Will Sentai Jin avenge dead assistant and lose of greatest scientific data of all earthly time ? Raid no being space bug threat but look out for " Fire rocket five ! " Battel cry . A brief history of Jin . Steven Nawt Walking was once a world - famous quantum astrophysicist , known throughout the global scientific community for his work in intergalactic laser applications . Working on a groundbreaking study that promised to revolutionize intergalactic communication with extraterrestrials , Walking had already spent over 23 months collecting data when tragedy struck . In the early morning of June 21 , 1993 , Walking was making some final adjustments to his 152 cm laser telescope when a devastating meteor shower demolished the now - deactivated Altruista Observatory in Sydney , Australia . Walking was nearly killed ; he lost both legs and 73 % of his body was covered with third - degree burns . Walking ' s young assistant Angela , whom he secretly loved , was not so fortunate . She died of severe head trauma . She was only 23 . The freak meteor shower was no coincidence . After an in - depth , joint investigation by the INS , NASA , and the CIA , the destruction of the Altruista Observatory was linked to the menacing Team Space Bug . Apparently , Team Space Bug ' s Uchu Chu and Sky Deviler had been on an all - night Royal Jelly bender when they impetuously decided to set off gigantic ammonia - and - fertilizer bombs , aim their explosives at orbiting asteroids , and place bets on which earthly structures the falling fireballs would hit . Too hazy to remember what year it was , Deviler picked the Berlin Wall , forgetting that it had already crumbled . Too impatient to calculate vectors and trajectories , Uchu Chu chose the Altruista Observatory , simply thinking it ' d funny if two aliens wrecked a location dealing with distant galaxies . Uchu Chu won ; he later bragged about his winnings to an insect friend named Muffuru who , unbeknownst to Uchu Chu , was a spy for NASA . Despite the confession , charges against the two space bugs were dropped when Muffuru went missing . The poor , unsuspecting loser in Team Space Bug ' s gamble was Steven Nawt Walking . After receiving two mechanical legs and countless skin grafts , Walking was released from the Sydney Adventist Hospital and flown to a mountain sanatorium in Nagano , Japan , where he spent 19 painful months in rehabilitation . One morning , while Walking was lumbering along one of his prescribed mountain hikes , he met the revered Jujitsu Grandmaster , Yassu Yamataka . This fateful encounter would forever change Walking ' s life : Mr . Yamataka helped the recuperating genius learn the art of Jujitsu , transforming his mind and soul into that of a benevolent fighter of evil . Under the guidance of Mr . Yamataka , Walking was able to recreate himself into Sentai Jin ; an electro - mechanical fighting man - machine that is equal parts Jujitsu disciple , scientist , and armored tank .
