VY2V3 Yuma and V3 Kaito - Guren no Yumiya.
These two blend together a little too well. It might be easier to hear them both through headphones.
I did all of this on Audacity. The covers here were not arranged by me.
I found the images on Bing and I do not own this song or either Vocaloid.
This song belongs to Linked Horizon and I claim no ownership. Shingeki no Kyojin/Attack on Titan belongs to Hajime Isayama and I claim no ownership.
Merry Christmas and a Happy New Year!
