On the continent of Rainica, there have long been Heroes—chosen ones who protect humanity.
As chosen humans, the Heroes eliminated threats with their power and were praised as heroes, securing not only military but also political positions.
However
In contrast to such Heroes, a few beings appeared who brought threats to the world.
Each one possessed extremely powerful strength, and their very existence was a threat to all humans.
Humans called them Legion Commanders.
The Legion Commanders used their innate powers to start wars, and as they fought against the Heroes for a long time, their generations changed along with the Heroes.
And
The worst, most malevolent, and strongest Legion Commander to be recorded in history appeared.
Legion Commander Yomi
With the appearance of one who displayed overwhelming power and cruelty compared to previous generations or other Legion Commanders, numerous Heroes risked their lives to battle Yomi, barely weakening him and forcing him to retreat.
Eighty years passed, and a new Hero, Rian, appeared.
His personality and private life were certainly far from what a Hero's should be, but his power, authority, and appearance were superior to past Heroes, enough to offset all of that.
Rian recruited many party members, and among them, there was one who clearly stood out.
Seira, Rian's maid and one of his party members.
With her beautiful appearance, voluptuous physique, and strong power despite being a maid, she drew the attention of all men, and Rian was no exception.
