#1: Oppai, Minorimasu! (Episode 13) A rumor is going about the school about how girls are disappearing and coming back ill and with their breast size decreased. #2: Oppai, Motomemasu! (Episode 14) While observing how the others do their jobs so they can do theirs better, Issei and Asia go with Rias to see if a coffin is cursed. During the investigation Issei is possessed by an Egyptian magician named Unas, It just so happens that Unas is just as perverted as Issei. Unas will only leave Issei's ...
When cursed coffins and ancient perverts collide, the devil squad must save more than just their reputations.
In these two extra episodes, the supernatural academy finds itself tangled in a bizarre, breast‑centric mystery. Rumors swirl that female students are vanishing only to return pale, weakened, and mysteriously shrunken—prompting a frantic investigation by Rias Gremory’s devilish squad. Their sleuthing leads them to a cursed coffin that seems to be the epicenter of the phenomenon, and the team must confront a lingering curse that threatens to strip more than just confidence from the girls. Meanwhile, Issei Hyoudou and the shy but determined Asia Argento tag along, hoping to learn the ropes of devilish combat. Their curiosity lands them in an unexpected possession: the ancient Egyptian magician Unas hijacks Issei’s body, bringing his own lecherous agenda into the mix. Unas, bound by a centuries‑old devil’s curse, can only be freed if the curse is broken—forcing Issei and his allies into a chaotic blend of exorcism, slap‑stick fanservice, and reluctant teamwork. The episodes balance over‑the‑top ecchi humor with the series’ trademark action and supernatural lore, delivering a wild, self‑aware romp that both satiates and satirizes the franchise’s most infamous tropes.
