Introduction
マル戦計画で生まれた丁型海防艦、その二番艦第四号海防艦でっすー。そうね~ぇ、よつ……って呼んでくれていいよぉ? ていとく、よろしくねぇ! I'm the 2nd ship of the Type-D coastal defense ships that were created under the Maru-Sen Plan, Kaiboukan No.4. Yeah, you can call me "Yotsu" instead. Admiral, happy to work with you. The Maru-Sen Plan was a planned expansion to the navy started in April 1943.
