Trivia / Frame Arms Girls

• Author Appeal:
  • Fumikane, being the main designer for several of the FA Girls, originally designed them with stoic/neutral expressions and modest bust sizes. In addition, his traditional Mecha Musume design style can be seen in their armor.
  • E-ji Komatsu, being the main designer for Hresvelgr, models her body suit after School Swimsuit, a staple of his design style.
• Author Avatar: Humida began using a Charger bristling with charging cable "tentacles" as his avatar on Twitter after the fans had a laugh at a screenshot from the show that superimposed his name in the in-line credits with a picture of Charger.
• Follow the Leader: Amusingly, a multi-stage and multi-layered example that spans decades:
  • Bandai started the mecha musume figure craze with their Gundam Girls sub-franchise in the 1980s with cute girls dressed up like mobile suits.
  • Konami then created a major niche in the market with their Busou Shinki in the 2000s, but stopped production in the 2010s due to their unsuccessful attempt to rebrand into a pure Pachinko company, leaving a gap in the market. Kotobukiya bought over a lot of the now-laid-off Shinki engineering team, and used their talents to make vast strides in improving the newly-created Frame Arms Girls. This allowed them to follow the lead on mecha musume and carve out their market share, which in turn allowed them to invest more in improved engineering for successive waves of FA Girls, further cementing their corner of the plamo market.
  • Bandai, seeing a plamo competitor suddenly carve out a significant market share in mecha musume kits, counter-escalated by making their MS Girls kits for Gundam Build Fighters and then Build Divers (to mixed reactions, with Sarah and Ayame being their most successful figures), in addition to designing and releasing more Armored Girls Project mecha musume action figures. Goodsmile and Max Factory followed suit by striking deals to create nendoroids and figma for the Kantai Collection and Azur Lane series of mecha musume.
  • Konami, now returning to the gaming industry in infamy and ignominy, strike a contract with Kotobukiya to assist in reviving their Busou Shinki with the Rebuild/Re-Arm/Revive series. The project then never materialized aside from the first kit in the line.
• Mutually Fictional: The movie makes it much less clear whether the "real" setting is the one where the FA Girls are tiny robots or the one where they're humans, setting its framing device in the latter.
• What Could Have Been: Several of Humida's prototype designs are slightly different from the final releases. For example, Architect's hair colour and style changed from green with twintails to a bluish-white Hime Cut. and Jinrai changed armor colours several times, resulting in her fuchsia and indigo colour variants.
