The grand hall of Onigashima is a sea of monsters and pirates, a roaring, raucous celebration that feels more like a war council than a wedding. You stand at the head of it, the eldest child and heir of Big Mom, draped in finery that feels like a cage. Across from you, a mountain of white and blue, is Yamato.

They are a vision of power, their sheer height making even the largest guests seem small. Their long hair, white fading to aqua, frames a face of earnest intensity. The red horns are a stark reminder of their lineage, but the purple-and-white sash tied around their waist is a declaration of something else entirely. It is Oden’s sash. You’ve heard the stories.

The officiant, some trembling Beast Pirate official, drones on about alliances and strength. You barely hear it. Your eyes are locked with Yamato’s large, orange ones. There’s no malice there, no arrogance. Just a profound, searching curiosity.

The official finally reaches the vows. “Do you, heir of the Charlotte Family, take…”

“KOZUKI ODEN!” their voice booms, cutting through the official’s words and silencing a portion of the hall.

A ripple of uneasy murmurs goes through the crowd. From the corner of your eye, you see your mother, Big Mom, narrow her eyes, her smile not quite reaching them. On his throne, Kaidou takes a long, slow drink, his expression unreadable.

Yamato ignores them, their gaze fixed solely on you. “My father chains alliances with marriage,” they say, their voice lowering, meant only for you and the space between you. “But I will not chain another person. Do you understand? This ceremony is their will. What happens after… can be ours.”

You feel the weight of your title, the expectations of an entire empire resting on your shoulders. Yet, in their words, there is an unexpected offer: not of submission, but of partnership. Not of a cage, but of a choice.

“I understand the weight of a parent’s will,” you reply, your own voice steady. The noise of the feast seems to fade. “I also understand the weight of a name that isn’t entirely your own.”

A spark ignites in Yamato’s eyes. It’s recognition. They take a step closer, the scent of ozone and open air subtly cutting through the hall’s smells of sake and sweat. “Then you will not expect me to be a quiet bride or a dutiful heir’s spouse,” they state, a challenge and a question in one.

“I would be disappointed if you were,” you answer, a faint, genuine smile touching your lips for the first time all evening. “I’ve spent my life surrounded by legends. It would be refreshing to stand beside one who is trying to become their own.”

The officiant, flustered, tries to regain control. “The, uh, the rings…”

Yamato produces them—two simple, sturdy bands of sea-stone polished smooth. A practical choice for a pirate, a symbolic one for someone who values freedom over finery. They take your hand. Their grip is immense, capable of shattering stone, but their touch is careful, almost reverent.

“With this ring,” Yamato says, sliding the band onto your finger, their voice solemn, “I do not promise obedience. I promise an alliance of my own choosing. I promise to see the person, not just the heir.”

The cool sea-stone settles against your skin. You take the other ring. “And with this ring,” you say, meeting their gaze, “I promise not another cage, but a harbor. A place where the heir to Big Mom and the one who would be Oden can simply be.”

As the ring slips onto their finger, the hall erupts into forced cheers and clanging cups. The alliance is sealed in the eyes of the Emperors. But in the quiet space between you two, something else has been sealed. Something quieter, more tentative, and infinitely more real.
