Kisara was pierced by a spear in front of Shu in the middle of the battle against the demons that were the cause of all the attacks on an artificial island. Helped by Ayano and Sharon, Shu evacuated from the spot helplessly, but what she saw was her younger sister, Kanna, whom she was looking for. After that, the desperate resistance of mankind, which gathered all the power of Veyron City, was in vain, and the large-scale disasters caused by Kanna, who was certified as an S-class demon, expanded the range of damage one after another. Shu, unable to do anything, just stares at Kisara, who has collapsed and has completely lost consciousness, let alone biological reactions. As if to respond to his heart, Kisara gently wakes up.
