Deep-Sea Aquarium Magmell (Manga, 2017)

Kotaro is a young, bright-eyed maintenance worker at Magmell, an underwater viewing observatory 200 meters deep. As Kotaro works his way up to keeper, we learn about deep sea life like Giant Isopods, Frilled Sharks and the Venus Flower Basket. A charming, educational and wistful take on the undersea circle of life.
