The Kirameijin (Japanese 魔進合体キラメイジン; Bandai's official English romanization "Kiramaizin") is the main mecha of Mashin Sentai Kiramager, the 44th Super Sentai series (Japan, 2020–2021). Kiramager was never adapted into a Power Rangers season, so it is Japan-exclusive and has no official US name. It is formed from the team's five "Mashin," sentient robot partners with their own voices that are carried in gemstone form as "Kiramei Stones." The five core Mashin are Mashin Fire (fire engine, Kiramai Red), Mashin Shovellow (excavator vehicle, Kiramai Yellow), Mashin Mach (race car, Kiramai Green), Mashin Jetta (jet aircraft, Kiramai Blue) and Mashin Helico (helicopter, Kiramai Pink). Mashin Fire forms the robot's torso and head.

Combination happens in two stages: Fire, Shovellow and Mach first merge into the ground-based interim form "Land Mage," while Jetta and Helico form the airborne "Sky Mage"; the two together complete Kirameijin, which can then use the signature attacks of all five Mashin — for example Fire's extending ladder arm or Shovellow's excavator arm. Add-on Mashin and the "Mashin Weapon" line allow the robot to be re-armed and reconfigured, and later series mecha (including King Express and the drill mecha Gigant Driller) extend the combination system.

The DX toy was released by Bandai Japan as the "Mashin Gattai DX Kiramaizin Set" (Robo Series 01) in March 2020 and includes all five Mashin, which build into Land Mage, Sky Mage and the full Kirameijin. As is typical of modern Sentai DX mecha, the set is predominantly plastic with no significant die-cast content; each Mashin can be posed in vehicle or stone form and freely recombined. Being a Japan-only release, there is no Hasbro version; individual Mashin and expansion/weapon sets (such as the Machine/Weapon Set) were sold separately.
