is a Japanese media mix franchise from Konami Digital Entertainment, first launched in Japan in 2006 with a line of action figures followed by a companion online game. The franchise encompasses various manga, anime, novels, video games, and more.

The online game was shut down in 2011, and the original toy line was discontinued in 2012.

A revival of the series was teased in December 2017 and later revealed to be centered around a smartphone game, but the game was still in development hell as of February 2020.

Action Figures and Model Kits Original Line and MMS The action figure line was launched in Japan in September 2006. Many were based on character designs by prolific Japanese artists.

A few of the figures have been released for distribution outside Japan.

Busou Shinki action figures are presented as 1:1 scale, drawing from a fictional world featuring action figure-sized androids. The various media all take place in this same setting, though in different time periods.

Busou Shinki are feminine androids with stylized body armor and/or mechanical parts (such as the mermaid-themed Ianeira having a mechanical fish tail), but do have considerable variation in aesthetic between models that reflects the artistic license given to the different designers. Due to the setting, joints and screws in the action figures are considered to be part of the designs, and are frequently depicted in art, video games, and other media, though they are sometimes omitted or less significantly depicted such as in the TV anime.

All of the figures use a common 'MMS' (Multi Moveable System) body designed by . MMS figures have multiple highly articulated joints, which give them a wide range of possible poses, including a special swinging leg joint that allows for near-180 degree vertical articulation on legs. Additionally, multiple body parts are interchangeable, allowing a wide variety of customization without tools. 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. Busou Shinki only uses MMS 1st and MMS 3rd Short/Tall: MMS 2nd was only used for action figures for other IPs such as Beatmania and Gurren Lagann.

The series uses a 3.3/4mm standard for parts (both body parts and equipment) that allow them to be connected to other parts. This ensures compatibility throughout the line, but deviates from the 3mm standard used by most other Japanese lines, meaning that they are only compatible with each other.

Busou Shinki product packages come in several varieties such as full sets, EX sets, Light Armor sets, and bodies. Full sets come with a unique painted MMS body with head and a full set of equipment. EX sets only include a head and a small assortment of equipment, with no MMS body. Light Armor sets are complete sets of unique MMS with head and equipment but with a significantly smaller amount of equipment and accessories and a smaller stand compared to regular sets. Bodies are sold in blister packages that only contain an MMS body with no equipment. The Arnval Mk 2 and Strarf Mk 2 also had Full Arms Package releases, which had more weapons and equipment in addition to the original full set releases.

There were also multiple exclusive repaint versions only available from Dengeki Hobby, Konami Style, or events.

Konami also released action figures for various other IPs such as Sky Girls, Otomedius, Beatmania, Gurren Lagann, and using MMS bodies that are compatible with the Busou Shinki line: These were branded under the MMS label, but not the Busou Shinki label. A Hayate no Gotoku collaboration figure that came with a limited-edition version of the Hayate no Gotoku game Nightmare Paradise, however, was under the Busou Shinki label as it included Busou Shinki equipment (repaints of the Valona equipment).
