This special is a compilation video of the whole season in which each girl has a her own individual song sung by her respective voice actress. It highlights her story and there is a karaoke text frame on the bottom for the watcher to sing-a-long.

The story begins in the future when Earth itself is no longer inhabitable by living creatures. Humans began their interstellar migration with space colonies. Vince and Hana work as researchers in the Cambrian Project. Together with the creature Pikaia, they seek the Lost Code, the key to restoring Earth, and aim to return to Cambrian-era Earth.

After falling in battle, the samurai Jin wishes to be reincarnated with an "invincible metal body"; thus he is reborn as a coffee vending machine in present-day Seoul. Each night, he continues his eternal battle with other samurai who have been reincarnated as otherwise mundane objects. But, one day, he meets Hemi, a girl who buys a drink from Jin's vending machine body. After many similar encounters, Jin realizes he has fallen in love with her. Will his love be able to reach Hemi?

It's a "pop" and cute everyday anime based on the 4-koma manga featuring the characters from Uma Musume: Pretty Derby.
