By his side, the attractive Keiko, the reincarnation of the woman he had been in love with for centuries. But after Keiko is kidnapped by a commando formed by his ex-enemies, Kenshin goes to Harlan for help. To rescue Keiko, they will have to land on a remote island in the middle of the Ocean and face General Tamasaburo’s legion of diehard fighters. And, alas!, these are not common human soldiers, but invulnerable Han’a demons!
