I recommend watching this MV at least once to understand where I'm coming from. From a music standpoint, it does alright, and Yoasobi's catchy vocals complement the visuals nicely. The main appealing part of this MV to me was the omage to series it is referencing with original mural-like renders alongside some amazing 3D CG works. I only say it's a 7/10 because it's not one of those songs you can loop, as you can get tired of the tunes fast. The score is carried by the art and animation alongside the VFXs. The MV tells the unseen story of Freiren and her time whenshe was traveling with Himmel's party to slay the Demon king 80 years ago while getting flashes about the present, seeing how lonely she is long after her friends, she regrets not getting to know deeply have passed. If it's comparable to anything this season, it's like Jujutsu Kaisen's Season 2 opening, "Where Our Blue Is" by Tatsuya Kitani, where the animated intro shows a similar story of a character's unseen yet nostalgic and distant past where they were happier. That's what this Yoasobi song and MV feel like to me, hitting similar narrative beats.
