The final round of Phase Three is here: a battle royal and Jinki hunt aboard MBI's cruise ship! Unfortunately, Minato has wandered into a trap-with only Ku by his side, he'll have to rely on the kindness of friends to see them through... And speaking of friends! It's a parade of familiar faces as the fighting heats up. Yukari and Shiina are on the S.S. Minaka, too-they've been searching far and wide for Shiina's long-lost sister, Ku. Will the Sekirei finally be reunited? And what will the Sahashi siblings make of it when they realize they've both been Ashikabi this whole time...? The last few Jinki are up for grabs in this thrilling fight to the finish!
