Trivia: Saya no Uta

- Hikaru Midorikawa plays Lancer, Yuusuke Yoshino, Kyosuke Natsume, Tamahome, Heero Yuy, Dune, and Hayate.

- Yasunori Matsumoto plays Gourry Gabriev, Etemon, Mercurymon, Juna and Westar.
- Mitsuki Saiga plays Heinkle Wolfe, the female Zabimaru, Mina Hazuki.
- Playing Against Type: Mitsuki Saiga can pitch her voice down so much that her male roles sound like real males, not like someone with a female actress. Even her female roles have really deep, unfeminine voices. However, Ryōko is one of her few roles with a feminine, (not-so-)high voice.

- What Could Have Been: Nitro+ CEO Digitarou once expressed an interest of adapting Saya no Uta into a Hollywood Movie
