Namie Amuro and one piece once tied up twice.
This is the opening theme song "Fight Together" broadcasted from 10th April 2011 to 25th September 2011, this is the first tie-up song.
It is a refreshing number that seems to be Namie Amuro. Matching with one piece is also wonderful.
After that, we have also decided on the main theme song of the special version "One Piece ~ Adventure of Nebruandia" broadcast on December 19, 2015.
The song at this time is "Black Make Up".
Also refreshing at up tempo!
It seems that this animation was an original story not in the cartoon version.
As you can see, Namie Amuro and One Piece have strong ties from the past.
You can call it a popular artist like a one piece piece.
