The White Queen is the name of the boat Kyousuke Shiroyama uses as a temporary home.[1]


While it is a small boat, the cabin is larger than a student apartment and it even has a bedroom with a double bed, a simple kitchen, a bath, and a bathroom. Some people save money by buying run-down boats without an engine, but Kyousuke’s is still able to cruise. The boat has the White Queen's name on its side.[2]

Obviously, Kyousuke deeply regrets having chosen this particular name for his home, and has stated that he would have never given it that name if he’d known how hard it is to change a boat’s name once it’s been registered.[1]
