Reincarnated as The Main Character Little Sister and....I Just Don't Wanna Die Again

Reincarnated as little sister of the one main character from a game, our main character tries her best to not affect the story but the perfect ending need her dead! 'There's is no way that I gonna let myself die again!' Watch our main character as she meet many strange people, see more story behind the main story from the game while clearing her brother obstacle and accidently killed one of important character? 'Eh?.....w-what should I do?!' This is my first time write a story, so I welcome feedback and suggestion. I would make many mistake and many repairing in this story as I improve myself. Thank you (^_^)/
