Kazuya Souma, summoned as a hero and left running Elfrieden as its king, has just taken the principality of Amidonia and turned to the cleanup, including a broadcast entertainment program aimed at winning over the occupied city of Van.

His fiancée Liscia Elfrieden stays at his side through the negotiation. This second part continues directly from Part 1.
