Four minutes and it sits on your chest for the rest of the night. This is DECO*27 in his early vein, Marina Nakamura's vocal carrying a girl who is terrified of the relationship in front of her and drowning in every future she can imagine, and the animation from akka, mirto and Yuma Saito refuses to rescue her. The reveal that she isn't the only one going under is the whole song, and it lands without a word of dialogue. There is no spectacle here, no set piece, just a mood held steady until it breaks. Worth knowing the 2010 original with Nakamura and the 2013 Hatsune Miku upload hit differently, and fans still argue over which voice makes the ending hurt more. Pick one, then go listen to the other and see if you were right.

A girl is held back by her fear of being in a relationship. The many ways the future could turn out press in on her until she feels as if she is drowning in them. But she is not the only one going under. This psychological music video accompanies the song Aimai Elegy by DECO*27, with animation by akka, mirto and Yuma Saito. The original video, released in December 2010, features vocals by Marina Nakamura, and a later version from December 2013 is sung by Miku Hatsune.
