Kenta Date, a high-school student, is the ultimate champion of an arcade video game called "Megaranger". He belongs to the Cybernetics club, a group of like-minded friends from his school. Koichiro Endo, Shun Namiki, Chiasato Jogaseski, and Miku Imamura are also members of Cybernetics. The International Network of Excel-Science and Technology (INET), the game's creators, invite Kenta and the Cybernetics club members to tour the INET laboratories. Following a short tour of the INET HQ buildings, the company is attacked by the Neijirejia, an evil force led by Dr. Hinelar on a mission to conquer the current reality. Dr. Kubota, INET's chief scientist, reveals that Megaranger was more than only a simple video game but actually a combat simulator to identify potential recruits for a super fighting team to combat the Neijirejia. While the INET headquarters (HQ) is destroyed by the Neijirejia warrior Yugande, Dr. Kubota gives Kenta and his friends devices known as 'Digitizers'. By entering the key code "3-3-5" and shouting "Install, Megaranger!", Date, Endo, Namiki, Jogasaki and Imamura transform into the Megarangers to fight the Nejirejia. (Source: Wikipedia)
