Kamiyagawa had not previously experienced the red tide from Marine Country.
Now that this disaster has struck, he can deepen his understanding to some extent, which should help in addressing the red tide later on.
However, the timing of the red tide's arrival could not be worse, coinciding exactly with the election night of the Sea Country Lord, causing panic among the residents of Crab Island.
In the midst of the chaos, several gigantic Samurai Crabs made their way sideways through the jungle from the outside.
One of them spoke to Kanihime in a deep and sonorous voice.
"Lady Kanihime, the mermaids... the mermaids have come with the red tide."
Kamiyagawa had previously speculated that the mermaids would launch another attack on Okitsu Island before the establishment of the King.
This was also the reason he was unwilling to leave Okitsu Island in recent days.
