The Back Garden of the Mermaid Emperor

After traveling through time, Ishikawa was either on his way to fishing or selling fish, leading a boring life until one day he discovered that he could actually turn into a mermaid and swim in the ocean. So… After turning into a fish, he discovered that blowing bubbles turned out to be a talent. He drank sea water until he vomited, had nothing to do, subdued tens of thousands of sharks to serve as his little brothers, and the women in his arms were all the most beautiful mermaid princesses in the four seas. He conquered the ocean with an army of thousands of sharks. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
