Blood-C: The Last Dark

Saya and Fumito's deadly wager ends in a brutal massacre that leaves only Fumito, Yūka Amino, and Saya alive. The revelation that Saya is bound by an oath against drinking human blood intensifies the betrayal and sparks her vow of vengeance. The event cements the grim stakes of the conflict moving forward.

Six months pass and Tokyo endures under Fumito's growing control. Signs of his power are seen in tighter surveillance and the looming threat of further crackdowns on youth. The city teeters on the edge of open conflict as the balance of power shifts.

Saya rescues Mana Hīragi from a rampaging Elder Bairn, drawing Mana deeper into the struggle. Mana's rescue marks the start of her involvement with SIRRUT and the resistance against Fumito's regime. This moment ties Mana's fate to Saya and the wider battle to control Tower.

Mana's rescue pulls her into SIRRUT, a covert resistance led by Kuroto Mogari. Kuroto offers his aid to Saya in exchange for her cooperation, linking Mana's personal history to the larger power struggle. The alliance begins to reshape who can challenge Tower's grip on Tokyo.

Mana's hacking skills become essential as recovered memories and technical prowess locate Tower's main base. Saya's infiltration into a building controlled by Fumito demonstrates the new alliance in action. The mission sets the stage for a decisive confrontation.

Saya faces Tower's security chief Kutō, who uses Saya's own blood to morph into an Elder Bairn hybrid. The transformation demonstrates the brutal risks of the mission and the enemy's willingness to push biology to its limit. The threat tests Saya's resolve as she presses forward.

Inside the base's basement, Saya confronts Fumito and encounters Kuroto again. Kuroto drugs Saya with a mysterious substance, and the conspiracy between Fumito and Kuroto is laid bare, including their targeting of each other's families. The truth tightens the noose around the power players.

Revelations reveal that the Elder Bairn who attacked Mana was her own father, reframing Mana's history and motives. This shocking truth deepens Mana's personal stake in the battle and tests her trust in those around her. The personal becomes inextricably linked to the political struggle.

Kuroto is stabbed with Saya's blood by Fumito, transforming into an Elder Bairn seed and sealing his fate. Fumito's plan to dissolve Shrovetide is revealed as he consolidates power over the network and aims to end the balance that sustains both sides. The scheme shifts the stakes of the entire conflict.

Fumito fuses with the seed to become a colossal Elder Bairn and threatens to erase humanity's balance. Saya must defeat this towering threat, a climactic battle that tests every edge of her oath and power. The fight determines the fate of Tokyo and the city’s uneasy peace.

Fumito confesses his motives—to control the balance and to draw closer to Saya—and then dies by impaling himself on Saya's sword. The admission reveals a personal obsession behind the political machinations. With his death, the direct threat to the balance begins to waver.

The city steadies, and Saya vanishes into the shadowed streets, leaving Tokyo to a fragile calm. Yūka Amino ascends to governorship and repeals the Youth Ordinance Bill, easing restrictions that once controlled youth online and in public life. SIRRUT disbands and returns to ordinary life as the city breathes, albeit warily.

Mana begins a quiet search for Saya, holding onto the memory of their dangerous journey. A fleeting glimpse of Saya appears again on Tokyo's streets, a reminder that their fates remain intertwined even as the city tries to move forward. The future remains uncertain, but a thread of connection endures.
