          _{As a child of only five years old, and despite how his intelligence is starting to shine, he still is a child, after all. So seeing Kasuka’s blank expression triggers a normal reaction.}

                 _{“Why do you look so sad?}

                         _{Sadness isn’t good y’know!}

                                  _{People cry when they are sad,}

                                         _{and it makes me want to cry too!”}

    How strange, that a mini-Izaya would say that he looked sad. Kasuka didn’t think so - in fact, he thought he looked blank enough that that would be all he was considered. A blank slate. This was the first time he had been dubbed as sad.

      ”I’m not sad.
        And you don’t have to cry.
        There’s nothing to cry about.“
