Demon Slayer: I Have Incredible Understanding

[Hot-blooded and refreshing text + system + female protagonist (Nezuko, Kanohu, Butterfly Ninja, etc.)] The otaku Tang Yuan travels through the world of Demon Slayer: Kimetsu no Yaiba and gains an incredible understanding at the beginning. Just when he thought he only needed to play soy sauce and follow Tanjiro through the plot, he found that the world line had already changed and he had to shoulder the responsibility of slaying demons. Note: If you split the official version, there will be emotional lines for each person, and there may be some attachments to the Shura field. The plot direction of Fuji Assault in Front of the Mountain is similar to that of the original work. If you add some of your own settings later, it will go completely wrong, and some ghost settings will be added. Each character will be described if he or she stands in the column's camp. Of course, the most important perspective is definitely on the protagonist.
