The Evil Man in Soul Society, Got the Demon Sword Muramasa at the Beginning

Traveling through the Shinigami a hundred years ago, Kuchiki Amasawa obtained the evil-doing system. As long as he does evil, he will be rewarded. Therefore, he deliberately provoked a battle of death and won the demon sword Muramasa as a reward from the system. However, he was captured by Kuchiki Ginling and put under house arrest for a hundred years. As the hundred-year deadline approaches, it is almost time for Aizen to defect. "Stupid brother, can you really defend the honor of the Kuchiki family?" "Matsumoto Rangiku, this is evidence that Ichimaru Gin harmed the Shinigami. You don't want me to submit it to Room 46!" "Miss Yoruichi, you helped Urahara Kisuke escape into the present world. Do you think no one knows about this? You don't want Urazono Store to be exposed!" As Kuchiki Amasawa did evil in Soul Society and gradually developed his own power, this also aroused Aizen's awareness, but he did not pay too much attention. When Aizen faked his death, he used Kyouka Suigetsu to deflect everyone. At this time Kuchiki Amasawa** came out: "My sword is called Demon Sword Muramasa. It is a Zanpakutō that can control any ability. Do you think I will be caught in the mirror?" This novel and its characters are purely fictitious.
