恋爱幕末男友外传～在时空的彼方盛开之恋～CRISIS

One day, a black ship fell from the sky... The "Susanoo Incident," which unfolded in the capital of Kyoto over the legendary treasure "Jishingi" possessing the "power to traverse time," concluded with the death of the masked shogun "Mugensai," also known as Yoshida Shoin. "There are still things we must do." After paying respects at the grave of their former teacher, Shoin, in their hometown of Hagi, Takasugi Shinsaku and his partner Katsura Kogorou returned once more to the capital of Kyoto. Beside Takasugi, who runs forward to uphold his teacher's teachings, stands Katsura, his gaze unusually distant... At that moment, with the roar of cannon fire, the sky split open, and from a "tear in spacetime," the Jishingi—which should have been destroyed—appeared. The Jishingi, having begun to possess a "will," started to run out of control uncontrollably!! Furthermore, standing in their way as fated rivals is the Shinsengumi, who lost their vice-commander Hijikata Toshizou in the previous battle!! And what Commander Kondou Isami spoke of was nothing less than the existence of a new "Mugensai"— Will they restore it, or change it? Takasugi: "I will definitely restore the flow of time to its rightful course." Katsura: "There's something I've never been able to tell you all this time." Tossed about by an un-resettable crisis, the new story of these patriots begins to unfold!!
