Death Note Rule: The human whose name is written in this note shall die. The user must know the target's face and write their name while picturing it. Death occurs within 40 seconds unless a specific time and cause are stated.

Konoha buzzed with the fading echoes of the Second Great Ninja War, its streets a mix of weary shinobi and hopeful civilians rebuilding under the shadow of the Hokage Rock. In a modest home near the village's edge, a newborn's cry pierced the night of March 3, 20 years before Naruto Uzumaki's birth. The child, named Kira by his civilian parents, was no ordinary soul. As his mother cradled him, a vision flooded his reincarnated mind—a divine entity, radiant and formless, spoke with a voice like thunder over a silent sea.
"Kira," it said, "humanity strayed when Kaguya and the Sage of Six Paths gifted chakra, twisting their path from progress to war. You are my instrument to judge evil and restore balance. This Death Note is your tool—use it wisely."
The vision faded, leaving Kira's infant mind reeling. He couldn't grasp it fully, but the weight of his purpose settled like a stone. The Death Note, a black-bound book, appeared in his cradle, its pages blank to his parents' eyes, a mere notebook. To Kira, its power was clear: write a name, picture a face, specify a time and cause, and death would follow. Each kill would grant him the victim's lifespan and chakra, despite his lack of natural chakra—a divine boon to reshape the shinobi world.
Years passed, and Kira grew as a quiet, observant child in Konoha's civilian district. By age eight, his reincarnated memories sharpened, urging him to act. He studied the village from the shadows, noting its factions: Hiruzen Sarutobi's watchful governance, Danzo Shimura's secretive Root, the Uchiha's proud patrols, the Hyuga's piercing Byakugan, and ANBU's silent vigilance. A civilian with no chakra, Kira knew he must remain invisible, his Death Note hidden in a chakra-sealed box only he could open, its true nature disguised as a scholar's journal.
On a humid evening, June 10, Kira sat in his room, the Death Note open before him. He'd overheard whispers at the market: a merchant, Hiroshi Tanaka, was extorting war-weary families, hoarding supplies for profit. Evil, Kira thought, recalling the divine entity's charge. He tested the Death Note's power, his hand trembling as he wrote: "Hiroshi Tanaka, heart attack, June 10, 8:30 PM, collapses in his shop.
"Kira pictured Hiroshi's weathered face, seen that morning haggling ruthlessly. At 8:30 PM, a commotion erupted in the market. Rushing to the window, Kira saw a crowd around Hiroshi's shop. The merchant lay dead, clutching his chest, exactly as written. A surge coursed through Kira—not just satisfaction, but a faint pulse of chakra, Hiroshi's meager energy now his. His lifespan extended, a whisper of years added. The Death Note worked, its power undeniable in the Naruto world.
Guilt flickered. Hiroshi was evil, but a man with a family. Kira pushed it down, journaling his thoughts: Is this justice? The God chose me to judge. He resolved to refine his targets, focusing on those who fueled chakra's corruption—shinobi who thrived on war's chaos. But Konoha's factions loomed. If Hiruzen or Danzo suspected a civilian, he'd be hunted. The Uchiha's Sharingan or Hyuga's Byakugan could pierce his secrecy. He needed allies, a network to gather names and faces without exposing himself.
At the market the next day, Kira approached a young trader, Riku, who'd suffered under Hiroshi's schemes. "I heard he's gone," Kira said, feigning innocence. Riku's relief was palpable. "Someone did us a favor," he muttered. Kira smiled, planting the first seed of his network. Riku could provide rumors, names of corrupt figures. No one would suspect a boy with no chakra, a scholar's son scribbling in a plain notebook.
As night fell, Kira hid the Death Note in its sealed box, his mind racing. The divine entity's words echoed: Judge evil, restore balance. The shinobi world was vast—Akatsuki's shadow, Tailed Beasts, and figures like Kaguya awaited. He'd need more chakra, more lifespan, and absolute secrecy. The path was clear, but perilous. A single mistake could draw Danzo's Root or ANBU's blades. Kira, the Shinigami of the Shinobi World, began his silent crusade.
