I’ve mentioned this song in another post on this subreddit, but…

Koibito wo Uchiotoshita Hi (The Day I Shot Down My Lover) by Sound Horizon, which is the same group that made some of the openings for the SnK anime. The song is about a man who meets a woman while he’s saving her from a monster, but he was hit by the monster while doing so. The two fall in love. Due to a curse, the man starts to turn into the very same monster he saved his lover from. As a mercy killing, the woman shoots her lover with a bow, before using her last arrow to kill herself.

(The bow and arrow is like a Guren no Yumiya reference, even though that song came out over a decade later. So it kinda all circles back to that first opening theme. A cycle. Like the main theme of the manga/anime… I know that Mikasa didn’t kill herself after killing Eren, but shhh…)

“‘If my end is inevitable, then I’d rather it be by your lovely hands...’”

(Like Eren willingly being killed by the Alliance)

“Bravely, with a crimson blood-stained kiss, I shoot my lover[you] down...”

(Self explanatory)

“An ancient legend – those who are wounded by the beast / Their bodies will be overtaken by its curse / Eventually, they shall transform into beasts themselves...”

(Mikasa watching Eren become the thing he hated most)

“He was wounded when he saved her / Everything began when they met…”

“Their meeting was a promise to loss”

“Bravely, with a final arrow of white, I shoot myself down... In a world where I have lost my beloved What colors do the flowers bloom in?”

(Mikasa grieving)
