For some reason Tamao doesn't remember the name of his village of birth, he only remembers the name of his old school, Suzuran, because the nickname 'The Monster of Suzuran', has followed him his whole life.
Tamao has very little memory of his old life before he started shcool. But he know that his mother and father were respectful shinobis, and fought for their village during the Third Shinobi World War. Tamao was five years old when he saw his father get slaughtered in their own home, by some shinobis from Iwagakure. The symbol on their forehead was burned into Tamaos memories for couple of years, and revenge was on his thoughts.
A couple of years later, Tamao started to go to school. His mother did not allow him to go to a ninja academy, so he went to a school where they only teached 'normal' subjects, the Suzuran school. Due to the war, the school didn't have enough resources so they had trouble with the kids. The school was know out in the country, and the shinobi world, as the worst school there is. The school was filled with different gangs with different leaders. The biggest leader, usually a senior year, had controll over the most classes, and was know as the 'True King of Suzuran'. They became leaders over a gang by fighting the leader of that gang, and the winner is the new leader, and that gang joins the new leaders gang. Tamao entered the school, with the thoughts of revenge for his father. His goal for this school was to become the 'True King of Suzuran'. He was a merely seven year old, with a obsession to become the 'True King of Suzuran'. In his first year he was laughed at, and gained no respect, but through the following years, he became bigger and bigger, and his gang kept growing. Some of the fights between his gang and some other gang were often very bad, and he has witnessed alot of lifes getting lost, and he have self taken some lifes to obtain his goal. After his sixth year on Suzuran he became known as 'The Monster of Suzuran', due to the blood he made his opponent shed, and the lifes he had taken during his fights. In the year before his senior year he had obtained his goal, he became the 'True king of Suzuran'. After countless fist fights, his mind finally started to get together. Things changed, and he grew up and started to think about the things that were best for himself and his mother. When he was eighteen, he and his mother left the village to look for a better life.
The first village they came to was Konohagakure. The rumors about 'The Monster of Suzuran' had spread, and the villagers knew that they would come, and they did not arrive to a people with open arms, but rather a locked up people, who knew how to give those cold and empty looks at 'Monsters'. Tamao and his mother were allowed to talk to the hokage, and Tsunade-sama had a personal talk with Tamao, and she could feel that he had changed. She had never talked to him before, but she felt that the aura around him now, was very calm and relaxed. They were allowed to stay, and things only went upwards from there. The first person Tamao got to know in the village was Asuma. Asuma caught him surreptitiously smoking behind one of the shops, but promised to not tell his mom, because Tamao was really afraid to let his mom down, but the smoking was a habit he have had since the early years of Suzuran. Tamao found it hard to make friends in the beggining, because the parents wanted the kids to stay away from 'The Monster of Suzuran'', but after a while there were someone brave enough to ask Tamao about his past, and he reveald everything to this person, who later became one of Tamao's closest friends.
After Asumas death, Tamao decided he would become a shinobi in the honour of Asuma. He made his mother learn him the basics of ninjutsu, and he was allowed to take the academy test, without having to take the whole course, and then he became a Genin. During his training with his mom, he found out his chakra nature was fire, but his mother refused to teach him anything of this. After some more training, he found out that had the chakra nature of earth too.
And now Tamao is on his way to become a great shinobi, and make Asuma proud.
