Dear High School Fleet fans, A-1 Pictures, Production IMS alumni, and anime lovers worldwide,

"High School Fleet" (Haifuri) is a thrilling and heartwarming anime that follows the crew of the destroyer Harekaze at Yokosuka Girls' Marine High School. In a world where much of Japan is submerged, young women train as "Blue Mermaids" to protect the seas. The series perfectly blends naval action, military hardware, friendship, comedy, and emotional character growth.

The original 12-episode TV series (2016) by Production IMS, the two OVAs, and the 2020 movie produced by A-1 Pictures gave us unforgettable moments with Captain Akeno Misaki, Mashiro Munetani, the entire Harekaze crew, and epic sea battles. However, the story and the rich universe have so much more potential left — the ongoing manga continues to expand this world with new adventures, rival schools, and challenges at sea.

With this petition we call on:

A-1 Pictures and other capable studios to produce High School Fleet Season 2
All producers, license holders (including Aniplex), and partners to support a full continuation of the series
The anime industry to give this fun, unique, and beloved naval academy title the sequel it deserves
If you love the strong female crew, the detailed ship animations, the mix of slice-of-life school life with high-seas action, and the bond between the Harekaze girls, please sign now and share this petition!

Every signature counts. Let’s set sail once again and keep the Blue Mermaids’ journey alive! ⚓🚢

Thank you for your support! #HighSchoolFleet #Haifuri #Season2 #BlueMermaids
