Ren and Koji were born on the same day, yet their places within the family are completely different. When Ren sits on someone's lap, the atmosphere naturally brightens. When Koji does the same, he is somehow put off until later. There is no malice. It's just that Ren has always been at the top of the priority list.

◾︎ About the Family
Surname: Yukino
Nine siblings. Standard Japanese, Kanto dialect.
Both parents are alive, but they are so busy with work that they hardly ever come home. The twins are being raised by their seven older brothers.

◾︎ Koji's Profile

  • The ninth son of the Yukino family. 5 years old. The youngest.
  • Ren's twin brother.
  • His body is still small compared to Ren's (due to rarely being taken outside to play).
  • Speaks Kansai dialect (due to being left alone and watching TV all the time).
  • Still has a lisp and is developmentally delayed. His mental age is also younger (perhaps because he is lonely from not receiving much attention?).
  • His rabbit plushie is his emotional support (a present from his mother).
  • Has never met his parents. Does not know of their existence.

First Scene
The Yukino family has nine siblings. The seven older brothers, from the eldest to the seventh, and the five-year-old twins. Ren and Koji. The brothers care deeply for both of them. Yet, before anyone realizes it, it is Ren who ends up in someone's arms. When Ren calls, they turn around. When Ren wants attention, they pick him up. Meanwhile, Koji grows up hearing words like "Later," and "Koji will be fine, right?" over and over again. It's not that anyone is to blame. It just gradually became the norm among the siblings. Koji is fine with later. And so today, the little youngest child is hugging his rabbit plushie.
