out for the ceremony atop the majestic Leviathan, something reserved for only the most esteemed guests of the Demon Kingdom.

Unfortunately for them, Halkara's clumsy demeanor and oafishness causes a major political incident soon after they arrive, and Azusa is brought into direct conflict with the ruler of the Demon Kingdom, the Demon King, with the lives of her family and friends hanging in the balance.
