淫行客船渦潮 -奈落のクルーズ-（Inkou Kyakusen Uzushio -Naraku no Cruise-）

---From Japan to the world's ports. A Luxurious Panorama Park on the Sea!

Enjoy a quality cruise at an affordable price! Skull's Sea Line (SSL) is a newly established Japanese cruise company that merged with a major overseas cruise line. The luxury cruise ship Uzushio has restaurants, bars, lounges, swimming pools, fitness clubs, spas, beauty salons, stores, theaters, casinos, medical offices, and other general facilities, The Uzushio is a luxury cruise ship owned by SSL, and is equipped with state-of-the-art technology, including restaurants, bars, lounges, swimming pools, fitness clubs, spas, beauty shops, theaters, casinos, and medical offices, and even has a diving service.

Although basically a Japanese ship, the concept is “a ship that transcends categories". The ship is designed to attract a wide range of passengers with the facilities of a casual cruise ship, the attentive service of a premium luxury cruise ship, and a well-trained language staff. The concept is attracting attention with its catchphrase, “The best luxury cruise ship of the century” and, with regular giveaways, tickets for a cruise may be within reach of the average person. The Uzushio is on its maiden voyage with a big campaign.

But this is just the beginning of hell. The most luxurious cruise ship of the century is about to set sail like a whirlpool, drawing in its prey as its name suggests.
