As the title says, Akutagawa Ryunosuke was brought up by the swordsman fusanggami who had a profound knowledge from childhood.
The setting here is that Akutagawa was not picked up by Dazai. When he was 6 years old, he went to other worlds and the world of Touken Ranbu because of books, and Gin also wore it (actually, he wanted to see what Akutagawa would be like without meeting Dazai).
After Akutagawa traveled through time, he was picked up by Anzai Honmaru's sword and became their judge. The sword men slowly relieved their knots in their hearts. Akutagawa also grew up and signed a long-term agreement with Shimai.
16 Years later, Akutagawa and Honmaru, who are all under the sword, travel back to Yokohama (divided into two world lines, one is the world where Akutagawa's main drama develops, and the other is the original world without Akutagawa)
Akutagawa here is a superpower + a master of swordsmanship. He has a naturally dark personality and a poisonous mouth. His physique is still relatively weak, but because it is effectively controlled, it does not have a big impact?
The characters and everything else will be completely ruined, and the plot will all depend on editing and not follow the original plot.
Akutagawa has long hair here, but his 'ears' are still there. His dressing style is more ancient. Please refer to the year of the swordsmen. The supernatural power works on the black cloak. He is taller than Fumino Akutagawa.
Silver has always been with her brother. She is a gentle and powerful Nadeshiko who was brought up by a song fairy. She is very good at swordsmanship.
... There is a problem with Honmaru's time and space converter, and he often teleports to other worlds during expeditions.
Purpose: See how life is different depending on the people you meet
