Ugh... for some weird reason the weather's been stifling hot ever since we entered this area of the sea, ay...

Kirishimaaa... what's going on heeere?

Underwater volcanoes are present under the sea around these parts. That's why the temperature can be a bit high...

It's one of those so-called 'oceanic hot springs'. AKA hydrothermal vents.

This feels so good dechiiii...♪

So rejuvenating...♪

To think we're forced to only float on top of the surface of such a hot spring...

...true that...

I admit, I would like to take a nice refreshing soak as well...
