Long Summary
In continuation from the previous chapter, Kimizuki, Shinoa, Mitsuba, and Yoichi head towards the location of Mikaela and Yūichirō. After approaching a sharp turn, Shinoa boasts of the power that the First Vampire left inside of her. As they approach the turn, Shinoa uses her scythe to grab hold of the building and flies out of the vehicle. Mitsuba tries grabbing her and Yoichi tries grabbing Mitsuba but both fly out of the vehicle as well. Yoichi tries to grab Kimizuki but ends up grabbing his glasses instead. Kimizuki then puts his foot through the steering wheel to grab onto Yoichi's leg and pull all of them into the vehicle.

Meanwhile, Yūichirō is cradling the top half of Mikaela's severed body, when Mikaela starts screaming in pain. Yuichiro begins to cry and begs God and the Devil to save Mikaela, even if it means killing him.

Mika's body begins to float in the air, dark electricity-like power surging from his body.

Yu is then transported to his subconscious with Asuramaru where the demon tries to convince Yu that saving Mikaela is a lost cause. Yu tells Asuramaru to shut up and threatens to kill him if he doesn't stop talking. Asuramaru responds by saying that it's a demon's job to grant a person's deepest desires. He continues to say that Yu can say whatever he likes and Asuramaru would do it if it meant healing what was hurting Yu.

Yu cries out that he doesn't want to be alone, not after what he had already experienced when his family was killed the first time. He continues and says that he wishes to disappear forever and releases the thoughts that have been plaguing him, calling himself "a stupid monster that can't save anyone" and verbalizing his wish to die. If Asuramaru would be happy controlling his body when he died, he'd be glad he was of use to someone. Yu apologizes to Asuramaru for being so weak.

Asuramaru tells him that strong humans don't exist and that it wasn't his fault. He tells Yu that if he wants to die, it's his choice to make but to keep in mind Mika's words before he had been hit. ("Don't worry Yu, I'll keep you safe.") Asuramaru then encourages Yu to live, because Mika had loved and given his life for him, that Mika had given him a reason to live as he died. Yu begins to scream and Asuramaru asks Yu if it hurt and explains to him that the reason why humans have greed is because it helps them find a reason to cling to life. The demon tells Yu to watch Mika die so it gives him a reason to live.

Mikaela is shown once again with the dark electricity around him and tells Yu not to cry. Yu screams out that he doesn't want Mika to leave him because he doesn't want to be alone. Mikaela believes that Yu will be fine, tearfully uttering his last words, that he loves Yu before exploding.
