After trumpets of the apocalypse proclaim the fall of humanity, vampires arise from the shadows to rule the earth. Yuichiro wants just one thing-to get revenge by killing each and every vampire.

On the way to Guren's safehouse to finally get the details on his true plan, Yuichiro drops a bombshell of a question on him: "Did you kill my family?" Guren hesitates to answer, and Yuichiro, wanting a clear response no matter what, challenges him to a fight. As the two battle, Guren comes to realize Yuichiro's growth, while Yuichiro is reminded of Guren's strength.
