Original Release: September 6, 2012 – May 31, 2013
Number of Episodes: 2
The episode begins with the Gremory team chasing a stray devil, successfully capturing him, and sending him back to the underworld where he awaits his punishment. The next day, Issei complains about the stray devil’s words and recalls the devil’s lab he entered with Rias and Akeno. Then Issei learns from Matsuda and Motohama that many of the schoolgirls, the ones with the big breasts, are coming down with anemia one by one.
Back at the Occult Research Club, Issei and the others learn from Grayfia that the Stray Devil they caught used to do research on monsters, specifically the Chimera. Yuuto and Koneko then return to the club room after finding the location of the monster that made the girls sick. Later that night, Rias and her team head to the monster’s location and find out that it is a plant dragon chimera. Before they can take care of it, two female students, under some kind of hypnosis, enter the scene.
The chimera attaches tendrils with flowering orifices to the students’ breasts and sucks out their life energy. After Rias determines that the chimera never sucks its victims to death, the group begins a battle to destroy it. However, due to the Chimera’s superior regenerative abilities, Rias, Asia, Akeno, and Koneko are overpowered and eventually fall into the Chimera’s captivity, which coats the girls with a corrosive slime that dissolves their clothing to more easily access their breasts.
After a while, the Chimera suddenly releases Asia and Koneko and focuses its attack on Rias and Akenos, presumably due to their larger breasts and thus larger reserves of life energy that it siphons from them. When Grayfia appears through a magical communication circle, she informs the group that the Chimera has the ability to suck the energy out of large- breasted girls and bear fruit that will allow each girl to enlarge her breasts to her heart’s content after eating them.
Angered by the sudden information, Koneko pounces on the Breast Chimera, while Kiba manages to free Rias and Akeno from the Chimera’s grip. Rias orders Issei to transfer his enhanced power to her, which he does in tears, allowing her to destroy the Chimera with her destructive power. OVA ends with Issei being buried underground for a night by his friends as punishment for trying to defend the Chimera.

Later, on the way home after Issei has signed a contract with his new client, Issei and his friends are given an assignment to hunt down a Stray Devil in an abandoned factory.
The team manages to defeat the Stray Devil, although Kiba was extremely distracted. Kiba reveals to Issei that he is seeking revenge against the holy sword Excalibur. Later at his house, Issei finds out that Kiba was once part of a project called “The Holy Sword Project” and is only a survivor.
On the way back, Kiba witnesses a priest being killed by Freed and becomes even more enraged by the Excalibur Freed is wielding, leading to a fight between the two.

Then, Rias receives a message from Yuuto, who informs them that Gasper has found the source of magic. When they arrive at the source of magic, the Occult Research Club and Irina decide to split into two groups, leaving Akeno and Asia behind.
The advanced group then meets the person responsible for the monsters as he reveals his past and Issei stands in awe of him. Suddenly, Azazel appears and reveals that the priest who stole the women’s underwear is the man closest to the Philosopher’s Stone. The priest prepares to cast another spell, but stops halfway because he is not perverted enough when Koneko reveals Gasper’s panties and the spell goes wrong because the priest becomes an underwear monster.
The underwear monster begins to take advantage by stripping the girls and manipulating their bras. After the girls surround Issei, the underwear monster, now jealous, decides to absorb the girls. After Issei realises that the priest was wrong, he begins a sermon about breasts, which the underwear monster doubts.
