Summer of...WHAT?

Konohagakure, the Village Hidden in the Leaves, home to the Hero of Leaf, Naruto Uzumaki-namikaze, former host to the Kyuubi no Kitsune, the Nine-Tailed Fox...

Three long years had passed since a young blonde shinobi, with an infectious smile, a ramen addiction, and a HIGHLY inappropriate Jutsu, named Naruto, had left the Village Hidden in the Leaves, the Third Hokage, Sarutobi Hiruzen, and his adopted daughter Tsunade Senju, who had been sent at age 7, to stay in Sunagakure, the Village hidden in the Sands, where she had lived for 11 years, until she had returned, 19 years old, bringing Shizune Katō, the sister of Dan Katō, her first love, who had been killed on his first B-ranked solo mission...she had been an unkind, uncaring girl, unwilling to even talk to anyone apart from her adoptive father and Shizune-Nee-Chan, until she was introduced to a blond-haired ball of energy named Naruto, aged 16, who had looked at her, then performed the Transformation Jutsu, copied her form perfectly, and sat in front of her, copying every single thing she did, until she looked up at him...and smiled. That was the first smile she'd made since Dan's death, and it was the start of Tsunade's spiritual healing...

THREE YEARS LATER...

22-year-old Tsunade Senju was rushing down the Main Street of Konoha, closely followed by her best friend Shizune Katō, in her pyjamas, bare footed, cropped silver-blond hair flying out behind her, unbrushed, causing Shizune to sigh mentally. 'Tsu-chan is going to complain about this later,' she thought ruefully to herself. 'She HATES having it brushed, and when it gets tangled...' she shuddered fearfully, as she had received frequent doses of Tsunade's Killing Intent, whenever something went wrong, which happened more often than she'd like. But today, brushed hair and proper clothes were the last things on Tsunade's mind at to moment. All she could think about was the fact that a young boy she had cared deeply for since the day they'd met. 'NARUTO'S COMING HOME!' She thought, grinning from ear to ear, her eyes flashing sea-green with pleasure. She was looking forward to his arrival so much, that Sarutobi had eventually thrown her out of the Hokage's Tower after she broke his third-favourite pipe by knocking it off his table and treading on she reached the Leaf Gate, she noticed domething that shook her out of her daydreaming. There was a large crowd, at least 20 people, mostly high-ranking shinobi, clustered around an object lying in the middle of the path, less than 2 metres from the gate. Tsunade caught a glimpse of the face and chest of the fallen starnger, who wasn't as strange at second glance after all...Blonde hair, wild and uncut, long enough to cover his back, three familiar marks on the one cheek she could see, scars? or maybe...whiskers? "NAAAARRUUUUTTTTOOOOOOO!"...
