One night, Meera was kidnapped by , a slumlord who ran an organ harvesting racket. Arjun saw the news. For the first time in a decade, he felt something: protectiveness .

Meera was saved. The police declared the "Ninja Assassin" a myth. Vikrant knew the truth but chose to look away. On the rooftop of the police station, Meera asked Arjun, "Ab aap kya karoge?"

Arjun was trained with 50 other children. They were taught to kill a man with a paper sheet, to vanish into the shadows, and to bleed without blinking. But Arjun had one flaw: he refused to kill a child. For this defiance, Ozuru burned the rudraksha off Arjun’s chest with a hot iron, leaving a permanent scar. "You are not Arjun," Ozuru hissed. "You are Roron —the Silent Death."

Deep in the mountains of Nagano, Japan, there was a secret training school called "Oni no ie" (House of Demons). Among the orphans was a timid Indian-Japanese boy named . He had been abandoned at their door as an infant, found with a broken rudraksha (holy bead) around his neck.

Finally, he faced Kaito. Kaito had a kusarigama (sickle and chain). Arjun had a broken metal rod and his rudraksha scar glowing red from anger. In a final move, Arjun let the chain wrap around his own arm, pulled Kaito close, and whispered, "Yeh dard jaap hai, Kaito. Mere bachpan ka hisaab." (This pain is a prayer. The price of my childhood.)

Mumbai Police were terrified. ACP (a tough, honest cop) was assigned to catch him. But Vikrant’s daughter, Meera , a crime journalist, began to suspect that the "Ninja Assassin" was not a criminal but a savior.

He escaped Japan and vanished into the chaotic streets of .

Arjun turned on his own clan. Using his ninjato sword and a storm of shurikens , he fought 30 ninjas. He was fast—faster than the wind. But he was betrayed by his only friend, , who stabbed him in the back. Left for dead at the bottom of a frozen waterfall, Arjun survived.

Arjun, his face half in shadow, smiled for the first time.

He threw a smoke pellet. By the time the smoke cleared, he was gone—leaving only a single black shuriken and a fresh rudraksha bead for Meera.

Arjun infiltrated Mansoor’s fortress—a massive, blood-soaked laundry factory. But Mansoor had hired help: and five elite Oni no ie ninjas had tracked Arjun to Mumbai.
