August's first s-class:Water

" The potion lasts until sundown, so everyone has to be back on shore before then to be safe." The boss's instructions were simple, find a chest, solve a riddle, get back on shore before sundown. Then August remembered this is Koma Inu, so there was bound to be some challenge. The contestants all drank the underwater breathing potion and dove into the sea, where August was immediately weighed down by his coat. The currents were rough and there wasn't much visibility. August felt his boots hit solid ground so he walked forward a couple steps and fired two of his revolver shots into the darkness.
