This is a fan fiction. I do not own Bleach in any form.
I do hope you will enjoy it.

Isshin and Ichigo were both born in the worst part of Rukongai. The level headed Isshin always had problem with his battle hungry brother, Isshin was the weird one between the two. All the members of the Shiba Clan were violent and prone to respond harshly to any challenge. Isshin was the most level headed member of the clan, and Ichigo was the very embodiment of the clan way of thinking, the clan was known to be one of the best fireworks makers ever, and Ichigo was particularly gifted, fire just seemed to love the guy.

Ichigo and his brother had just finished making something for a merchant and when they left the place they saw a group of people doing something they would regret. They where making fun on how boring her birthday would be since she and her adoptive father were both flat broke. Ichigo just had to step in, there was something he hated and that was seeing a girl cry.

"So you morons want to pick a fight? well congratulations are in order since you picked it with me, and before you even ask it's because you made fun of her. We all are as poor as all hell, and you make fun of her because you think you are richer than her. You are nothing but cowards. Worthless, stupid, weak, pathetic and ugly cowards at that." The group of fools was know to have one thing that they were proud of and that was their looks. They looked like they were part of a band of models. But Ichigo insulted that one thing that they could not stand and let it go.

"Who are you calling ugly!?" They all jumped and tried to rushed Ichigo. "Hook, line and sinker." Isshin just had to say it as the group of bullies jumped right above where Ichigo had thrown a paper bag. With a click of his finger the bag blew up and in an impressive explosion the group of bullies where caught in it. All four were badly burned and scarred Ichigo walked over their injuried bodies, giving each a downwards kick to the family jewels.

"Don't you worry Yachiru, I will make this birthday your very best, don't you cry. I bust out my A class fireworks and you will have the best birthday ever." Yachiru actually smiled at what her friend did. It was a big secret but Ichigo and her adoptive father like to fight and Yachiru enjoyed seeing them have so much fun together. She even had a nickname for him. "Ichi, do you mean it? Thanks, Ichi I will tell dad about it." The young girl ran towards her home.

"If you are done with your friend, can you help me take care of the group of idiots that you just injured." Ichigo told his brother that they didn't have anything sharp enough to finish the job. "I mean come and help me treat their injuries, what you actually want to kill them?" Ichigo told him that he was actually disappointed in his bomb, it was supposed to incinerate them but it only cause minor burns.

Isshin actually could not believe his brother words. He looked at the idiots on the ground. "You call this minor, I don't want to see what you call major burns." Ichigo helped his brother for him and it gave him a few more chances to give the morons a few well place hits. "I asked you to help me heal them, not beat them up." Ichigo told him that he was waking them up, he did the same thing to him for years, when he slept too much.

"Don't remind me, I still wake up from sheer fear of your wake up calls." Ichigo told him that he should thank him instead of wasting his time with pukes like them. "Life is precious Ichigo, they simply are too young to know any better, we must give them a chance to learn." Ichigo was not going to sit there and hear his brother sermon again. He told him he better leave and get something to eat, or he would more than likely have to beat the idiots again, and this time he was not going to take it easy on them.

Isshin told him to go and eat something, and bring him something in a little bit, it would not take long for him to heal them. Ichigo left and gave each a nice lump on their heads to remember to avoid him. "Stupid brother, compassion will only get you killed. I wanted those stupid bastards dead for making Yachiru cry." Little did he knew he was being watched. The commander of the soul reapers had heard rumors of the two brothers that were as different as night and day.

One brother was a born killer, and the other a kind caring soul. It was clear that the one headed towards their living space, was indeed the killer and the kind one was tending the people his brother just admitted having failed in killing them, and all because they made a girl cry. One of the soul reapers made his way towards Isshin and told him he had better ways to heal, he used his powers to heal the people that his brother had injured.

"My friend and me where sent to invite you into the seireitei and be given the chance to save souls from the threat of hollows. I know you would want to save people, so will you accept?" Isshin told him he would not abandon his brother. He was his only relative and he would not abandon him, specially if he was to be a soul reaper and live a comfortable life. He would not leave Ichigo and live in comfort by himself

"Don't worry about Ichigo, my friend is going over there and inviting him too. They will get along rather well." Isshin asked if his friend liked to fight? the man smiled and said that his friend hated bullies as much as his brother did, a strong sense of justice and he would never allow them to go without a punishment, but yes his friend loved a good fight.

Ichigo was just finished cooking the food he would take to his brother, eating alone was not his favorite thing in the world, so he would pack two lunches and take one to his brother, they always ate together after all. "Look, I don't know who you are, but I am rather busy. If you want charity go talk to that softy brother of mine." Yamamoto began to laugh. "No, I am actually looking for you Ichigo, or should I say the pyro fiend of Rukongai."

"Look as flattered as I am old man, I am busy if you want to talk move those fingers and give me a hand." Yamamoto helped him by packing the food he made. "Mind if I ask why do you put so much effort cooking this food?" Ichigo told him he could not find anything that tasted good so he had to make due with what he found. It was for his brother, why wouldn't he put some effort in cooking their food?

Yamamoto liked the kid, it was almost funny that he called his brother a softy and it was clear he cared a lot about people. When he finished he went on and began to work on something else. "Well the food is ready, what are you doing now, Ichigo?" Ichigo told the old man that he was making fireworks for a little girl's birthday. It took him 10 minutes but he made enough fireworks to make that birthday something to remember.

He took both the lunches and the fireworks with him and left. Yamamoto followed, he wanted to see where he was going. "You know I could carry some of that." Ichigo told him that he would never make an old man carry that much, he could injure himself and then he would get yet another sermon from his brother, and he did not want that. Yamamoto laughed and found the entire thing rather amusing.

They got to a small hut and Ichigo knocked. A large man came out and he smiled. "Ichigo, want to fight?" Ichigo told him that he had to take a rain check on the fun, he was simply delivering the fireworks for Yachiru's birthday. "Karazaki, you know how to use them right?" The big guy smiled and told him he did. "Tell Yachiru a happy birthday from me, and we will fight again real soon, Karazaki."

"Sure thing Ichigo, I will tell her, and looking forward to us having fun." The large man entered the hut and spoke to someone, as soon as he did a young girl jumped on Ichigo's shoulder and gave him a kiss on the cheek. "Thanks for the fireworks, Ichi." Yamamoto was surprised that Ichigo crossed three districts so fast, and only to make a little girl happy. Yes, this Ichigo was a good candidate for his little project.

Ichigo began to walk towards where his brother was at. "I know where you brother is why don't you follow me. If you can keep up with an old man." Ichigo told him to do his worst. Yamamoto took off at high speed and Ichigo really had to run to keep up with him. When they reached the gates Ichigo was breathing hard. He asked how could an old man run that fast. "Accept what your brother will tell you, and you might just find out how."

"The old man must be losing it, what did he mean what my brother offers me? Isshin doesn't have anything to offer. If anything I have lunch to give to him." He walked towards his brother and saw that some guy with a really nice mustache was with him. "So bro, what gives? didn't you say you were going to heal the pack of losers?" Isshin told him they were healed and had been sent on their way to their homes. Ichigo told him he delivered the fireworks for Yachiru's birthday, Kazaraki was going to set them off.

"Karazaki always did care about his little girl, I bet she was really happy. As to what am I doing, this guy and the old man over there told me that he could train us to be able to save human souls from monsters. Ichigo could hardly contain his laughter. "Oh, sure two officers from the Gotei squads want to train two nobodies from Rukongai, get real. They only train people from noble clans, and ours is hardly what they would consider noble. The Kuchiki clan would sooner see us both dead, than be admitted for training and you know it."

The English look gentleman asked what could he mean by that. The Kuchiki clan was one of the most honorable clans there were. "Maybe I should introduce myself and my brother. I am Isshin Shiba, and this blockhead is my brother Ichigo Shiba. We are both members of the Shiba Clan, and obviously were born from different mothers, we both were born in Rukongai and lived together ever since our mothers both died."

"I see, a noble of the Shiba Clan went and had his fun with two women of Rukongai and you both are his illegitimate children. You both know of the Shiba Clan probably because your mother told you about your father. Sadly that is not an unknown thing here. As much as the soul reapers try to keep the order, we have too many things to do and too few in our ranks."

Yamamoto then came to them and said something that shocked them. "My lieutenant will train Isshin. and you Ichigo since we both have a fire affinity will train with me. If you accept and reach your bankai. You can be the first captains of a new division. We have nine so far, so you both could be the captains of the 10th and 11th divisions. So do you accept or not. I'll make it simple, just walk though that gate if you accept, but you must be able to open it yourselves."

Isshin walked over and tried to push the gate open but it was immensely heavy. "Hey could you tell the big lug behind the gate to stop pushing it, my brother will never be able to open it if he keeps that up." Both soul reapers looked at Ichigo, and they wondered how in the world could he tell that someone was behind the gate. "I mean it, stop pushing or so help me I will burn that thing down."

"All right, guard stop pushing." Isshin began to push the gate and it opened and he walked through. There was somebody that looked like a giant behind it. "Ok, Isshin step away from the gate." Isshin did not like the sound of that. "Ichigo, just push it, there is no need to burn the thing down you know." Ichigo ran towards the gate and with a strong push the gate opened and he ran through the other side. "Honestly could you do anything peacefully?" Ichigo asked where the fun in that?

The old man could clearly see that he was not going to have an easy job teaching Ichigo, "Well since you both entered then we start your training as soon as you get some sleeping quarters assigned and receive your training gear." Isshin was looking forward to it, and Ichigo asked that the sleeping quarters were no were near the Kuchiki Clan compound. Yamamoto promised that it would be so.

It took three years before their training was done, in truth they were ready after one but they wanted to be ready for anything. During their first year as soul reapers the two brothers did somethings that were considered amazing. Isshin had developed a technique to calm down his enemies, he even managed to calm down a menos and it was a gillian but it was amazing non the less. The Gillian became so calm that it even didn't bother to fight, it simply went back to hueco mundo without making a fuss.

Ichigo however saw the soul of a small child crying, and it was surrounded by 23 hollows each fighting each other for the right to eat her. Ichigo using only his zanpakuto who he found out was a spirit of fire, that took the shape of a beautiful young woman with long black hair. She was a very emotional, but considerate spirit. The shikai release for her was, Purify the world in you flames, Amaterasu.

With his sword release to the shikai level he killed every single of the hollows and sent the crying child to the soul society, where one day would remember the person who faced such dangers and thank Ichigo for saving her. She would eventually become his attendant and take care of his needs, but what was most astonishing was a secret. Only Captain Commander Yamamoto knew, and that was that Ichigo had achieved the bankai release and was simply waiting for his brother to be able to do it.
