Yamamoto: "That soon??"
All the Captains tensed up when they heard this including Unohana who was providing treatment for Hitsugaya...
Sora: "At that time we may face, hit and run tactics before the war or."
Shunsui: "An immediate war!!!"
Sora: "Correct, but that for the future. We still have time for that, and for this problem, i'll do something about it. I'll try my best not to drag this in Soul Society."
As he said that Sora and Senna left from there leaving them behind as they watched walk away so carefree...
Yamamoto: "Sigh.... Mmnnn..... Captain Unohana take him to your Division for healing."
Unohana: "Yes..."
Unohana took Hitsugaya before vanishing from the room leaving behind all the others waiting for Yamamoto to speak as he was about to give orders for the 10th Division.
Yamamoto: "Vice Captain Rangiku Matsumoto, you are done here, return to your division upon further notice."
Matsumoto: "Yes...."
Matsumoto backed off without a second thought as her Captain was found and Yamamoto started explaining the History which was secret to most of them...
Yamamoto: "Kusaka Sojiro, he was in the same class as Tōshirō Hitsugaya and the two of them quickly became friends."
Yamamoto: "He had regarded Hitsugaya as a genius and strove to be better than him. He also swore his allegiance to Soul Society and worked hard to become a successful Shinigami, devoting his life to them."
Ukitake: "Oh, that boy??"
Shunsui: "It was recorded he died in their graduation exam..."
Yamamoto: "The reason he was deemed dead was that of his Zanpakuto, and not through an exam as he had come back alive then but in secret."
Yamamoto: "When Kusaka met his Zanpakutō's spirit in a cave, he met Hitsugaya there who had also met the same spirit. They were overjoyed to know that both of them had exactly the same power and their friendship deepened as a result."
Mayuri: "2 shinigami with the same spirit fascinating... It shows you, how much-hidden power waiting to research must be contained inside..."
Soi Fon: "Or they were gonna be incredibly weak for sharing the same spirit."
Komamura: "It would be unknown at this point if they would be weaker or stronger..."
Yamamoto: "However, the Central 46 members ruled that two Shinigami cannot possess the same Zanpakutō. By the ancient laws of the Shinigami, such a situation was not permissible."
Yamamoto: "Although neither Kusaka or Hitsugaya had intended to violate the law. Hitsugaya offered to abandon Hyōrinmaru instead of fighting Kusaka, but the council forced Kusaka and Hitsugaya to fight for the honour of bearing Hyōrinmaru."
Byakuya: "That's why Sora said it was the orders of the 4 Families."
Yamamoto: "It was ultimately Kusaka who drew his sword and charged at Hitsugaya, shouting that he wanted Hyōrinmaru for himself."
Yamamoto: "But that cost him, as it was never meant to be a duel to the death, but a test to see who would raise their blade first."
Soi Fon: "So what happened afterwards???"
Yamamoto: "Just before the battle was concluded, the Central 46 members ruled that Hyōrinmaru belonged to Hitsugaya and Kusaka was sentenced to be killed immediately."
Yamamoto: "Though no one had won at the time of the decision, Hitsugaya appeared uninjured, while Kusaka was covered in ice. Numerous Onmitsukidō members appeared and restrained Hitsugaya while surrounding Kusaka."
Yamamoto: "Several of them stabbed Kusaka and then dealt the fatal blow by slicing open the right half of his face."
Yamamoto: "Then his execution was kept secret and his academy records were destroyed afterwards. Almost no one in Soul Society knew of his existence."
Ukitake: "To think that he survived..."
Shunsui: "So when the Ōin vanished a few months ago was that it could give him new life in Hueco Mundo, since he appeared with 2 Arrancar."
