Peaceful Diary of High School Fleet

Ongoing

はいふり

In a Japan that has developed as a maritime nation, specialized all-girls schools train students to become "Blue Mermaids"—elite women who protect and live by the sea. The story follows a group of girls enrolled in such a school, where they learn both classroom theory and practical skills to navigate and safeguard the ocean.

As they strive to excel in their studies and adopt an international mindset, the students face the challenges of their rigorous training. But when a routine exercise takes an unexpected turn, they must rely on their wits and teamwork to overcome a crisis that tests their resolve to become true guardians of the sea.
