The first time Uchiha Aren died, he was a 32-year-old office worker hit by a truck. The second time he became aware of existence, infant eyes fluttered open to the sight of a red-and-white fan emblem - the Uchiha crest.
'I'm in Naruto's world... as an Uchiha!'
His tiny hands trembled with excitement. In his past life, he'd been an obsessive Naruto fan who could recite every jutsu, every clan secret. 'With this knowledge... I'll become stronger than Madara! I'll obtain the Rinnegan! The system cheated me into this world with all its advantages!'

Age 6 - Academy Entrance
Aren stood at the training grounds hours before dawn, kunai in hand. His father - Uchiha Taiga, a battle-scarred jounin - found him collapsed from exhaustion by sunrise.
"You're too young for this training," Taiga sighed, carrying his son home.
'He doesn't understand,' Aren thought, watching his father's three-tomoe Sharingan glint in the morning light. 'I have to work twice as hard to awaken my Sharingan earlier than anyone.'
That afternoon, he snuck into the Naka Shrine, tracing his fingers over the stone tablet only his Sharingan could properly read. 'If I can just decipher more...'

Age 9 - First Blood
The Third Great War raged when bandits attacked their supply caravan. Aren watched his cousin Takeshi take a spear through the chest - and felt his eyes burn.
'Yes! This is it!'
But when the heat faded, only a single tomoe spun in each eye. Not the immediate two-tomoe awakening he'd expected.
"You did well," his father said after the battle, not noticing Aren's disappointment. The praise tasted like ashes.
That night, Aren carved a new training regimen into his bedroom wall:
1. Master Fire Style by 10
2. Three-tomoe by 11
3. Develop original lightning jutsu
'I'll show them what a reincarnator can really do.'

Age 13 - The War's Cruelty
Bodies of Iwa ninja littered the battlefield, their blood mixing with rain. Aren's three-tomoe Sharingan panned across the slaughter - his doing.
'Why won't it evolve?' He clutched at his face, nails drawing blood. 'I've seen countless deaths! Felt rage! Where's my Mangekyou?!'
Nearby, 11-year-old Fugaku - his second cousin - screamed as his best friend died in his arms. The air shimmered with dark chakra as Fugaku's eyes morphed into an intricate new pattern.
Aren's stomach dropped. 'Him? Before me?'

Age 17 - The Breaking Point
Aren knelt in the Uchiha archives, surrounded by stolen scrolls. Blood dripped from his overused Sharingan.
'Failed again.'
He'd tried every Mangekyou awakening method:
- Killing his closest comrade (stopped at the last moment)
- Watching every squadmate die (they kept surviving)
- Even attempting Izanagi without proper eyes (nearly blinding himself)
The door creaked open. "Still at it?" Taiga leaned against the doorway, his own three-tomoe eyes weary. "Some paths aren't meant for us, son."
Aren smashed his fist into the stone floor. 'I was supposed to be special!'

Age 20 - The Resignation
Spring blossoms fell as Aren walked through Konoha's cemetery - not for the dead, but to escape his clan's disappointed whispers.
'Uchiha Aren - the "genius" who peaked at three-tomoe.'
'Even that Hyuga girl surpassed him.'
'Pathetic for a main branch member.'
"Oi! Aren!"
He turned to see Uchiha Yumi - a distant cousin with barely one tomoe - waving from her vegetable stall. "You forgot your groceries again!"
As she scolded him, sunlight caught in her ordinary black hair. For the first time in years, Aren didn't think about power.
---
Age 22 - The Wedding
Sake cups clinked under paper lanterns. Fugaku, now clan heir, gave the traditional toast. Across the room, Danzo's single visible eye watched Aren with clinical interest.
Yumi squeezed his hand. "You're thinking too hard again."
Aren studied their joined hands - his bore callouses from endless training, hers bore soil from her garden. 'This is enough.'
That night, as he placed the clan elder's haori over his shoulders, the last embers of his ambition finally died. The reincarnator who would shake the world became just another Uchiha.

The moon shone over Konoha as Aren stood on his porch, unaware that his greatest legacy wouldn't be his own power... but the extraordinary children he would one day father.
