In other seas, I will rule the waves

Asato Gabashvili is a police officer of half-Japanese and half-Lebanese descent who works at the Stoanian Maritime Police Force, a law enforcement agency in the Republic of Stoania which is underequipped, underfunded, and with poor morale due to its failure in combating piracy off the nation's coast.

One day, while en route with patrol boat P22 to join the Seychelles Coast Guard in a joint anti-piracy operation, he falls asleep on the wheel due staying awake for 24 hours because of a false alarm situation that had occured a day earlier.

After waking up, Asato discovers that he has been transported, along with his patrol boat, in an unfamilliar world where most of the terrain has been taken over by the seas and nations exist as small islands scattered around the globe. At the same time, Asato manages to acquire a new skill that allows him to purchase and summon warships from three different eras. From 19th century dreadnoughts and ironclads to modern 21st century firgates and corvettes.

Unsure of what to think of his current situation, Lieutenant Asato decides to explore this new world of magic, knights, sea monsters, and pirates, while still trying to do his job in enforcing maritime law with the help of Lady Adeliz, a vigilante pirate who is fighting to free the seas from the sea monsters and the corrupt king that have been terrorizing her nation and her people.

Using this new skill of his, Asato begins to explore the seas with his new ally, fighting off the various threats, sea bandits, and creatures, earning him the title of hero by the locals and governor, much to his dismay and annoyance....
