One Piece's Wano Country Saga introduced many new characters, but most will likely only be relevant for this one arc. Naturally, Kaido and his Beast Pirates were the main attraction for many fans. However, of the 20,000 pirates affiliated with the Emperor, only a fraction were given distinct roles during the arc. They include the King of the Beasts, the All-Stars, the Tobi-Roppo, and a handful of Shinuchi and Gifters. After dividing up Wano's new characters this many times over, fans are left with a few minor characters whose names might not be worth mentioning even within the context of this arc. This is how one can come across a Gifter like Sarahebi.
