Do Hizashi and Nemuri ever show Shouta their cave? What does the cave look like, I'm so curious now
After weeks of peer pressure, he finally gives in and invests in a wetsuit and diving gear.
The mouth of their cave is fully underwater and is the only entrance. It has an area inside just about big enough to swim a few laps in, but if you go through a gap at the back and go upwards, you come to this air pocket that has some rocky ground. This is where Nem and Hizashi store their treasures, and where Nemuri sleeps a lot of the time (underwater, she has to keep moving to be able to pushing water over her gills, but on land she can use her secondary, human-type lungs to breathe, so she can relax).
Hizashi is like a kid showing his friend his room when Aizawa visits. He's very houseproud. It was his place initially, and Nemuri moved in when they got together. They've put a lot of work into making it homely. There's lots of decorations and stalactites and stalagmites inside and little shiny things that glint in the light that comes in through the tiny opening at the top that lets the air through.
There's another little shallow pool of water at the back of the cave where they can curl up and sleep without drying out.
