Shifumaru/History

Past as a Shinigami
Shifumaru was a very intelligent Shinigami and felt that he was part of the 12th Division. Unfortunately, there was an error with his Shinō Academy's papers which led to his candidature to the 5th Division. Shifumaru didn't like his Division much and was very quiet and solitary, because of the feeling of incompability. He secretly set a small laboratory in his bedroom to make scientific experiments. When Shifumaru heard of the betrayal of Aizen, he went mad and escaped from Soul Society. He was later caught by the 7th Division Captain and Lieutenant (Sajin Komamura and Iba Tetsuzaemon) and went to trial with the Central 46, where he was exiled to the Living World with a tattoo that forbids him of talking about Soul Society or any information about other Worlds.

Living World
In order to live with no restrictions, Shifumaru went to the misterious organization Xcution and asked them to remove his seal and to break his Zanpakutō. Currently, Shifumaru is prived from his Shinigami powers forever but can talk about that subject. He asked them to teach him to use other powers in order to fight when needed. He learned his Fullbring along with Riruka. Shifumaru candidated to Science teacher due to his knowledge about science. He used that job to buy a new house (he was renting an appartment with his brother). He now fights Hollows and other minor enemies in the Living World.
