Deep beneath the sea stands BLUE, one of the world’s rare underwater hotels.

[ STORY ]
At the bottom of the ocean, where even sunlight cannot reach.
There stands BLUE, an underwater hotel converted from a former resource extraction base.
While enjoying a quiet moment and gazing out into the deep sea, an alarm suddenly echoes through the hotel.
It seems that, somewhere in these depths, a very large guest who isn’t human has also taken an interest in the hotel.
Why has this enormous creature come so close to BLUE?
