Summary: And Zelretch sent Shirou to another dimension for fun. "Fuck you Zelretch ..." And Shirou woke up with a small body full of wounds and his red hair again.

A/N: I only made it because I wanted to write and channel my imagination. And here parental Dazai and child Shirou.

That afternoon was a quiet Tuesday. Many people passed by and left their offices to return to their homes. But that afternoon at the armed detective's office, Dazai Osamu, a detective there, was sitting in a long chair that was usually used to receive guests. With earphones attached to his ears he sang.

"Suicide, suicide mustn't be done alone ~"

"Dazai, do your job quickly! Don't be lazy!"

"Sorry Kunikida-kun but I have finished it~"

The blond man named Kunikida narrowed his eyes then examined the papers on his desk. Kunikida not finished saw all the files, Dazai's cellphone rang.

"Moshi Moshi, Dazai here ~" and the Dazai began to smile.

"Alright, I'll be right there. Thank you for the notification." Dazai closed his cellphone and immediately took his brown robe.

"I went first Kunikida-kun."

"Where are you going?" Kunikida asked curiously.

"To hospital, i have to see my son~" The mouths of all those who heard it were wide open.

"Ha?"

- at the hospital-

"Hey how are you."

"I think it's better, thanks Dazai-san."

"I see, good for you, Shirou"
