Who This Book Is For
Readers who want their harem fiction served with genuine strategic depth, corporate empire-building, and a protagonist who thinks before he acts
Who This Book Is NOT For
Anyone who cannot separate fictional slavery from real-world ethics — the premise requires you to accept a morally gray framework that some readers find impossible to stomach
Our Review
The Setup
Felix has one of the most seemingly useless superpowers imaginable — he can modify and upgrade any item he owns. In a world where people are throwing fireballs and punching through walls, tweaking the thread count on your sheets does not exactly scream “superhero.” Then a Super Villain takes over his city, and Felix discovers the black market where superpowered people are bought and sold as property. Because they are technically “owned,” his power works on them. He can enhance their abilities, increase their strength, improve their appearance — make them better in every measurable way.
From this morally radioactive premise, Felix builds Legion, a corporate empire staffed by increasingly powerful superwomen whose abilities he has optimized. He navigates slavery, cannibalism, corporate warfare, and unconventional business tactics with the cold pragmatism of a man who has found a loophole in the system and intends to exploit it until the world breaks or bends.
What Works
The premise is genuinely one of the most creative in the entire harem genre. The upgrade-anything power applied to superpowered humans creates an addictive progression loop that functions like the best base-building games. Every acquisition is a new puzzle — what abilities does this person have, how can Felix optimize them, how do they fit into his growing organization? It is the “Pokemon effect” applied to a morally complex superhero setting, and it is compulsively readable.
Felix himself is a standout protagonist. He is not a brute or a charmer — he is a tactician. Every decision is calculated, every resource is evaluated, every relationship serves the larger strategy. That does not mean he is heartless, but it does mean his version of caring looks like optimizing someone’s powers and putting them in a position to succeed rather than grand romantic gestures. For readers who prefer a competent, strategic male lead over a bumbling nice guy or an aggressive alpha, Felix delivers.
The corporate empire-building is the book’s secret weapon. Watching Legion grow from a desperate gamble into a legitimate power player provides the kind of progression satisfaction that harem fiction rarely achieves. The business tactics, resource management, and territorial expansion give the story depth beyond its harem elements.
What Doesn’t
The slavery premise is the elephant in every room. Arand treats the buying of superpowered humans with a casualness that some readers find impossible to get past. To enjoy this book, you need to accept its moral framework as fictional and not let the implications derail your reading experience. Many readers can do this — and they rave about the series. Others cannot, and they have legitimate reasons for bouncing.
Physical descriptions are sparse. Characters are hard to visualize because Arand tells you what they can do far more readily than what they look like. For a genre that thrives on vivid descriptions of its female cast, this is a notable absence. You know a character’s power set in detail but might struggle to picture her face.
The romantic connections lack emotional chemistry. Felix’s relationships with his growing roster of superpowered women feel more like employer-employee dynamics than genuine romance. The harem exists, but it is built on pragmatism rather than passion, which can feel hollow for readers who want the “fall in love” component alongside the power fantasy.
The Heat
A three. The explicit content is present but not the driving force. Arand is more interested in the empire-building than the bedroom, and the intimate scenes that do appear tend to be functional rather than passionate. This is not the book for readers searching for maximum heat or consistent spice. It is a harem book where the harem serves the plot, not the other way around.
Bottom Line
Super Sales on Super Heroes is a landmark harem series that earns its reputation through sheer creative ambition. The upgrade premise is addictive, Felix is one of the most competent protagonists in the genre, and the corporate empire-building provides depth that most harem fiction does not even attempt. If you can accept the morally gray slavery framework as a fictional conceit, this is essential reading on Kindle Unlimited. If you cannot, there is no shame in that — but you will be missing one of the genre’s most unique experiences.

The Verdict
One of the most genuinely creative premises in harem fiction. Felix's power-upgrading ability and corporate empire-building make for compulsive reading, even when the moral implications of the slavery system make you uncomfortable. A landmark series for the genre.
