- The Other Darrin: In the English version, Kazami, one of Kyo's friends, was voiced by Jessica Dismuke in episode 7 and replaced by Luci Christian in episode 15.
- Shirley was voiced by Ashley Moynihan in the TV series but was replaced by Cherami Leigh in the Infinity OVA.
- Playing Against Type: In the dub, Monica Rial was intentionally cast against type as Jo. In the DVD Commentary, she mentions that she went in to audition for Amy and the director wouldn't let her. Alison Viktorin ended up voicing Amy.
- It is so bizarre to hear Monica's 'real' voice after watching several of the episodes - and yes, her natural voice would have been perfect for Amy. Pretty impressive bit of voice acting.
- Portmanteau Series Nickname: "Bakuten".
- What Could Have Been: As mentioned in the Playing Against Type example, Monica Rial was considered to voice Amy.
