Kantai Collection: KanColle Zoku-hen  

艦隊これくしょん -艦これ- 続編

As the sun rises over Leyte Gulf, tensions are high as the mysterious Abyssal Fleet prepares for a crucial confrontation with the Kanmusu-young girls imbued with the spirits of warships. With Shigure leading the charge as part of the First Striking Force, Third Section-or 1YB3H-the Kanmusu must steel themselves for what could be their final mission together. Despite being outnumbered by their formidable foes, Shigure and her crew refuse to give up without a fight. As they sail toward the heart of the conflict, they must rely on each other for strength and determination to prove their worth as skilled vessels.

To improve the series' quality, KanColle: Itsuka Ano Umi de was shortened to eight episodes instead of 12.
