I watched this back in January. It's still one of the best Frieren/Zoltraak AMV's on RU-vid. I was hoping you'd do a version 2 with the second half of episodes of Frieren.
I'm not Japanese, but I cried when I heard this song and found out the translation... It resonates in you with the pain of those people who will no longer be able to see their loved ones...
Zoltraak, Magia ofensiva criada para matar humanos, mas modificada para extermina demônios. Parece ironia, não so o criador foi morto pela própria magia, como a sua raça esta quase extinta por conta dela.
