How to behead a serpent

An average fan of Bleach dies when playing Bleach Brave Souls trying to get a 5-star Hiyori. only to wake up on soul society 110 years before canon in the body of Hiyori. with a megalomaniac on the run, crazy experiments been done, a canon to maintain, and most probably the next Quincy war in the future. what could this Bleach fan in the body of a rage-prone loli do to survive? ---------------------------------- well, the first novel I will be writing. English is not my first language sadly but I will be doing my best to make this novel good, cause I have seen very few SI or OC novels of Bleach. hope you all like it! ----------------------------------- update will be at least 2 times a week if i am inspired.
