Tetsu isn't the smartest person around, but she still has her things that she can be proud about. She could be a bit rude, even if so, she is nice to people she thinks are good to be around with. Warming up to people isn't good for her, because of her strong judgments and being a hot-head is more then worse.
Her past collides with her personality, making her much different from before. Having a need to win every challenge, no matter what the hardship. Her goals are mostly long term goals, but still, she has her short term goals as well, only they do not appear very often. Mostly being a control freak, she needs pretty much everything to go her way. Even if she doesn't know how to do things, she would still want to be the leader of the group. Her being a Leo is also an in with this, saying so that Leo's want the center stage and be appreciated a lot, also wanting to be a leader in any case. This sometimes causes her hardships with other people, since they see her to be not worthy of a leader. But she wishes to prove that she can do the right things, since her being young, no one really listens to her.
She doesn't like being left out, and mostly come along the lines of being cold to a person who affects her greatly in a negative way. Most of the time though, she would be laughing and joking around with people around her. She is a little clumsy and, odd in some ways. She is sort of like the opposite of a normal person, and her being offended, well, not very likely. She would fight back, even in a conversation. She could be a little stupid at times, but she makes up for it, she looks at the small things around her and outside the box, people do say she has a good eye in ways.
Even if she is not that smart in daily activities, she is great with childish things. Such as pranking, she loves to do it, and would do it all the time. They work, which surprises many people, even if she doesn't notice. Her having luck is very helpful for her, though she doesn't see that it is her luck, but more likely herself. She doesn't know where she gets her luck, but it never runs out for her. It's as of this, if it is boring, she will not interact. If it is something she enjoys, she would put lots of concentration among it. Even though Tetsu is usually quite dense in most cases, which often results in someone who is close to her hitting her, she can actually be quite observant when she wants to be, or the subject tweaks her interest. It is as it goes, and no one could change her.
Tetsu has a great sense of humor and usually smiles and laughs all round. Though at times, she smiles to hide whatever is bothering her so no one worries about her; those who are closest to her see right through it. But she doesn't have anyone close to her, so she would have no problems to it. Outside her world, she's just an ordinary, loud, hotheaded kid with a fierce will and a knack for getting into trouble. Tetsu is an avid eater with an appetite comparable to that of a pig. She loves to eat, and people sometimes wonder how she stays that skinny. But it's all thanks to the sports she does every day, even if she doesn't notice it. But that's just her.
Her personality is childish, even for her age. Being a sheltered child would have caused this, but still, she wouldn't care, since she doesn't really care about fashion or anything related to girlish things. Mostly being a punk around others, she doesn't worry, unlike other girls. She is also very innocent, even if no one can see it. She doesn't know anything about love or relationship or anything like that, and she may not know it either. She wouldn't care anyways, since she isn't intending to do anything else until she reaches her goals.
Tetsu had a very drastic change from when she was a kid till now. People may have thought that she could have been someone else when comparing to her younger self, but she isn't. Being born in a wealthy family, she was a bit spoiled. Though she acted nothing like a brat, actually, she was a very respectful and kind girl. She never really took advantage of the fact that she had more money, but more likely used it to help others. She was a rule follower, and a corrector as well, could be seen as a goddie two shoes. But her family was happy that they had a daughter like her, and she was also happy that she had nice parents. She was a lonely child, so they spent their time with her as much as possible, only that they were always on trips for their job so the family time wasn't usual. Tetsu was okay with this though, she understood that they needed to work, even though she does feel lonely at times. She was also sheltered, not knowing much of the outside world, since she didn't know what was out there in the world.
Those were all the happy times she had, and she liked it, even though there were a little troubles here and there. But everything changed one day, and that was when she became like she is now. No one saw this coming, but it happened. Her parents were home, the only time that were from the last few months, and she was happy to see them again. But it was midnight, and that was when the criminals lurk. And as of that, they were the ones, they set the house on fire. It was a joke for them, but a life or death situation for Tetsu. Luckily, she managed to escape the fire, but it was sad for her parents. She watched in horror as the house burned down, and immediately the fire engines came. She was sent to the hospital for any injuries, and all she had were some minor scratches and bruises, but nothing serious. It was a miracle, but she had to give away something for that, and she guessed her parents were something she had to give away.
From that day on, she hated every bad person, disgusted by them and wanting to do something. She didn't believe that killing was the choice for everything, so she decided to find out another way. But this also caused her to be a little more less trusting then before, and trust is something that is very important to her. She lived alone, but she didn't care, as long as she figured out who killed her parents. She also took lessons for fighting or weaponary, coming across to sports as well. She was going to do things her way to prove that she has the right answers, and that people can see that her answers were right.
