The evidence gathered points to the real Demon Agent. And it was Shu's most trusted person. As the Police Agency and top officials of AAA continue to strategize and negotiate, Shu confronts the true criminal alone. Why? For what reason? All words and all questions are in vain when the real criminal transforms into a vicious demon right before his eyes. Its power is so overwhelming that, even with AAA's fighting strength concentrated, there is no damage. At this rate, all the people Shu cares for will be hurt. With raging anger and profound sadness in his heart, Shu decides to offer all his precious memories to Kisara. All for the sake of defeating the demon.
If that was all, you could say
he was simply a brilliant officer.

Wenn das alles ist, könnte man ihn auch
als herausragenden Wachtmeister betrachten.
Ça peut simplement signifier
qu’il est compétent.
Se è tutto qui quello che avete,

meramente um policial competente.
Может, он просто 
предан делу, что такого?
