Synopsis
Shinoa resists Shikama Dōji opening "the door" and silences him before aiding her squad against the Horsemen.

Meanwhile, Yu and Kimizuki are able to inject the drug into the 6th Trumpet and stabilize it.

Summary
Shinoa shuts the door to her emotions. Shikama Doji says Shinoa will be unable to control her desires, and she will be overcome by lust and become obsessed with Yuichiro. Shinoa restrains him and tells him to shut up.

Returning her attention to the battlefield, she asks if the only reason Yu needs to live is the desire to save his family. She says this is fascinating. Shikama Doji watches over her. She wants Yu to teach her more about reasons to live.

Mika and the humans charge and attack the Horsemen.

The sixth trumpet keeps telling Yu to die, but Yu says they don't need to fight. He says they are both part of the same experiment. Yu eventually jumps on top of the angel and holds him down. When he tries to attack Yu with the trumpet, Mika deflects it. Then, Kimizuki appears with the injection and stabs it into the angel's neck.

The sixth trumpet floats into the air, and a cross-shaped object with a ring on the top three points shoots out of his chest. The sixth trumpet falls, and his wings dissolve. Yu and Kimizuki catch him.

Then, there is a reaction from the Horsemen.
