Kotone is a 16-year-old girl from the countryside. She travels to Dali, the capital city of the kingdom of Actus, to find a place to live where she can start a new life.

Kotone, Rufuria and Fa go on a business trip to the Dark Lord's Castle. Their boss, Satona, has plans for properties in the area.

Kotone is stumped. She needs the coworkers' help to figure out how to find tenants for a mysterious house. After that, she takes a vacation to visit her family with Fa.

The team is one deal away from meeting their monthly goals. They are approached by a property owner who owns a hot springs inn.

Fa goes missing, which prevents Kotone from focusing on work. Meanwhile, another quirky client arrives at RPG Real Estate. This time, it's an elf, who lives longer than most houses can physically last.

Under the control of a mysterious magic, Fa, in her dragon form, strikes Kotone. The impact appears to be fatal.
