Uchiha Shisui was known for many things. His genius genjutsu-skills, his rather convenient use of shunshin, his prowess with the tantō and his high pain tolerance. However that is all Shisui the Shinobi. Uchiha Shisui was, in fact, very different from what most would think.

4 years 4 months 2 days

At such a young age, Shisui would naturally not know the difference between different kinds of pain, so when his aunt suddenly started screaming from pain in the kitchen, he ran as fast as legs could carry him.

"Shisui, Shisui honey come over here and hold my hand will you?" his aunt grunted out, it wasn't her usual nice tone, it was bordering on an order. Shisui took her hand and immdiately regretted his decision. It felt like his aunt was trying to kill his hand.

"Aunt Mikoto! Wha-What's wrong?!" Shisui was panicking, he did not know what was going on and it all went by too fast for him to comprehend anything. He realized that they were the only ones in the compound because of the war going on, all the civilian clan-members were helping out with the orphanage or at the hospital.

After hours of agonizing pain and loud screams, it finally stopped. His aunt looked exhausted, and he was no better off himself, that woman most definetely broke all the bones in his hand.

Shisui crawled over to his aunt, who had picked something off of the couch. He didn't even know how he had gotten to the couch in the first place, but that didn't matter. He saw his aunt sit there with a little boy, coal black hair and matching eyes.

"Aunt Mikoto... Who is that?" Shisui asked carefully, he was quite certain that the little baby hadn't been there just a few minutes earlier.

"It's your cousin honey, his name is Itachi, now will you be a sweetheart and get me some hot water and a few towels so I can clean him a bit?" Shisui did as he was told and helped his aunt clean the boy.

"Shisui, Itachi seems to like you" he looked at his aunt, who was pointing at Itachi. The little boy was staring at him with a happy smile on his face, his small hands uncoordinated and his big eyes were staring right at Shisui. All in all, Shisui thought the boy was the cutest being he had ever seen. "Can I carry him aunt Mikoto?" Mikoto happily agreed and handed her newborn son over.

Shisui lost count of time while sitting with Itachi, the little boy seemed content holding Shisui's larger fingers, biting on them from time to time. He hadn't noticed that his parents and the Uchiha clan head were standing right behind him, looking at the scene with warmth in their eyes.

While Shisui was sitting there with his baby cousin, he made a promise to himself. He would do everything he could to make sure that Itachi had a painfree life.

A/N: Ok so the first chapter is shit, I know! But still, it's my first fanfic! And just so you know, I put alot of thought in Shisui's character. I don't want him to be all playboy or hyperactive or anything. He's gonna be a calm boy with a nice sense of humour *cough*closetpervert*cough*. Even his birthday is well thought out! Shi means death, but it can also mean four, Itachi's astrological sign is Gemini and Gemini is super compatible with Aquarius, so I made Shisui's birthday be on February 4th! He's also 4 years older than Itachi in this story, and I made him seem really dumb here, but he's already genin at 5, considering that it's war in the timeline that Shisui/Itachi were born. Anyways, hope you guys like it!:)
