It all begins with the main character Shurato Hidaka and his childhood friend Gai Kuroki competing in a junior tournament of martial arts. After winning several bouts, the two find themselves competing against one another in the finals. In the middle their bout a huge beam of light crashes down upon them from the heavens. Shurato and Gai are transports to a plane of existence known as Tenkûkai, the heavenly sphere and world of the Deva and Asura warriors.

Shurato and Gai are reincarnated Deva warriors. Vishnu, the Goddess of Harmony, summoned the two young men to aid her in a battle against the Asura clan who have plotted to destroy Tenkûkai. It was their destiny to return to Tenkûkai and protect the people and maintain peace and harmony.

Upon their arrival to Tenkûkai, Shurato and Gai were separated. A young girl named Lakshu finds Shurato lying in a open field. He is woken by a kiss and begins to ask her a list of questions. A small golden figure of a lion strapped to his belt catches Lakshu‘s attention. She asked if he is a member of the Hachibushu Deva clan, but Shurato doesn‘t have any idea what she‘s talking about.

Moments later, Gai appears on a hilltop fully armored. Happy to see his best friend, Shurato runs to meet up with him. Without hesitation Gai attacks Shurato in a malicious attempt to kill him. Confused and worried about his friend, Shurato struggles to fight against Gai. Later Shurato and Lakshu are saved by Reiga, the Phoenix warrior and taken to Tenkûden (Vishnu’s palace) to see Vishnu. There Shurato discovers that he and Gai are members of the Deva clan, also known as the Hachibushu (eight warriors). The golden lion he carries is referred to as his Shakti (armor).

Warriors of the Deva Clan

Later, General Indrah of the Deva clan betrays Vishnu and casts a spell to turn her into stone. Hyûga, the most loyal and dedicated Deva warrior, senses a problem from within Vishnu’s throne room and rushes to investigate. Hyûga finds the Goddess of Harmony covered in stone and also finds Indrah at the scene. Hyûga asks what has happened but no answer was given. The General attacks Hyûga to prevent him from discovering the truth.

Meanwhile, Gai approaches Shurato and attempts to kill him once more. Shurato tries valiantly to stop Gai from fighting, but Gai cares nothing for him. His intension is clearly set on killing Shurato. Focused on staying alive, Shurato finds himself in Vishnu’s throne room where Hyûga and Indrah are battling. Moments later Shurato and Hyûga are saved by Vishnu. The Goddess of Harmony sacrificed her remaining strength to teleport the two far from Tenkûden.

Back at Tenkûden, Indrah frames Shurato and Hyûga. The General tells the people of Tenkûkai that Shurato and Hyûga are responsible for Vishnu’s condition. To make matters worst Indrah announces that Gai will be taking command of the Deva clan. This deception turns the whole Deva clan against Shurato and Hyûga, and a man hunt for their heads began.

From there the story unfolds. Shurato and his group must revive Vishnu and save Tenkûkai before the Asura clan begin their invasion. - Jeff Anglea
