Death begins. The super strong woman who once died on earth was reborn in the world of death, and became Gin Ichimaru's younger sister (pseudonym). Igurona, who was once the best at vivisection and was known as the "Crazy Doctor", is only allowed to plot against others. What kind of waves will she make in this world of death? (Note: My heroine is absolutely strong and never feels a trace of fear or fear. She is also not afraid of Big Boss Aizen and Big Boss Ichimaru, and she also plots against them. Therefore, I don't like to enter by mistake, and there is no male protagonist in this article, because this is one of the series, and the male protagonist is in other works. Part of the power possessed by the heroine in this article is borrowed from Kagura Mikazuki's power in Fairy Tail)
