Additionally, the masked man from the Noppera-Bo arc is voiced by Hikaru Midorikawa, and the fish demon from the Umi-Bozu arc is voiced by Norio Wakamoto.
Genkei, the monk from the Umi-Bozu arc is voiced by Frieza (also Mayuri from Bleach), which is hilarious, since Norio Wakamoto also did the voice for Cell (Dragon Ball). And Sogen, Genkei's disciple, is a certain emotionless Espada who happens to love pasta.
The worst part? It's Isane (also from Bleach) giving birth to a fish-baby thing... Yes, that means Kayo. Made even worse by the fact that Isane has an irrational fear of fishcakes. Worst fear indeed.
The Going Merry/Soifon/Cirucci Thunderwitch/MEDUSA is being abused by her husband in the Noppera-Bo arc.
Umi-Bozu Arc: Gilgamesh's (FateStayNight)/Rob Lucci's (OnePiece) worst fear is manju, apparently.
