OVA of Diabolik Lovers included with the upcoming game Diabolik Lovers DARK FATE.

One year ago, a UFO containing 150 aliens crash-landed off the shores of Kasai. Because no one could fix their ship, the Japanese Government decided to bestow upon them the designation "DearS" and make them into Japanese citizens, teaching them the language, customs, and culture of Japan. However, in order for them to become more familiar with human society, a home-stay program has been enacted to allow them to mingle with other humans. One misty morning, a truck carrying a capsule that housed one of these aliens ends up dropping it into the riverbank, releasing her from her confinement. She is eventually found by a high school student named Takeya Ikuhara, who saves her from being hit by a truck and takes pity on her, despite being extremely distrustful of their race and wanting nothing to do with them. Upon being named Ren, she imprints upon him as her "Master" and serves as his personal "Slave," leaving him with a "DearS" who wants to remain with him no matter what and bringing his ordinary, alien-free days to an end.

23-year-old Ryohei Yamazaki has just one thing on his mind: sex. And with his sweet-talking, honey-voiced ways, Ryohei has no trouble finding interested ladies. But none of them is just what he wants... none of them is PERFECT. Then he charms the beautiful editor of a hot magazine into hiring him. Journalism will never be the same again...

As one of the 12 Seleção that needs to save the country in order to win a game, Akira Takizawa decided to become the "King of Japan." With that in mind, after his return from the U.S.A., the remaining Seleção will also need to follow up on their own plans as they strive to outdo each other.

Saki Morimi and the other members of the "Eden of the East" are under suspicion of being terrorists, but they still do everything they can to help Takizawa reach his goal and unravel the secrets of his past, as the last fight between the Seleção begins.
