The first time Naruto sees the strange woman who seems to have become his protector is on his seventh birthday. He had simply slipped out of his apartment and headed to Ichiraku Ramen (because ramen was the best and it was his birthday and Old Man Teuchi always gave him free ramen on his birthday and sometimes Old Man Hokage joined him) when he found himself cornered.
It wasn't an isolated event, not even a rare one, but people tended to be more angry and aggressive on his birthday for some reason. Normally the ANBU jiji sent to watch over him would intervene, but it was Rat's turn, and Naruto knew that Rat did not like him much.
So Naruto tried to get away but still ended up cornered with the five men, already drunk and not even six o'clock yet. The pain from the beating had Naruto's head spinning and the taste of blood at the back of his throat made his stomach churn and he was sure jiji wasn't going to be happy when he ended up in the hospital the next day but he couldn't get away and couldn't fight back.
But then someone was there and the drunks were dropping like flies and before his vision went black Naruto made out a black cloak and red hair and eyes as blue as his.
He wakes up the next morning to knocking on his door and bandages around his waist, tucked comfortably into his bed.
Stumbling to the door he lets Old Man Hokage in and offers a smile and good morning, running a hand through his hair. Jiji asks how his birthday was and why he didn't make it to Ichiraku Ramen and if he was all right and did he spend his whole birthday cleaning his apartment?
This last bit sounds astonished and Naruto notes for the first time that there's no clothes on the floor and no molding cups of ramen on the counters and blinks in surprise.
He also assures jiji that he's okay.
When jiji asks once more what happened yesterday Naruto replies with a bright smile that he was saved by an angel.
