Suzukuri Dragon

The setting is Middle Ages Europe style.

A dragon male (the protagonist) must, in order to marry, amass a lot of treasures and wealth in his dungeon. For that reason, the protagonist went alone and lived in an area where human lives, constructed a huge nest and started amassing treasures. However, soon after the nest got built, gallant heroes wanting to exterminate dragons, townspeople that see the dragon as a nuisance and adventurers and thief out to get the dragon's treasure came.

With this, he couldn't gather treasures at ease. Therefore, the protagonist hired monsters, added traps and threatened the neighboring area to not approach his nest. With his nest's defense strengthened, the protagonist started amassing wealth. He searched for a gold mine all over the place, started farming, deforested the forest to build drawers out of it. Of course, the foolish invaders that's successfully repulsed are stripped of all their possessions. Incidentally the women are used as sparring partner to gain experience for the honeymoon.

Will he succeed in amassing treasures and marry his fiancée? Or would he meet some other woman...?

[Translated from Getchu]

Hire monsters, build traps to repel invaders all while you amass treasures by terrorizing the neighborhood!
