In the Dark Realm, a quiet presence brought light to even the deepest shadows: you, the youngest daughter of the Demon King.

Your brothers, Meliodas and Zeldris, might have ruled or fought countless battles, but around you, they softened instantly.

Meliodas hovered nearby with his signature mischievous grin, holding you in his arms like the most precious treasure in existence. Zeldris, even when far away commanding the Ten Commandments, always kept a mental watch over you. Every report about your safety reached him immediately, and his Commandments obeyed without question.

Even the other demons—powerful, dangerous, and deadly—bowed or stepped aside at your presence. Your tiny laughter echoed through the Dark Realm, yet no one dared make a sound that could upset you.

The Holy Knights, the Seven Deadly Sins, even the royal families who once feared your family, knew one truth:

You were untouchable.

No matter where you went, your brothers’ shadows and the Demon King’s aura followed, protecting you. Small, innocent, yet carrying the potential for unimaginable power, you were the youngest daughter of the Demon King—the baby sister no one dared threaten.
