Dazai's Colorless King Development Plan

On the tenth day of Osamu Dazai's defection, in order to avoid being pursued by a certain port company, he ran from Yokohama to Tokyo. The Shinkansen he took arrived at 11 o'clock in the evening. In the unfamiliar crowd, no one knew his former fame, Osamu Dazai sat down on an empty bench obediently, catching up on his short sleep like every wanderer with nowhere to go in Tokyo. ... At three o'clock in the morning, he was awakened by the movement of the blanket. When he opened his eyes, he met the green eyes of a fourteen-year-old girl. Then Osamu Dazai was taken back home by a pair of well-meaning mother and daughter (with a reluctant scarred-faced man and a child who was not there so had no say) and lived a strange and peaceful life. A few months later, seeing that the time was almost up, Osamu Dazai prepared to use the intelligence to hook up with a certain officer who could successfully clear his name. After he said goodbye, the family (mainly the girl, her mother, and younger brother) happily celebrated him and strongly requested to help him buy "decent formal clothes that are enough to cope with the interview of his future boss." Okay, okay, meeting 3/4 of the bad and good families can be regarded as Dazai Osamu's lucky success? However, because the child had to go to school, the father had to pick up and drop off the child, and the mother had to go to the mall for shopping. In the end, only Dazai Osamu casually accompanied the girl to choose new clothes that suited him. When everything was peaceful, beautiful, and going on the right track, the big explosion caused by outsiders, killing and injuring thousands of people, suddenly occurred. In an apocalyptic scene where the sky was dark and buildings collapsed, Osamu Dazai saw blood that was familiar to him - overwhelming and soaking him to the skin. Ah, it's her blood. The next moment, the colorless King Sword rose from the sky. And Osamu Dazai is the first clan member of the new Colorless King. Good news: You don't have to worry about clearing your name, you're already a clan and you'll be ashore. Bad news: ... The wonderful family that took him in was destroyed. Osamu Dazai felt that he had to do something - this was considered the right thing to do by the one who saved people, right? Tips: 1. Bg, Osamu Dazai x Chie Umeshima. The age difference between the male and female protagonists is four years, and they were 18x14 when they met. They are both underage in the world view. The heroine has a peculiar personality. In the later stage, she made Osamu Dazai very anxious to deal with the confession of his uneasy conscience. 2. The world view is very mixed. I have a lot of private settings and changes to the timeline. There will be OOC. The heroine's parents are Megumi's parents. The plot of Odasaku and Megumi's mother's death has not been changed, but it may be changed later, so it doesn't matter what is written. 3. Although he is a king, he does not have many clans. He may just poach some corners here and there, mainly on a daily basis. But if Yixiang is removed, Lixiang will have his own life. The one currently scheduled is Jing Hua, and the others will be left to chance. Concept: Love is the greatest magic in the world
