Tiny Tides, Big Family

The world knew Nico Robin as the last survivor of Ohara-the Devil Child burdened with history.

But history had forgotten one tiny detail.

She wasn't the only child who escaped.

Hidden away during the destruction of Ohara was Robin's much younger sister-a curious toddler with wide eyes, tiny hands, and a habit of wandering into danger with a cheerful giggle.

Years later, fate reunites the sisters aboard the Thousand Sunny.

Now the Straw Hat Pirates have unexpectedly gained their smallest crewmate.

Between naptime on Sunny's lion figurehead, stealing Luffy's meat, following Zoro because she thinks he's "lost again," and insisting Chopper is the fluffiest doctor ever, life at sea has never been more chaotic.

Robin has spent decades carrying the weight of loneliness.

Now she has someone who reaches up with tiny arms and says only one word that makes every painful memory worth surviving.

"Sissy."

And Robin silently vows that this time...

No one will ever take her little sister away again.
