Meet Bell, a 16 years old high school student who lives in the Philippines. He always has an interest in warships as he plays games that have any relations to them. Because of his interest, he made his own warship called the "HMS Bell", a Bell-class light cruiser that specializes in supporting its fleet by anti air defense, and its fast movement. He wanted to make a ship that can support the fleet after knowing the fate of USS Arizona during World War 2. He was happy and satisfied in making his own ship that he even showed it to his friends. But what happens when he gets reincarnated in another world as the warship that he was satisfied to make?
