The Complete Review of the Black Souls Series: Madness, Fairytales, and Dark Fantasy

What happens when you take the punishing difficulty, cryptic storytelling, and grim atmosphere of FromSoftware’s Dark Souls and Bloodborne, merge it with twisted versions of classic fairy tales, and wrap it all in a highly explicit, Lovecraftian RPG Maker game? You get the Black Souls series.

Developed by indie creator Sushi Yuusha (Sushi Hero), this duology has achieved legendary cult status within the adult gaming community. To call it “just an 18+ RPG Maker game” is a massive disservice. Beneath its pixel-art exterior lies one of the most profoundly tragic, lore-heavy, and emotionally devastating narratives in the entire eroge medium.

You play as an amnesiac protagonist known as Grimm, thrown into a dying, rotting world with one single, burning directive: Find Alice. Along the way, you will encounter iconic fairytale heroines like Little Red Riding Hood, Cinderella, and Jeanne d’Arc—but their stories are far from happy. They are corrupted, traumatized, and driven mad by the world around them.

If you are a fan of deep lore-crafting, challenging turn-based RPG mechanics, and dark, psychological horror mixed with adult content, the Black Souls series is an absolute masterpiece. Let’s dive into the core features of this grim universe and explore why it commands such immense respect.

Core Features of the Black Souls Universe

Do not let the standard RPG Maker engine fool you. Sushi Yuusha pushes the boundaries of the software to create a deeply immersive and terrifying experience. Here is what defines the franchise:

The “Souls-like” Influence & Deep Lore

The inspiration from Dark Souls is worn proudly on its sleeve. The narrative is not spoon-fed to you. Instead, you must piece together the tragic history of the world by reading item descriptions, talking to cryptic NPCs, and paying attention to environmental storytelling. The world is interconnected, filled with hidden shortcuts, deadly traps, and brutal boss fights that require genuine strategy and preparation to overcome.

Twisted Fairytales & Lovecraftian Cosmic Horror

The world is a bizarre, horrific amalgamation of Alice in Wonderland, classic Grimm’s Fairy Tales, and the Cthulhu Mythos. The heroines you meet are broken variations of their storybook counterparts. As the series progresses, the traditional dark fantasy elements slowly give way to mind-bending, cosmic horror, where outer gods manipulate reality and sanity is a luxury you cannot afford.

The “SEN” (Sanity) Mechanic

This is the most crucial gameplay mechanic in the series. Your “SEN” dictates your grip on reality. High SEN means you see the world clearly, but low SEN causes terrifying hallucinations, alters NPC dialogue, changes the enemies you encounter, and directly dictates which of the game’s multiple endings you will receive. Managing your madness is just as important as managing your HP.

Grim, Tragic Adult Content

Be warned: the adult content in the Black Souls series is incredibly dark. While there are consensual, affectionate scenes, much of the 18+ content involves themes of violation, madness, and corruption (often tied to the game’s “Pledge” system). However, the erotica is never just “thrown in” for cheap thrills. It is deeply woven into the tragedy of the characters, emphasizing the cruelty of the world and the despair of the heroines.

The Descent into Madness: Game-by-Game Breakdown

The series consists of two massive mainline titles. While they share a universe, the leap in quality and ambition between the two is staggering.

Black Souls 1 (2017)

The first game sets the foundation for the nightmare. You awaken in a mysterious asylum and must journey across a decaying continent to find Alice.

Black Souls 1 is heavily inspired by the original Dark Souls. You will traverse dark forests, rotting castles, and poisoned swamps. You have the choice to help the fairytale heroines you meet or kill them for their unique souls and equipment. The combat is traditional turn-based, but bosses hit incredibly hard. While it is a fantastic game in its own right, its primary purpose is setting up the lore, the cruelty of the world, and the tragic cycle that the protagonist is trapped in.

Black Souls 2 (2019)

If the first game was Dark Souls, Black Souls 2 is Bloodborne—and it is widely considered one of the greatest RPG Maker games ever created, adult or otherwise.

The protagonist awakens in the Victorian-inspired city of Lordran, dealing with a mysterious “Beast Plague.” The scope of Black Souls 2 is massive. The storytelling is significantly improved, featuring mind-blowing plot twists, deeper character development for the heroines (especially the enigmatic Red Riding Hood and Mary Sutherland), and an incredibly complex, interconnected map. The Sen (Sanity) system is pushed to its absolute limits here, creating a psychological horror experience that will genuinely leave you questioning reality. It is a heartbreaking, haunting masterpiece.

Overall Review & Summary

The Black Souls series is not for everyone. It is punishing, deeply depressing, and requires a high tolerance for dark themes and cosmic horror. But for those willing to brave the abyss, it offers a narrative experience that rivals mainstream AAA titles.

Feature	The Good	The Bad
Story & Lore	God-tier world-building, incredible plot twists, and an emotionally devastating narrative.	The cryptic storytelling means you might need a wiki to fully understand the lore.
Gameplay	Rewarding exploration, deep secrets, and a brilliant implementation of the Sanity (SEN) system.	As an RPG Maker game, the turn-based combat can sometimes feel visually static or clunky.
Atmosphere & Audio	Masterful use of public domain classical music and chilling sound design to create an atmosphere of dread.	The pixel art is functional, but lacks the high-budget gloss of modern visual novels.
Adult Content	Story-driven, highly impactful H-scenes that enhance the grimdark tone of the universe.	Contains extreme dark fantasy tropes (non-con, guro, mental break) that require trigger warnings.

General Community Feedback

Within the hardcore eroge and visual novel communities, the Black Souls series is treated with almost religious reverence. On platforms like 4chan’s /hbg/, Reddit, and VNDB, Black Souls 2 is frequently listed in top 10 lists of the greatest adult games of all time.

The most common refrain among players is: “I came for the 18+ content, but I left with severe emotional damage.” Fans constantly praise Sushi Yuusha’s writing, noting how the game tricks you into caring deeply about these pixelated fairytale girls, only to rip your heart out later. The community is also highly active in “lore-crafting,” spending hours dissecting the timeline, the outer gods, and the true nature of Alice.

Conclusion

The Black Souls series transcends its medium. It is a masterclass in how to use the interactive nature of video games—along with mature, adult themes—to tell a story about despair, madness, and the desperate, doomed desire to save the ones you love.

If you have the stomach for grimdark fantasy and the patience for old-school RPG mechanics, you owe it to yourself to play these games. Start with the first game to understand the foundations, and then prepare yourself for the absolute emotional rollercoaster that is Black Souls 2. Just remember: whatever you do, watch your sanity, and don’t forget Alice.
