“Hey, for what reason are we born into this world?”
A rocky and energetic song completely at contrast to the vibe of the anime. This is a map to Aoi Hana (青い花 in Japanese, Blue Flower in English). The animation for the opening is also surprisingly sparse, especially for how well animated Casshern Sins is.
Anyways, if you haven’t watched Casshern Sins, I’m not sure why you’re here, but it’s an extremely well animated series that does a great job of portraying an extremely bleak world. I recommend it, but you have to know what you’re getting into, and it’s deffo not for everyone.
