In Vandread, men are from Mars and women are from Venus! Well, not quite. Technology has allowed mankind to colonize the entire Milky Way galaxy, and in one star system, the men and women live on two different planets, Taraak and Mejere. A bitter and very literal gender war rages, to the point where they don't even see each other as the sames species anymore! Hibiki Tokai, a male third-class laborer from Taraak, ends up stuck on a battleship after a botched attempt at stealing a robot. When female pirates capture the Taraakian Vanguard, things don't look like they could get any worse for Hibiki. Unfortunately, they do; when the male crew of the Vanguard fire on their captured vessel out of desperation, they created a giant wormhole, which sucks the Vanguard and the Mejeran pirate's ships into itself! Now, stuck far away from their home planets, these men and women must learn to work together if they ever wish to make it back home.

The anime's story will start where the third season left off, at the competition for who will open the Triple S international sporting event. Raging Entertainment's HE★VENS idol group had hijacked the competition between QUARTET NIGHT and ST☆RISH, causing chaos. However, after the QUARTET NIGHT members suggest a certain idea, the three groups aim toward a new stage, with HE★VENS swearing to get their revenge on the other two groups.

Serious and generous, but a bit shy, Yuudai has been unsuccessful with the opposite gender. Chizuru is an energetic and cheerful girl, but when it comes to boyfriends, she's been unlucky and clumsy, and never had a steady relationship. This is the first Christmas the couple spends together. Chizuru loves animals and Yuudai plans to give her a rabbit in a box, but it turns out to be... a mini donkey?! As the funny creature escapes, Chizuru goes after it, and Yuudai loses sight of them both! The time that should have been spent together... The important feeling that should have been revealed... Small, but precious things that tend to be buried in every day life. What answer will the two youngsters find while separated from each other? Yuudai and Chizuru—their feelings and the time they spent far from each other are delicately unfolded in this double-sided pure love story told from two different perspectives!
