Hideaki, upon leaving the Uchiha Clan, lost both his surname and his clan's protection. To compensate for this problem, Hideaki took on his great grand-mother's maiden name, Endoh, and had been relying on Inoichi and his wife, Miharu, for groceries and supply shopping for both himself and the depressed Anko, doing odd jobs in return, saving them the trouble of having to hire a genin team.
The Seal Master eventually turned up and deemed the Maternity Seal non-aggressive, having long since reached its purpose and stopped progressing. Tests were done and it was found that he had grown thirty-two extra muscles, upped his strength to twice that of even the most physically fit person his age, regardless of build, tripled the speed and heightened his senses past those of any of the other clans. His condition was declared an S-Ranked secret of the Hidden Village of Leaf.
Three months later, Hideaki managed a glimpse of Itachi on his first day at the Ninja Academy. Hideaki's 'death' had obviously hit the second son hard, sending him into the same apathy as his brother, but driven by a deep-seated determination and ambition that Hideaki, himself, lacked.
He had also seen his very pregnant mother. Despite the healthy flush of pregnancy, Michiko looked miserable. He later heard that she gave birth to a boy she named Sasuke.
Fugaku looked much as he always did. The Prick.
Then, one day in October, the Kyuubi attacked.

It seemed to him that, while he had no qualms about whacking Hideaki around, the Kyuubi didn't land a single crippling or fatal blow to the boy. Several minutes into the battle, Hideaki finally noticed that the Seal on his back was pulsing.
One can only assume the Kyuubi didn't want to cause friction with Hideaki's demon surrogate mother, and that is probably why the giant fox kept giving him irritated looks. Hideaki was eventually knocked out when he was thrown into a tree.
The once Uchiha, now Undoh, woken ten or twenty minutes later. The Kyuubi had moved off towards Gamabunta, the Frog Boss. Hideaki could just make out the Yondaime standing on Gamabunta's head.
There was a bright flash of light and the Kyuubi vanished with an enraged yowl. Then Gamabunta vanished and the Yondaime free fell towards the ground.
Now don't get him wrong, Hideaki respected Arashi as the Hokage (mostly), but he didn't really like him as a person, yet still he found himself running and jumping to catch the falling man.
With a final leap, the young Jounin caught the falling blond not two metres from the ground. Even before he landed, Hideaki knew the man was dead.
There was a weak cry from the bundle the Yondaime held in a death grip. Hideaki had a sinking feeling in the pit of his stomach.
He laid the still form on the ground, arranged the limbs and closed those blue, blue eyes for the last time before turning his attention to the baby. It was…a new born blonde baby boy. A spiral seal burned red on his belly.
Hideaki became worried. If the Kyuubi was truly sealed in the child like he believed, then there would be countless assassination attempts on his life, both from without and from within. He, himself, had seen what people did to their own if they blamed or suspected them of a wrongdoing. This kid was effectively damned by the Yondaime the moment the seal was put in place.
"Yondaime-sama!"
Hideaki sat back on his heel and looked around, fully alert. Shinobi were coming.
The boy stood and began to move off; if he was here when they arrived, they might blame him for their hero's death. The baby whimpered and Hideaki paused, glancing back.
They would almost definitely kill the baby.
Sighing, Hideaki dashed back, snatched the baby up and took off. Maybe he could leave it in the rubble of the Konoha Hospital Nursery Wing.
This decision was promptly dashed when he recalled that he had been drafted into evacuating the brats. Leaving him in the rubble of a house was out of the question because questions would be asked if that family didn't have a baby. Taking him to an orphanage wasn't even considered, that would be the first place they would look if they did a search for the kid and he was a new born.
Thus it was, with great reluctance, that Hideaki took the kid home to Anko.

Four months later, Hideaki was cursing the moment he gave the kid to Anko. While Hideaki was busy stealing everything the kid would need while there was still anarchy from the demon fox's attack, forging the necessary documents and lying through his teeth to his superiors, Anko was quite happily playing mother with the baby she had started calling Tadashi, 'faithful servant'. His official name (the one on his forged birth certificate) was Undoh Toru, 'distant wisteria' and 'sea'.
Though, granted, arguing her into taking tablets to stimulate milk-production was rewarding. She was pretty mellow after that. She was also pretty upset that she couldn't take anti-depressants anymore because they might have affected the baby.
Speaking of babies, Yamanaka Miharu had recently given birth to a blonde baby girl. Ino. Hideaki had always thought babies were the same until they were three or so. This was proven to be false.
Ino was a screamer, true, but lethargic for the most part. She slept away twenty hours a day and demanded to be fed every four hours.
Toru, however, was generally a happy and easy to please baby, if entirely too active. He learnt to smile and giggle at three months, he demanded a drink every two to three hours a day and twice during the night. As such, he pooped and peed a lot. Miharu always commented on his pro-ess at changing a diaper or burping a baby.
Six months from the Kyuubi's attack, Anko was deemed stable enough to return to duty. This posed a problem since Hideaki was already doing extended missions and had been put forward for promotion into the Inferno Squad of the tracker-nins Black Ops. He didn't honestly think he would get it, but why take the chance? The problem was that with Anko on missions, there would be no one to look after Toru.
He had ended up going to Miharu and spilling the whole story. At first she had been frightened, but once he explained his reasons why, she agreed to look after the little boy. She was wary of Toru for several days until she got to know him.
Years passed and Hideaki did, surprisingly, get accepted into the Black Ops unit. His code name was Aki and he found the gruesome work surprisingly enjoyable once you were desensitised. Anko ended up becoming apprenticed to Morino Ibiki, the head of the Special Jounin Interrogations Corps.
Heaven forbid the Hokage even found out how the Yondaime's child was being reared.
