Mitsuki Ayano in Makeine: Too Many Losing Heroines! is voiced by Chiaki Kobayashi in Japanese and Conner Allison in the English dub.
Chiaki Kobayashi as Mitsuki Ayano
The anime’s official character page identifies Mitsuki (綾野光希) and credits Chiaki Kobayashi (小林千晃) as his Japanese voice actor. It describes Mitsuki as Kazuhiko’s classmate since middle school, Lemon’s childhood friend, and a book-loving student in his cram school’s advanced class.
Conner Allison as Mitsuki Ayano
Crunchyroll’s English-dub cast announcement credits Conner Allison as Mitsuki. That announcement is the direct source for the English casting used here.
