Out of all the CSM OPs and EDs, ending 05 really stood out in terms of aesthetics and depth. The animation mainly incorporated most famous art movements and styles jumping on different periods-- from medieval to modern. You can notice classicism, neo, renaissance art, Pieta, expressionism, kafkaesque, Centaur symbolisms, still life, cubism, surrealism, Penrose stairs, dadaism, optical and psychedelic art, futurism, conceptual art, and more avant garde art forms and allegories depicted in every scene, even on its transitions! There's too much going on in every second and tons of details to grasp in just one sitting. With all its references and foreshadowing elements (Four Horsemen, gun barrel sequence, infinity symbols= staircase, Eternity Devil arc, etc. ) You have to replay it couple more times to grasp something deeper. It is an absolute tease for both watchers and manga readers. Really one of the most aesthetic and esoteric EDs I've seen in anime. You know the artists and the team invested much creative juice and effort on this one 💣 Kudos. (edited)
