Downfall

Downfall (滅亡) is the sixth song that is featured in the film Kaiju of Retribution Tatsura. It is performed by Osamu Takai, the singing voice of Yukimura Katsuki.

Usage
The mysterious cloaked man walked into a dark alleyway somewhere in Tokyo, where he sees Yukikaze's pendant that was discarded from Yomihara up into the surface, amidst the garbage scattered on the ground. He takes off his hood, revealing to be Yukimura Katsuki, and picks up the pendant. Yukimura sings his hymn of regret that he is unable to act for fifteen years after he faked his death in his battle against Nobunaga Oda and left his lover Shiranui Mizuki alone to raise their child, and unable to take back those fifteen years. By the end of the movie, he leaps into the air and transforms into his kaiju form, the samurai dragon Amatsu.
