Chapter 1 - Day 1

Youtuber Asagiri Gen tackles yet another ridiculous challenge for his fans - surviving on an uninhabited island. No one could have predicted the tsunami that hit. Barely struggling to keep together, he meets a person behind a mysterious smell that hit just before the wave did. Ishigami Senku needed a reclusive place to test the strongest most pungent smell artificially created. Needless to say, he wasn't prepared for the natural disaster either.
