Age 0 to 6; childhood years
Careless play and surprising realization
Sutemasu was born 28 years ago in a hospital in the middle of Kumogakure. While her mother was not a shinobi, her will and strength throughout childbirth could've made her as strong as, or stronger, than most shinobi. The child labour was tough and required a lot from Sutemasu her mother. Not to say that this is a sob-story about how she lost both her parents - no, as you will recognize in her story, despite what she's been through she has never had anything that bad happen to herself.
Her early years were spent mostly doing child things. She usually spent her time playing around with other children, until she became 4. From that point on, naturally as all the other children, she became more aware of her surroundings, the meaning behind the word shinobi, and the jobs that a shinobi was supposed to do. When she was six, she became interested in becoming a shinobi herself. Not for the obvious reasons, namely that it was 'cool' to be a shinobi according to many children, but more so because she enjoyed the kunoichi classes which included flower arrangement and other such things.
Upon enrollment she spent less time with her mother - who ran a flower shop - and spent more time with her father, a Kumogakure jonin. However in order to earn her allowance she still had to work in the flower shop, producing a strong bond between her and both parents.
Age 6 to 13; academy years
Study hard, play harder!
In her academy years, Sutemasu spent a lot of time practicing the shinobi arts, especially the kunoichi arts. A lot of time and practice went into ninjutsu and such, while a smaller but still proportionate amount of time was spent in the books to learn about theoretical stuff like tenketsu, chakra control and shinobi history. While she was a good student, she was never one to stand out too much even if she was capable of much more than she let on. She was shy and reserved, though she wasn't one to get bullied or let herself be teased - she could stand up for herself. But her general likeability made her a small target, and she got along with almost all her classmates.
Besides studying, she also spent a lot of time playing. She was acquainted with her many classmates outside of school as well and especially in the early years of the academy, she spent a lot of time outside playing shinobi games and doing general children stuff. When she became older the games changed, of course, and she was more frequently asked to help in the shop. Her group of friends that she frequently hung out with became smaller, but more tight knit, as is normal. It seems that even in a shinobi academy you can't stop clique's from forming.
Age 13 to 15; genin years
Time to work, time to help!
Her time spent as genin were perhaps some of the most entertaining years she spent in her life. While some would look back on the academy and wish they could be there again, Sutemasu was excited to begin working as a genin, doing missions and helping people. Unlike the current generation, she was a genin right after Sasuke and Naruto more or less 'saved the world' and then died. There was still a carefree attitude around, the idea that friendship was the most important thing. So she did not have to dig trenches or do anything like that.
She genuinely spent her time helping people with small tasks, and missions that were barely dangerous. It were more or less the luxury years of her career as a shinobi. It was during that time period, near her fifteenth birthday, where her father decided to retire. He remained active as a sensei within the academy, but his fighting years were over. At least, unless the village required him for it's defense. It seemed to make more sense to make place for Sutemasu, giving her a spot to earn the family some honour. And it would be a shame after all if he died during a mission now that he had a wife and a kid.
Age 15 to 21; chunin years
Maybe the shinobi life isn't that cool..
While she became a chunin with a remarkably good chunin exam, she soon experienced that the life of a shinobi was, perhaps, not as rose colored as she'd imagined. Once her and some of her friends became chunin, they were sent on more dangerous missions. Many of them did not make it back alive, and in these six years she lost many of her friends.
She became a bit more held back and reserved in her personality, becoming more quiet, timid and possibly showing signs of a slight depression. While she never developed anything serious, she was apparently touched deeply by her losses. At age 20 her father died of implications from an old wound that got infected, leaving her and her mother behind. The funeral was respect worthy, and after a small time spent away from the shinobi force, Sutemasu returned to her duties.
Age 21 to present day; jonin years
Teaching kids can be fun, too.. Right?
A year after her fathers death she was promoted to the rank of a jonin, making her a sensei to a team. While she didn't receive her father's headband like she would've wanted, since it was buried with him, she did receive her father's flak jacket. Her first team was a rather rowdy team but due to her natural charm and likeability she managed to subdue them and form them into shinobi that were worthy of the title of chunin. She led them from genin to chunin, with the recent exams being an ending to that chapter of her book. Currently she is on stand by which means she is mostly performing missions with other jonin. However, she has been alerted by the raikage that she is expected to return to her duties as a sensei, this time leading chunin that are already capable of a lot.
