Otsutsuki Bloodline

At night, Uchiha Ao lay quietly on his bed. Because the Otsutsuki Bloodline he had just received had not yet fully integrated, he soon drifted off to sleep.

Not long after he fell asleep, a faint "click" sound came from his bedroom door. It was so soft that it did not disturb him.

The door was pushed open slowly, and moonlight spilled through the window onto the floor, outlining the figure of a person.

Her footsteps were light, making not the slightest sound.

The figure walked to the bedside, and without a moment's hesitation, she carefully lifted the quilt and slipped into the bed with light, practiced movements.

Her cold body was instantly enveloped by the warmth radiating from her younger brother.

She pressed her cheek against the top of Ao's soft hair and took a deep breath, the familiar scent lingering in her nose.

It's still most comfortable sleeping next to my little brother.

Izumi sighed softly in her heart, a satisfied smile appearing on her face involuntarily.

It was unknown how much time had passed, but the room was so quiet that only the soft breathing of the two could be heard.

Uchiha Izumi's eyelids grew heavier and heavier until she finally drifted into a sweet dream.

In her sleep, the corners of Uchiha Izumi's mouth curled up slightly, her face glowing with a happy smile as she began to mumble in her dreams: "Little brother... Big sister will always protect you... We won't be separated..." Her voice was soft and sweet.

Uchiha Ao seemed to sense something in his sleep; his brows furrowed slightly, and his arm subconsciously pulled Izumi closer.

As the morning sun climbed onto the windowsill, a thunderous roar suddenly shattered the room's tranquility.

"U-CHI-HA I-ZU-MI!"

Uchiha Izumi was jolted awake by the shout. Through her sleepy eyes, she saw her mother standing at the door, face full of rage, eyes wide as copper bells.

Oh no! I slept too soundly! Uchiha Izumi thought to herself, feeling a sense of impending doom. In her panic, she cast a reproachful glance at her brother beside her. "Hmph, it's all your fault!"

She scrambled out of bed, hurriedly tidying her messy hair and pajamas.

Uchiha Ao was also startled awake by the roar. He opened his eyes groggily, and seeing his sister's disheveled state, he instantly understood what was happening.

He sighed helplessly in his heart: Sister Izumi, how many times has this been? If you had just gotten up earlier, you wouldn't have been caught by Auntie.

Uchiha Ao was just about to explain for her, but before he could speak, Izumi's Mother had already stepped into the room, brandishing the duster she usually used for cleaning.

Uchiha Izumi, familiar with the routine, grabbed a set of outdoor clothes from the nearby rack and, seizing the right moment, jumped out of the second-story window.

She often slept in her brother's room, so she had anticipated this situation and kept plenty of her clothes there.

Izumi's Mother rushed to the window and shouted down at the street: "You get back here! Just wait until I get my hands on you!"

But Izumi's figure had already vanished around the corner of the alley.

Izumi's Mother went downstairs to chase after her, but not before reminding Uchiha Ao to come down for breakfast.

Just as Uchiha Ao was preparing to head downstairs, he heard Izumi's crisp, lively voice from outside the window: "Little brother, remember to leave the window open for me tonight."

He nodded, feeling somewhat speechless.

[Name: Uchiha Ao]
[Age: Nine]
[Bloodline: Otsutsuki Bloodline (Development: 2%)]
[Total Chakra: 5 Kakashi-units]
[Chakra Attributes: Wind, Fire, Water, Earth, Lightning, Yin, Yang]
[Skills: Fire Style: Lighter Jutsu...]
[Items: None]

After confirming that his sister had left, he sat at his desk and opened the system panel.

"Tsk. All these years of hard work don't even compare to a beginner's gift pack." Uchiha Ao clicked his tongue as he looked at the chakra attributes and total volume on the system panel.

"Naruto really is a world where bloodline reigns supreme. A blank Otsutsuki Bloodline alone gave me the power of five Kakashi-units and all chakra attributes," Uchiha Ao remarked in a low voice.

Although he always found the system's use of Kakashi as a unit of measurement ridiculous, five units was a massive improvement for him.

He then began to ponder a question.

How could he quickly increase the development of the Otsutsuki Bloodline?

"My mediocre Uchiha bloodline was able to increase the Otsutsuki Bloodline's development by two percent," Ao mused, resting his chin on his hand, his brows knitting together. "If I were to fuse with a stronger, purer bloodline, would the development rate skyrocket?"

The images of Shisui, Itachi, Sasuke, and Izumi flashed through his mind.

In the original story, Sister Izumi was actually an overlooked character.

In this era, for an ordinary Uchiha, being able to awaken the Three-Tomoe Sharingan was already considered a genius within the clan.

But those people were generally veterans of war and not particularly young.

Yet, Sister Izumi had awakened the Three-Tomoe Sharingan simply by experiencing the day of the clan's massacre.

And she was only thirteen at the time.

Wait? If I were to die in front of Sister Izumi, would she awaken the Mangekyo?

Uchiha Obito was able to skip the Three-Tomoe and awaken the Mangekyo directly; there was no reason why the more talented Sister Izumi couldn't do the same.

Uchiha Ao's thoughts wandered off instantly; of course, he didn't actually want to die in front of Izumi.

"It shouldn't be a problem to get some of Izumi's blood when she comes back tonight," Uchiha Ao said, rubbing his chin.

Konoha Village.

Uchiha Ao was dressed in a simple, plain-colored short-sleeved shirt. The fabric was soft and ordinary, devoid of any patterns that might reveal his status—most notably, the conspicuous Uchiha clan crest was nowhere to be found on his clothing.

The villagers of Konoha already harbored deep malice toward the Uchiha clan; why would he make himself so obvious? That would just be asking for unnecessary trouble.

Uchiha Ao walked slowly with his hands in his pockets, looking bored.

A soft, sweet voice drifted from behind him.

"Ao-kun..."

Uchiha Ao turned around and saw a petite girl standing there like a delicate sapling.

Her eyes were large and round, bearing the signature Byakugan of the Hyuga clan. Her pure irises lacked any visible pupils, resembling two pools of clear spring water; their clarity was tinged with an innate shyness and timidity that instantly stirred a desire to protect her.

"Oh, Hinata, long time no see," Uchiha Ao greeted with a smile.

Upon hearing Ao-kun's response, Hinata's cheeks turned bright red in an instant, the blush spreading all the way to her earlobes like a ripe red apple that looked as if it might drip blood at the slightest touch.

She lowered her head slightly, her hands nervously tugging at the hem of her clothes, her fingers twisting together to create wrinkles in the fabric.

After a long moment, she finally gathered the courage to speak in a voice as thin as a mosquito's hum: "Ao... Ao-kun, I... I saw you over there just now, and I wanted to... to come over and say hello."

Having said that, she quickly bowed her head again, not daring to look at Ao.

Uchiha Ao gazed at the Hinata before him, and a strange sensation suddenly welled up in his heart.

It was an inexplicable attraction, different from the simple fondness one might feel for a cute girl.

It felt more like an attraction between bloodlines.

Could it be because of my Otsutsuki Bloodline?
