He negotiates with the king and receives a plot of land—an empty, deserted plot of land, with no inhabitants in sight.

Hereby begins the Norio's colorful story—having a mermaid he fishes declare herself his wife, becoming neighbors with the Undead King, this is his busy but enjoyable life—and now a dragon appears?!
