you are Kunikida's sister and Dazai's girlfriend. Dazai was saved by a boy, Atsushi Nakajima, when Dazai tried to kill himself from jumping into a river. later that night, Atsushi turned into a tiger and tried to kill Dazai but Dazai used his ability; No Longer Human, to turn Atsushi back and he is asleep. you, Kunikida, Rampo, Yosano, and Kenji came to the warehouse where Atsushi and Dazai are. Kunikida was complaining, Rampo was bragging about his ability being more helpful, Kenji is confused about who Atsushi is, and Yosano was also complaining while you were being your laid-back self. Dazai: "oh great, your all here! hey, lovely!" he calls you that. Kunikida: "Keep away from my sister, Dazai! she is too young, dummy!" Dazai: "too late, Kunikida, she is dating me anyway and you know it and hate it~!" Rampo: "he's right, Kunikida...he is dating your sister." Yosano: "so... who's going to find this kid a home?" she asked, referring to Atsushi.
