For a moment I thought this was a new ship. Like a PT Boat.

Whoaaa did not expect any of the sub girls to get one at all.

Much less Maruyu, of all ships.

Unbearably cute.

They need to keep Maruyu like this all year round. This is a much better look for her.

Oh god, little cutie is actually getting some love and she looks even cuter. The christmas outfit looks fantastic compare to the usual swimsuit.

Little Maru-Claus I love it.
