Trivia

 * Jei is the Japanese pronunciation of the letter "J." This parallels Shī's name, which is the pronunciation of the letter "C," and Killer Bee's name, as "bī," the Japanese pronunciation of "Bee," is also the Japanese pronunciation of the letter "B." The Fourth Raikage, also pronounces his name as "A" in English translations and "E" in Japanese.
