16(Crossover)

An Au where Akutagawa run away from the Port Mafia after one of the 'final' fights but no one was sure why as they knew Akutagawa was a loyal person and wouldn't abandon Gin.

Gin knew why her brother run away but never opened her mouth and acted like a grieving/furious abandoned little sister in front of others until Mori and the others slowly gave up on looking for Akutagawa as they could not find him(how they did this, is up to the writer but since I like Ango maybe he could have helped Akutagawa with hiding were he would be).

Akutagawa had been born a girl but early on he knew he was in the wrong body besides knowing how men went after girls(no matter age) in the streets so he hide that he was a girl and once he joined Port Mafia he was able to transition.

No one really knew about this, not even Dazai(maybe he could have an idea but never really got a confirmation), and Akutagawa so no reason to share it but after the celebration of winning against the 'bad guy', Akutagawa had found himself in someone's bed naked(who he slept with, is up to the writer) and a few weeks later he found out that he was pregnant.

He had thought about aborting the baby since the life he lead wasn't a good one for a child but he found himself unable to do it so he and Gin had created a plan for him to run away from Yokohama and be able to raise his future child for as many years as his sickness let him.

A few months after Akutagawa run away, a young baby with two coloured hair and eyes was born in another city who Akutagawa felt himself fall immediately in love with.

The baby was named Haruka Sakura as Akutagawa wished him to have a better life then him and those were names he and Gin always liked(besides Akutagawa's new identity being as Haruka Ryou).

Akutagawa knew he wasn't the best to raise a child but he did the best he could to raise Sakura unfortunately he could do nothing against people who treated his child bad because of his different coloured hair and eyes besides telling Sakura that he was beautiful and that Akutagawa loved him more then anything else in the world.

That had been enough for Sakura to handle the dislike, until Akutagawa succumbed to his sickness and Sakura was left alone.

Gin(or Ango) was informed of Akutagawa's passing and wished to go to her nephew's side but she knew her brother did not want Sakura involved with Port Mafia or Yokohama in general so she sent some money to Sakura and various places/cities he could move to to start a new life.

Sakura's story from this point will be the canon one but with him keeping Akutagawa's love for him as one of his motivations or reason why he somewhat kept away from others.

Would anyone from Yokohama find out about Sakura and Akutagawa? It is up to the writer but an option would be a member of Furin having an ability and Japan government asking some people from Yokohama to make sure said person wasn't abusing its ability and somehow they met Sakura and noticed how he looked so much like Akutagawa.

Anything else is up to the writer.
