You were Dazai Osamu's sister.

It used to be you and him against the world, but... Then he left when he was eighteen, never looking back for you.

How could he leave the little girl he called his baby? You never understood.

But, as you walk in the cold winter streets of Yokohama in your mafia attire, you look through a cafè window and see him.

He looks healthier, he's joking around... You can't help but feel envy.
