I Want to Be the Protagonist of a Shounen Manga and Open a Master House in Demon Slayer World

Please collect it! Morikawa Mio, who lost her memory, had no relatives in Kabuchō. Fortunately, she was taken in by Toshi's mother-in-law and worked part-time in return. During her part-time job, she witnessed many times the Wanshiwu trio upstairs stumbling to solve the commission, and finally awakened some memories—— It turns out she is the protagonist! … "... I would like to take the liberty to ask Yin-sang, who is the protagonist?" "That is to say, the protagonist of "Silver O" is obviously my queen, Aru!" "How could someone recover their memory and think of this first! Could it be that what you have engraved in your DNA is such an insignificant thing?!" Faced with the unbelieving attitude of the trio, Morikawa Mio waved her hands and said that she generously forgave them, "This is the protagonist's demeanor..." Trio: "The protagonist is so handsome!!" Although Morikawa Mio claimed that sooner or later she would replace the Master House trio as the protagonist, but as her memories flashed back from time to time, she discovered that she was a high school girl, an otome game controller, and a two-dimensional rotten otaku, but she was not the protagonist. Until one day, she fell into a large hole that suddenly appeared on the road. When she opened her eyes, she was already in the Taisho era of parallel time and space. After realizing that she had traveled through time, Morikawa Mio's first reaction was—— A good opportunity has come! In this timeline where there is no Master House, she, Mio Morikawa, wants to build her own Master House and become the protagonist! Not an employee, but the boss! A beautiful woman who had suffered domestic violence came to her for help with her child in her arms. Morikawa Mio enthusiastically found a good place for her to go to the All Things Paradise Church. The villagers at the foot of Fujisei Mountain were troubled by the screams coming from the mountain from time to time. Morikawa Mio quietly followed a young man with flesh-colored hair into the wisteria forest. A pair of children disappeared one after another on the Mugen Train. Morikawa Mio took the child's portrait and enthusiastically embarked on the train that restarted operation. There are many more commissions...
