All of the figures use a common 'MMS' (Multi Moveable System) body designed by Masaki Asai [ja].

There are three iterations of MMS (1st, 2nd, and 3rd), with 3rd coming in two body types (Short and Tall) to allow for different proportions depending on the character.

Konami also released action figures for various other IPs such as Sky Girls, Otomedius, Beatmania, Gurren Lagann, and Quiz Magic Academy [ja] using MMS bodies that are compatible with the Busou Shinki line: These were branded under the MMS label, but not the Busou Shinki label.

Exclusively sold on the Konami Style Japan page, these are unpainted, featureless MMS Figures meant for use with EX sets or for customization.

[7] The Megami Device line uses the Japanese model kit industry standard of 3mm joints, meaning that they are by default incompatible with the original Busou Shinki line, but Kotobukiya has released joint adapters that allow one to establish compatibility between 3.0 and 3.3mm standards.

BLADE was later commissioned for similar but different designs for Megami Device, unrelated to the Busou Shinki brand, which were announced in 2023 and had kits released in 2024.

Battle Rondo was a free multiplayer online raising sim set in the fictional Busou Shinki universe.

Shinki personalities (influencing actions they take in battle and how they respond to feedback) and stats were affected by the initial setup, in which the player selected three "CSC" core crystals.

[20] Busou Shinki Battle Masters was developed by Konami for the PlayStation Portable released 15 July 2010.

[24][25] Both were conventional action games, with the player taking direct control of shinki (unlike Battle Rondo).

[27] Busou Shinki: Battle Communication was a social game developed by Mobage for feature phones that was launched on 31 October 2010.

[28] Busou Shinki: Armored Princess Battle Conductor is an arcade game with four-player online battle royale gameplay, in which players take control of teams of three shinki and compete to collect the greatest amount of gems in a match, that was developed by Konami and released on 24 December 2020.

[30][31][32][33] Busou Shinki R was initially teased with no title in December 2017 [1] before being officially announced as a smartphone game in February 2020.

An internet radio show hosted by Kana Asumi and Minori Chihara to promote and discuss the TV anime series, broadcast on Onsen.ag from 24 September 2012 to 1 October 2013.

Character song albums, video game soundtracks, and radio show recordings have been released on CD.

The OVA was originally released as DLC for the PSP video game Battle Masters Mk 2, viewable through an in-game menu.

The TV series was licensed for distribution in North America by Sentai Filmworks and began streaming on Anime Network in 2012.

After the discontinuing of the action figure line, key staff such as series/MMS creator Masaki Asai and former series producer Toriwo Toriyama went on to work on the Megami Device line of model kits for Kotobukiya, which has a similar premise and concept and is considered by many as a spiritual successor.

[56] Fumikane Shimada and Takayuki Yanase also worked on designs for the game,[53][57][58] and Alice Gear Aegis has also had collaboration model kit releases from Megami Device.

[59] Pyramid staff such as president Junichi Kashiwagi are frequently present at Megami Device-related events as well, such as Wonder Festival talk shows.

[citation needed] Asai reported in February 2020 that development on Busou Shinki R had recently restarted from scratch.

This, combined with how Konami was not keeping him up to date on developments, with him not learning about the Battle Conductor arcade game until seeing announcements on Twitter, resulted in him releasing a statement on his personal blog saying that he no longer considers himself to be part of the project, citing the aforementioned incidents and how he is being kept out of the loop.

No work had been done on any collaboration model kits aside from the Edelweiss, Arnval and Strarf, and so it is unclear if any other revival designs will be released.
