It's uncertain whether it was because the crabs couldn't match the mermaids' speed underwater, or perhaps the mermaids became more ferocious in the water than they were on land, but after the mermaids retreated, the Samurai Crabs did not pursue them into the sea.

Kanihime, in her bright red crab armor paired with a white Feather Weave and with a crab shell-shaped Star Helmet on her head, only revealed a small, delicate, and fair face, with some soft yellow locks hanging beside her temples, making her look like a little can that could move.
But there's no denying she did carry a bit of the majestic aura of a grand ocean general.
