Gotoubun no Seidorei

Gotoubun no Seidorei (or The Quintessential Sex Slaves) is the infamous 4-part hentai miniseries based on the hit harem anime mh:besttvshows:The Quintessential Quintuplets.

Why It Sucks

 * 1) Ichika, the quintuplets' eldest sister, was severely flanderized, as she went from a loving, caring, sometimes seductive, person into a detestable, love obsessed psycho who would do anything to keep Fuutaro only for herself. Even if it meant having her four younger sisters to be raped, molested, sexually abused, mutilated, and be taken advantage of by groups of men.
 * 2) * It feels very mean-spirited for her threatening to kick out both Miku and Nino if they don't pay rent unless if they choose to be prostitutes for a group of middle-aged guys.
 * 3) * Ichika later kills her siblings and decapitate their limbs and use the severed ones from her victims as replacement off-screen.
 * 4) The overall story revolves around rape and torture, and the writing is just straight up poor. Even if you take out the sex scenes, it still feels unsettling.
 * 5) From the exception of Fuutaro, every other male character are portrayed as unlikable rapists. Grown men and the male students that Ichika ordered to rape and gangbang the four quintuplets.
 * 6) While Fuutaro is still likable, him masturbating to videos of the four Nakano sisters getting raped that Ichika sent is a bit out of character for him. Yes, he is disgusted that he had to see it, but him masturbating to the videos isn't something he would do.
 * 7) Few continuity errors:
 * 8) * The Nakano sisters are already rich enough to pay for their own rent, so there was no reason for Ichika to threaten to kick out Nino and Miku. Unless if this was used as a plot device.
 * 9) Plenty of moments that go from shocking to downright sadistic and cruel.
 * 10) A disturbing and downer ending: After Ichika finished having sex with the defenseless Fuutaro, she reveals her newly modified body with the limbs of her deceased sisters  (Miku's and Nino's for the arms, and Yotsuba and Itsuki's for her legs) transplanted onto her. Fuutaro, left not only tied up, but also tearing up traumatized, after being told by Ichika that she and souls of her sisters will keep him happy by becoming his personal sex slave.
 * 11) While it is not on territory with Mai Chan's Daily Life nor Shin Gendai Ryoukiden of cruelty, it's still saddening to see the four sisters being molested, and have one of their limbs being hacked and stitched onto another person as their fate.

Redeeming Qualities

 * 1) The artwork can look close to the original manga at times, which looks okay.
 * 2) Fuutaro, Nino, Miku, Yotsuba, and Itsuki are still their likable selves.
