The spelling of the word "kyoya" is influenced by the Japanese language, which uses a different writing system than English. In Japanese, the word is spelled as "きょうや" and pronounced as /kjoːja/. The first character "きょ" represents the sound "kyo," which is equivalent to "kiyo" in English. The second character "う" acts as a pronunciation modifier, elongating the sound of the previous character. The last character "や" represents the sound "ya," which is similar to the English word "yeah." Thus, the English spelling of "kyoya" reflects these Japanese pronunciations.
