We Are! HIKAKIN & SEIKIN – One Piece anime theme song / “ONE PIECE MUUUSIC COVER ALBUM”

ONE PIECE is truly popular with people of all ages, from children to adults.

And for those of a certain generation, it’s nostalgic—the very first opening theme, “We Are!,” sung by Hiroshi Kitadani.

That song has been covered by the popular YouTuber brothers HIKAKIN and SEIKIN.

It’s included on the 2020 compilation album ONE PIECE MUUUSIC COVER ALBUM.

The upbeat lyrics really lift your spirits.

The album itself is something anyone can enjoy, so I highly recommend it!
