All the events until this point let to Rukia's chase by Renji and Byakuya, Ichigo vs. Renji took place.
Like in the beginning.
(Some of this info will be used as flashbacks.) :3 Otherwise this is the story so far.
The Return of Isshin Shiba:
The former Captain of the 10th Division!
It was raining, Ichigo's blood ran through the floor. His eyes felt heavy. He did his best to grab onto the bottom of Byakuya's ShihakushÅ.
...
There was an exchange of words between the rookie and the Captain, but Rukia didn't pay attention to it. She placed her hand on her belly, wondering if that night was a mistake. It had been two weeks since she heard the news. All of those days that she felt sick was for one single reason, she was pregnant.
...
The child will be born without a father if her brother kills Ichigo. 'What do I do?' Rukia asked herself. No one knew about the child except Urahara and herself. She believed that the Gigai was the problem, that maybe it was broken, but that was not the case. It was that night what cause everything.
...
"It seems that you won't be needing that arm..." said Byakuya ready to cut the young man's arm, with his Zanpakuto. He didn't even had remorse in his eyes.
"Nii-sama! I ...I'm ...pregnant!" yelled out Rukia. Which immediately, stops Byakuya's actions.
Renji was the one more shocked from all of them. His arms fell, letting Rukia go. She move towards Ichigo, Renji was paralyzed. Rukia had chosen this man, after everything they had gone through? But why? Why him? Maybe it was because he resemble that man.
Byakuya didn't move at all. 'So this is the man you have chosen Rukia.' He thought to himself. No one was making a move.
"You're pregnant?" Ichigo exclaims, a shocked look on his face, he didn't know this. Now he questioned Rukia's friendship. Rukia never told him this, that she was carrying his own child. And she probably would never done it.
"Yes," replied Rukia with a calm voice. "I have been pregnant for weeks now, Ichigo. I'm sorry ...I didn't know how to tell you." Rukia burst into tears.
Ichigo now wished he had fainted, from the blows that he received earlier from Rukia's brother.
"I'll do whatever you say, nii-sama. Please. I'll go back and face punishment. Just ...don't kill him." Rukia begs to his brother.
Byakuya had not yet found the strength to tell Rukia about her sister, Hisana. But he knew that her step-sister was now making the same mistake he did long ago.
"Then is decided." Byakuya separates from Ichigo, and walks away from him passing by Rukia's side with his eyes close.
"Captain ...are you fine with this? That bastard has tainted the Kuchiki pride!" Renji clenched his teeth, he approached Ichigo and lifted him from the floor by the collar of his ShihakushÅ. He smacked Ichigo into the wall nearby, looking at him face to face.
"Why did you do this? Answer me!" Renji fearless yelled at him, ignoring the presence of his Captain. Ichigo was to weak. He couldn't answered him. The blood dripping from his forehead, almost cover his vision.
"Renji stop! It was my fault, I chose this path...I chose him..." Rukia stated, before lowering her head facing the ground. Byakuya looks at Rukia and noticed her sister's love towards the man.
"Lieutenant Abarai, you're acting on your own personal feelings towards Rukia. I recommend you stand down, before you force me to take action." Byakuya said with his calm voice. He didn't have a choice but to follow the rules, he made the effort to save this boy from the wrath of his Lieutenant, for the sake of his future nephew, that his step-sister was now carrying inside of her. This boy should not grow up without his father, but this was not his choice to make. It was up to central 46 to decided.
Renji steps down from what he was doing. Frustrated that he couldn't kill the man that ruined his future plans. He release Ichigo, letting his body fall to the ground.
A shadow passed by Renji's side, taking Ichigo's body from the ground, Renji couldn't even react to it.
"What do we have here? If it isn't the Kuchiki brat. As much as I would like to see you kick my son's ass, I can't allow that right now. I see. So, you became a captain, congratulations." said the man carrying Ichigo over his shoulder where he was wearing the 10th Division Haori.
He had just arrived, interrupting their meeting in the process.
"It has been a long time. Captain Shiba. So this is where you have been hiding all this time." said Byakuya as bored as ever.
"You're. The ex-captain of the 10th Division, Isshin Shiba." This revelation left Renji Abarai in shock for the first time in many years. 'If this is true then that brat over there, comes from a noble family as well.' Renji thought to himself.
