"Your Companions Belong to the Overpowered Now" ~The Twin True Ancestors' Perfect Repayment~

At the farthest edge of the world stands a Kingdom of Eternal Night, constructed from moonlight and mirrors. A blood moon hangs eternally in the sky, and layers of fractured mirror spaces reflect distorted yet magnificent cityscapes. It is a sanctuary for exiles and creatures of shadow, and more so, the domain ruled with absolute power by the Twin True Ancestors—Melain the Black and Lucan the White.

Five years ago, a witch hunt launched by a Holy War Alliance cornered the sisters in the "Nameless Ruins." Just as Holy Nails and Sacred Flames were about to consume them, a young adventurer named Baine stumbled upon them by chance. He was a man of mediocre talent, with no knowledge of magic, barely surviving on his knowledge of herbs and his own strength. Yet, he mistook these millennia-old True Ancestors for "ordinary victims in distress." He offered them everything he had—his precious potions, his cloak to ward off the cold, and even clumsily set traps to lead the pursuers away.

This pure, unrequited kindness, something they hadn't felt in a thousand years, grew wildly into a morbid obsession within Melain's frozen heart and Lucan's deceitful soul: to "repay the kindness."

Years later, when the sisters awoke from their slumber and established the Mirror-Moon Kingdom with their overwhelming power, they immediately began to search for their benefactor. However, the sight before them drove them into a fury: their supreme benefactor, Baine, was still a low-rank adventurer struggling at the poverty line, fighting inferior monsters for a few copper coins

In the twisted logic of the True Ancestor sisters, Baine needed a "home" befitting his status, and loyal "attendants." Thus, they set their sights on your two companions—the pure-blood succubus, Anthea, and the genius witch, Mathea. This was not only to "repay" Baine for saving their lives, but also to eliminate the "inferior beings unworthy to walk beside him." They plan to abduct Anthea and Mathea, erase their wills, and turn them into the most perfect playthings and slaves to be offered to Baine, thereby imprisoning their gentle benefactor within the Mirror-Moon Kingdom forever, to become their exclusive, eternally trapp
