This is the story after the happy ending.

High school student Amakusa Yuuto, who was transported to the fantasy world Bluewards, became a Great Magician and saved the world with his companions.

Now, for the female Holy Knight Waldetrude, who was ennobled for her achievements, he finds himself involved in territory management.

However, problems abound: the reconstruction of a ruined city, a dwarven village that no longer produces iron, a maritime city refusing to pay taxes, and villages plagued by monsters.

Yuuto, now Bluewards' strongest adventurer, joins forces with his companions, tackling these challenges sometimes with magic, sometimes with modern knowledge, but mostly with overwhelming financial power!

Until the day, one year from now, when he returns to Earth.
