It's a surprise that this show went completely unlicensed in the West, or rather, not a complete surprise, as if you would rather want Crunchyroll's heavily edited version of this show to be filled with ridiculous and copious amounts of censorship like how Winter's Shuumatsu no Harem came out to be, replicated here. It would be a horrible sight. Thankfully, the Chinese streaming company Bilibili has you covered, being the only English licensor to this glorious ecchi fest that can be fun, when you mean it with your whole heart.
Futoku no Guild a.k.a Immoral Guild sounds like what it is: a capable person in a town that has enough of doing the guarding job for his entire youth life and wants out so that he can treasure his remaining years of youth being a completely normal person. The only problem? Finding a successor that can best, or at least replicate his standards at his local guild in Mebuki City, but there's none that could fit his character. So, he is introduced to a few girls to see whether they could satisfy his requirements in retiring from the endless job, but instead they satisfy him in the perverseness of their own personalities, and monsters that don't just attack, but are unique in the way that they attack in pervy ways towards all women for the men to glimpse at their way of sight for some salivating goodness. Now that's some worry if he wants to train the girls to be just as capable as himself, both in the normal and mundane, and the sexy and sweet moments of intentionality.
Man, Kikuru Madan has it tough. He's being obviously overworked as a guard, and the unfortunate situation of spending his youth to do a job like this, certainly doesn't befit ANY growing and budding teenager of all kinds. Like any sane young adult, Kikuru wants to be free from his cage, and sure he does, but it comes at the cost of the girls that he has to constantly fight with for their idiosyncrasies: the energetic beastwoman Hitamu "Hitamuki" Kyan, the prodigy Maidena Angers, the laid-back Tokishikko Dana, the strong warrior Hanabata Nohkins, and the trap Noma Rune. No doubt that each of them has traits befitting of their character and something that Kikuru can help them develop with, but where there are strengths, there are weaknesses as well, and for all the effort that Kikuru is investing in their lives, their defining characteristics are also what sets them back from reaching their potential, say Hitamuki's clumsiness and Hanabata's over-sized boobs that are a burden weight, on top of her powers that leaves her senseless. And doggone it that the monsters use these to their advantage, forcing the girls to perform unintentional sexual acts in front of Kikuru to gawk in dismay. To add to the intended comedy, the mother-daughter family of Enome and Esyne is eccentric in their approach towards Kikuru: the young man in question having felt for the mother, while Esyne is a capable daughter that has the wish fulfillment of wanting another child from a man, such is Kikuru being a "man of fervor" enough to be a father figure. Let's face it, you watch Futoku no Guild for the characters and their character development, that on top of all of the sexual depravity, feels heartfelt.
If you have to have a studio adapting this, make sure it's one that knows the ins and outs of near-borderline ecchi, and out from the violent and somewhat weirdly satisfying sadism cringefest that is Redo of Healer, TNK is back making the absolute best that they can muster to adapt the manga...and is decent in all regards, except for all the ass-busting shots, they're on Level 69 of N I C E. Even the OST itself is just decent with Sayaka Sasaki and Minami Kuribayashi, not the best pairing but it is what it is. Although there's a nitpick if I would allow: the OP visuals are a joke for the first half, and then it suddenly going into all descriptive mode for the second half.
It's lewd, it's pervy, it's ecchi! A decent watch all things considered, and you'd land yourself a fantasy dream of an unintended harem that's willing to be of sexual servitude to yours truly. It's a lot enjoyable than it looks, though how that'll fare to each and every individual, it's on taste alone.
