In "Egomama," a girl enters a strange realm where she hopes to grasp what love truly means. This search manifests as two sides of herself, each shown by a separate girl. One thinks love ought to be taken, while the other argues love must be offered freely. Instead of arguing with words, these two halves of her personality decide the winner by playing poker.

The music video for DECO*27's song Aimai Elegy, featuring Marina Nakamura on vocals, was animated by akka, mirto, and Yuma Saito. It follows a girl grappling with her anxiety about romantic relationships, feeling overwhelmed by the many potential futures ahead. Yet she is not the only one drowning in such feelings... Two versions of the song exist: the original music video premiered on December 15, 2010, with vocals by Marina Nakamura, while another version was released on December 18, 2013, featuring Miku Hatsune.
