Blood-C: The Last Dark

In Tokyo six months after the events of Blood-C, Saya pursues Fumito Nanahara, the human guardian of Shrovetide who manipulated and betrayed her. With the help of an underground organization called SIRRUT, led by Fumito's relative Kuroto Mogari, Saya infiltrates a private academy to gather information on Fumito's whereabouts. As she delves deeper into Tower's main base, Saya fights off Elder Bairn hybrids and confronts Fumito, who reveals his intent to dissolve Shrovetide using her blood as the ratio of humans to Elder Bairns has shifted drastically.
