I Travel the World by Playing the Role of a Literary Giant

As an ordinary high school student, Chishima Aya has a secret. Every once in a while, she will be thrown into a different world by the system. She not only needs to play different literary roles, but also needs to complete various bizarre tasks assigned by the system. I just don't know why, but in her world, these great writers who hold pens in their hands have become armed characters in the system. Tentative world: Death God Dazai Osamu, hunter Nakahara Chuuya (will be added later)... Demining: 1. The appearance of the heroine will change into the literary character she plays, and her character will refer to the character of the character she plays. 2. The heroine's appearance changes, but her height and gender remain unchanged. Concept: The protagonist plays the role of a literary hero
