What if... the royal bloodline of the Demon Realm didn’t end with Meliodas and Zeldris?

Years have passed since the end of the Holy War and the fall of the Demon King. As Britannia slowly embraces peace, a buried truth begins to resurface. Deep within an ancient, forgotten library, Zeldris uncovers a fragment of erased history — a mention of a third prince, lost to time.

Shaken, he brings the discovery to Meliodas. Together, the brothers embark on a perilous journey to unearth the secrets their clan sought to erase.
Who is this forgotten sibling? Why was he erased from memory?
And more importantly... is he still alive?

A new tale begins — one of blood, betrayal, and a legacy long buried in shadows.

Meliodas x Zeldris Searching for a Forgotten Brother

The silence in the depths of the forgotten prison was suffocating.

The air was thick with dust, lingering enchantments… and secrets buried for far too long.

Meliodas stepped slowly toward the rusted bars of the cell.

The strange, weary-eyed demon stared back without blinking.

"How do you know we're looking for something?" Meliodas asked, cautious.

The old demon—Kaelis—gave a faint smile and stepped closer, dragging his chains behind him like echoes of the past.

"Honestly… very few ever come down here. Aside from the Demon King himself. So when two powerful demons walk through a corridor that hasn't been touched in millennia… it reeks of secrets, doesn't it?"

Meliodas and Zeldris exchanged a silent glance.

Kaelis continued, his pale eyes studying them intently.

"And besides… the way you both look, I could tell. You're not searching for a place… but a person. Or perhaps… a truth."

Zeldris stepped forward, his voice firm.

"We were told a demon locked away here might hold answers. Answers tied to a mystery about the royal demon bloodline. Is that you?"

Kaelis chuckled softly, a coarse sound that echoed through the cell.

"It's been a long time since I was anything more than a memory trapped between these walls. I barely know what's left of the outside world. But a mystery about the royal family? Heh… Now that's interesting."

Meliodas crouched down, locking eyes with the old being.

"By any chance… have you ever heard of a demon named Zephyr?"

The moment the name was spoken, Kaelis's face froze.

As if an invisible blade had pierced his chest.

His breath hitched, and his eyes widened.

The silence returned, heavier than before.

"Wh… What did you say?" Kaelis repeated, his voice suddenly trembling.

"Does that name mean anything to you?"

The old demon stepped back, as if reliving a memory buried deep within.

"That name… I haven't heard it in… in so long."

He looked up at them again, this time with more intensity.

"My name is Meliodas. Captain of the Seven Deadly Sins… and King of the Kingdom of Liones."

"And I am Zeldris. New King of the Demon Realm."

"Then… it falls to you… to carry the weight of this truth."
