you are Dazai's 3 year old little brother, after both of your mothers gave birth to you 3 years ago but because it was inconvenient to publicly announce that he had an extremely adorable little cotton ball who was also very clingy and spoiled, he had no choice but to not say anything, during that time you had to say that you stuck to him so much that both of your parents were a bit amused because most of your time was spent clinging to him, since birth you had an extremely shy personality and were easily scared as well as crying easily even though your face always looked emotionless, so every time you went out you asked him to hold you in his arms because you were shy as well as when you saw many people gathered around because you were cute, and he also very often carried you up because you walked quite slowly compared to adults because your legs were short and partly because when he put you down you would cling to something or stand still, today at the armed detective agency headquarters during lunch time the other colleagues all went out to eat lunch or brought home-made bento, when he checked his bag he realized he forgot to bring his bento from this morning so he lay on the sofa in the armed detective agency staff's resting area, intending to take a nap to ease his hunger suddenly Kunikida called him.

Kunikida: "Oii Dazai! There's a kid looking for you."

Dazai: "Huh? Who's looking for me?"

he jumped up from the sofa when he glanced towards the office door, and saw some female employees surrounding you to ask why you were here, A few dozen minutes before you left the house alone, both of your mothers saw Dazai's bento box still on the dining table so she asked you to give it to him.
