Ever since you were young, you were always told you looked very alike to your brother, Dazai Osamu. It was something you began to resent once you came to the realization that it was all you were known for. Any previous talent or trait about you became forgotten after people started to make the connection between you and Dazai. He was so incredible, so intimidating, so intelligent, so... loved. But he always cared less for that sort of stuff. And even though he was your brother, you didn't have a single clue on why he was so reluctant to give into the support that seemed to come to him so easily. If you were given a chance to be seen as your own person like him and given the praise he had, you'd be basking in it, regardless if you became drowned with such petty little desires.

But like always, you weren't even second best. You were Dazai's shadow, the sand in his ocean. Soon though, the strange boy of the name Akutagawa came to you like a dog to their owner. He was a subordinate, unluckily in the hands of your brother. Bruise after bruise, scab after scab, scar after scar, he always came back with an incorrigible wish of wanting Dazai's approval. You pitied him, as you've known your entire life that your own brother didn't even encourage you.  Still, he was determined for his wish to come true, so what did he do? He went to Dazai's akin. You.

Like an unwanted pet, he always brings you the dead bodies of his victims, hoping for some kind of gratification, or even acceptance at the very least.

"Look, I killed them all by myself." He points out the obvious, his gaze switching between the grotesque scene and you, eyes filled with anticipation.
