To the Wives Who Were Heroes

Once, a terrifying demon lord named Nefarius spread fear across the land.
A band of adventurers led by the young Arthur fought a fierce battle and finally defeated him.
They became celebrated as heroes, and in the newfound peace of the world, each set out on their own path in life.
 
Ten years of tranquility passed. Then, Ryan, the fortune-teller who had joined the battle against the demon lord, foresaw the birth of a new demon lord.
To prevent the world from once again facing destruction, the women who were once hailed as heroes now reunite—though they have since become wives.
 
However, the new demon lord awaits its birth deep within a dangerous dungeon, and with their former strength long gone, they stand no chance…
Thus, Ryan the fortune-teller and the wives who were once heroes decide to unleash a forbidden art.
 
Its name: Berserkle—
 
A forbidden technique said to shine a light if wielded by the righteous, but to plunge one into lust if wielded by the wicked.
Will the future be one of pure love, or one of debauchery? The choice is yours—
“Whether it is pure love or lust, whichever path we choose… we can never be who we once were.”

The night before the final battle──
With his mission of defeating the Demon King fast approaching, the hero Allen is staying at his last inn.
“My chances of winning are 50%… If I lose, I’ll die, and remain a virgin.”
His companion, Mireille, is a busty half-elf dressed provocatively.
Allen gives Mireille a suggestive drug… and plots to do something naughty to her…!
