Shuu, Kisara, Ayano, Akino, and a suit whose name escapes me meet with Sharon at the safe house where she’s wining and dining herself to go over the present situation. Essentially, Asmodeus is a demon that has existed in the human world for a good long time in various forms, and Miles’ memories confirm the Hive Three Mine incident was Asmodeus’ doing, not Shuu’s dad.
The various Demon Hazards around the city form the same shaped magical circle that circled Europe, and the location of the final ritual is far offshore to the northwest. Official maps say it’s just open ocean, but it’s likely not.
While Kisara and Sharon go on a boat trip to find the island where they believe Hive Three Mine and Kanna (Asmodeus’ gate to this world) to be located, Ayano takes a ride with Hachisuka Linfa to ask her about the secret location. Mikhail sends another group to stop and arrest both Ayano and Akino, but Shuu ruins his plans by borrowing an attack helicopter.
Linfa, proving she’s still a friend to Ayano, gives her the coordinates to the mine site, now shifted since Bayron City itself was moved away from said site 12 years ago. They arrive just as Kisara and Sharon locate Kanna, whom Kisara has to keep Sharon from killing on the spot.
Mikhail then decides to try out an old “Star Wars”-style satellite weapon to destroy the entire site before Asmodeus can pass through the gate, but he’s a bit too late. The weapon is ineffective, and Asmodeus’ colossal hand emerges from the island, and the wound to its palm quickly closes.
Kisara managed to escape the initial explosion along with Sharon, and while they try to fight the hand of Asmodeus (from which hundreds of other arms and hands branch off) Asmodeus summons of all its previous forms, only in stone, including that of Shuu and Kanna’s mother.
Shuu arrives at the scene and asks Kisara to take all of his remaining memories, if that’s what’s needed to get rid of Asmodeus. Kisara bursts into tears and hesitates, fearing Shuu won’t be Shuu anymore if she obeys him. Then she’s impaled through the chest from behind…by Kanna, or at least the Kanna who is serving as Asmodeus’ gate.
Assuming Shuu remembers his sister’s face (and we’ve seen he’s in such a bad way he barely remembers Ayano’s name), this has to be a major mind trip for Shuu, who will now almost certainly have to give up way more than he should to heal and power up Kisara. If Asmodeus succeeds, Bayron City and perhaps the world may be doomed. But stopping Asmodeus may mean killing Kanna. Not an enviable choice.
