Hell's Tormentor Kraken

Shimizu Kuuma has known nothing but rejection in his struggle to find employment, and his prospects grow bleaker by the day. Then, without warning, life hands him a fate no job hunt could have prepared him for: he is suddenly transported to another world entirely. Before he can even grasp his new reality, he finds himself taken into the Sea Bastille—a notorious prison whose inmates are all women. Destiny shifts when Kuuma fuses with the Kraken, the fearsome monster that reigns over the sea. This union grants him tremendous power, along with a weighty responsibility: the Kraken entrusts him with the rescue of Princess Zeina. Determined to see his mission through, Kuuma embarks on a daring infiltration of the Sea Bastille. Yet what awaits within those walls is nothing he could have anticipated. The prison's female inmates are an eccentric and unpredictable lot, each brimming with quirks that promise to turn Kuuma's rescue operation into a challenge unlike anything he has ever faced.
