- Casting Gag: Invoked — In the web DVD commentary of episode 1, it was confirmed that Crunchyroll requested Bang Zoom record the dub because of their experience with ONE's other manga adaptation. The ADR director and one of the writers for OPM were brought on board for MP100, and Max Mittelman (Saitama) and Erik Kimerer (Sonic) ended up voicing Ritsu and Teru.
- Executive Meddling: Just like what happened with the Latin American Spanish dubs of Miss Kobayashi's Dragon Maid and Free!, the decision of using Japanese honorifics there was forced unto the voice actors' throats by Crunchyroll, due to internal policies of the company, according to the people who worked on the dub.
