Wan! Chapter 19

If the Boy's Hungry (あの子がお腹を空かしたら,) is the 19th chapter of the Bungo Stray Dogs Wan! manga.

Summary
Amidst Atsushi's musings about how Yokohama is quite peaceful recently, he finds Kenji punching through the wall and demanding Tanizaki to bring him some food. Atsushi immediately buys some gyūdon for Kenji, much to their confusion on his behavior.

Dazai tells them the news about a strange disease that makes mild-mannered people go hungry and violent. Since the recovery according to Yosano is one-day fasting, Kunikida advises Atsushi to have Kenji fast for the day, though Atsushi informs them that he just gave Kenji some gyūdon.

As Kenji continues his aggressive cravings, Dazai and the others who consider themselves "mild-mannered" are wary that they might also contract the disease. Soon, Kenji begins stealing and eating their hidden candies and snacks from their desks, compelling them to get serious about the matter.

Until that evening, Dazai, Kunikida, and Tanizaki manage to restrain Kenji from his rampant behavior. As he comes back to his senses, Kenji asks why the Agency office is in shambles, unable to remember what had happened.
