One Piece: Black Jade Qilin, Taking Down Arlong from the Start

[Joining the crew] + [Multiple love interests] + [Transmigration into the body] + [Mythical Zoan: Black Jade Qilin] + [No System] + [Character growth]

The frail young Sinuo, who has lost his memories, is found by Nami on the beach and brought home.

Determined not to be a burden to his family, Sinuo trains as hard as he can, but sees no results.

That is, until the Arlong Pirates invade Cocoyasi Village...

Sinuo, sunk beneath the sea, shatters a mysterious shackle inside his body...

A human who can breathe freely underwater?

A Devil Fruit User who is completely unaffected by seawater? Who can even control the currents?

As the shackles inside him are unlocked one by one, more abilities gradually emerge.

Sand? Lightning? Flames? The Heavenly Eye? Iron Balloon?

And the secrets he carries begin to come to light...
