Koromo's specialty is "haitei."
海底撈月 – Haitei-Tsumo (Haitei Raoyue) “Scooping the Moon Out from The Sea” [luck type] - Basically when the very last tile you pick out from the wall is the tile you need to win.
Hence, the ocean.
@dixie93 Try Null scanslations. Link:

BTW, do NOT upload any of their chapters to online manga readers. They don't want it to be uploaded and have stopped releasing scanslations in the past if they see it anywhere.
They've currently released up to v3 ch24.
