Im halfway through the anime and i just needed to say something about the opening.
ive never seen an anime opening that captured the feeling of the actual show quite as much as this one. like, it starts out creepy and disturbing, but then it brings in bittersweet nostalgia and human heartbreak and longing, and it blends these feelings into this nauseous, but somehow comforting, weight deep in your chest. its so beautiful, its the type to really stick with you.
most others ive seen are pretty generic, especially if you dont translate the lyrics. high energy, sweet, sad, angry, etc. but this one i dont even need to translate the lyrics to feel what it's saying.
