Japanese Literature
"I decided to kill my older sister for a peaceful life." Mayu Kuraishi, born in March, and his older sister Rin, born in April. Both were born close to each other, so they entered the same high school as they were in the same grade. In spring, when Mayu became the second year of high school, he plans to kill his older sister. Although she is a beautiful girl that everyone can look back on, she is actually mean and cruel. She has been repeating problematic behavior such as bullying since she was a child. How about the trial and error of the younger sister, who has always dreamed of breaking up with the "poisonous sister" but has been defeated? And what is the crime that the younger sister holds? This is a story about being released from assumption and going to freedom.
