Murai (村井 Murai) was a Rogue Ninja and a boss from Ninja Gaiden and its variants Ninja Gaiden Black, Ninja Gaiden Sigma and Ninja Gaiden Sigma Plus, where he appears as the central antagonist and final boss. He is the late uncle of Ryu Hayabusa, late brother-in-law of Jô Hayabusa and former Ninja Master/Warlord of the defunct Shadow Ninja Clan.
Murai has a tall and large muscular build with long white hair, the symbol of his own ninja clan tattooed on his left bicep and a scar under his right eye, showing him as an old but extremely fit man. His ninja outfit consist of a gi, tabi boots, armbands, a belt, knee pads, and a head band.
Murai is power hungry, ruthless and very manipulative. He is more than willing to kill his closest ally and nephew after they outlive their use, all for the pursuit of power. He views his Shadow foot soldiers as ashigaru-sha.
Originally a member of the Hayabusa Ninja Clan, Murai became a rogue ninja and left under unknown circumstances to start up his own ninja clan, declaring his rogue ninja clan: the Shadow clan. His main base of operations is the Ninja Fortress near the Hayabusa village, where he gathers intel through his network of ninja. The Shadow ninja clan is on neutral terms with the Hayabusa clan.
Ninja Gaiden Sigma
Residing within the Shadow clan's Ninja Fortress, Murai made a pact with the Vigoor Emperor and carefully orchestrated and set in motion his master plan to gain the power of a dark deity. His first act was to tip off the location of the Dark Dragon Blade to the Vigoor Emperor, knowing that they would send their general, the Greater Fiend Doku, and an army of Vigoorian Samurai to retrieve the Dark Dragon Blade. At the same time, Murai gets his young servant Ayane to lure his nephew, Ryu Hayabusa, away from the Hayabusa village for "special training" at the Ninja Fortress. In the Ninja Fortress, Ryu is ambushed by Murai's Shadow Ninjas. After defeating waves of Shadow Ninjas, Ryu finally faces Murai and they fight to a standstill. They then have a conversation, where Murai inquires about the Dragon Sword and Dark Dragon Blade, to which Ryu apprehensively answers.
While Ryu is away from his village, Doku attacks with his Samurai army, slaughtering the villagers and razing buildings in a hellish fire. Ayane arrives to inform Murai about the attack, prompting Ryu to quickly rush back to his village. Once there, Ryu butchers the samurai army over a series of many fierce battles, ultimately facing the Greater Fiend, where an exhausted Ryu is cut down by Doku wielding the Dark Dragon Blade.
Upon Ryu's resurrection by the Hayabusa Guardian spirit, Murai manipulates him further by directing Ryu's rage towards the Vigoorian Empire, motivating him into pursuing Doku, urging Ryu to slaughter all who stands in his way without mercy, for only the deaths of many would feed and call out the Dark Dragon Blade. As Ryu journeyed to Vigoor, Murai donned his Dark Disciple persona as well as sending Gamov and Ayane to watch Ryu's progress.
Under the guise of the Dark Disciple, Murai watches from behind the scenes as events unfold and realities start to shift and twist as the Emperor breaks the Dark Dragon Blade's seal and imbues himself with powers of all the Evil Deities. This cumulates in a final epic battle between Ryu and Vigoorian Emperior in his deity form. As Murai expected Ryu defeats the Emperor and barely escapes with the aid of Rachel, resulting in the Dark Dragon Blade falling right before a patiently waiting Dark Disciple. Revealing that he is indeed the Dark Disciple, Murai finally puts his master plan into full swing and grabs the Dark Dragon Blade for himself. With his new powers Murai quickly vaporizes his ally Gamov and transforms into the Devil Incarnate. With the power of the Dark Dragon, Murai fights a tough battle with his nephew, trying to kill him. However he underestimates Ryu's abilities and the strength of the True Dragon Sword, ultimately resulting in his downfall and defeat. Wounded by Ryu, the fiendish Murai drops the Dark Dragon Blade, and collapses, falling into a deep cavern.

- Windmill Shurikens: As the Devil Incarnate, Murai is able to summon a group of these large shurikens and telekinetically toss them at his enemy.
- When first encountered, Murai will be wielding the nunchuku. He proceeds towards you slowly, but will somersault at times to get to you quickly.
- Attacking head on is suicide, as his nunchuku attacks are quick and can deal a large amount of damage before you can counter back. Get too close and he'll perform a devastating grab.
- If you attempt to flee from him do not jump, as his nunchuks have a wide range of attack, instead somersault then jump back.
- The best recommended tactic to use would be to run up a surrounding wall and perform a drop attack when he is close. He is likely not to block it or evade and deals a moderate amount of damage.
- On Very Hard and Master Ninja difficulty, the best way to open him up is to keep a distance and bait him into doing a roll towards you, and then quickly do foward + XX with the Dragon Sword to damage him.
- In Ninja Gaiden Black and Sigma he is accompanied by Ninjas in higher difficulties.
- In his devil incarnate form and as the final boss of Ninja Gaiden Murai will be wielding the Dark Dragon Blade. His combos are devastating but easy to avoid. The best tactic would be to perform a mid air homing attack as it is quick an nimble.
- Watch out for his Dark Dragon Ninpo. Though it is easy to avoid, it inflicts severe damage or an instant death in higher difficulties.
- He is a fairly easy boss and can usually be defeated in one try given you have a moderate amount of elixirs, health or Talismans of Rebirth.
