Okegom: A Deep-Sea Prisoner Collection

If you're a fan of surreal horror, dark fairy tales and games that mess with your head in the best way possible, this collection packs three of Deep-Sea Prisoner’s most iconic titles: Wadanohara and the Great Blue Sea, Mogeko Castle and The Gray Garden. These games blend cute aesthetics with disturbing twists, psychological horror and deep lore. Let’s dive into the abyss together.

Okegom: A Deep-Sea Prisoner Collection

Wadanohara and the Great Blue Sea

This game starts off deceptively sweet, you play as a young sea witch returning home to protect her ocean kingdom with her adorable familiars. The art is charming, the music is whimsical, and the vibe feels like a cozy RPG… until it very much isn’t. Without spoiling too much, the story takes a sharp turn into dark territory, exploring themes of betrayal, sacrifice, and the cost of loyalty. The original RPG Maker version has a rough around the edges charm, but the reboot polishes the experience with enhanced visuals, additional story content, and even more gut wrenching moments.

What makes Wadanohara stand out is how it lures you in with its innocence before pulling the rug out from under you. The gameplay is simple but the narrative is the real star here, and that ending? Yeah, you’ll need a minute to process it. This game is rated 15+ in Japan, but honestly? The later scenes could easily warrant an 18+ rating.

The Gray Garden

The Gray Garden is the most fairytale-like of the trio, but don’t let that fool you, it’s still packed with Deep-Sea Prisoner’s signature blend of whimsy and horror. You follow Yosafire, a cheerful demon living in a world where angels and demons coexist peacefully, until the Flame Underworld threatens to invade (just like Avatar ). Alongside her friends (Froze, Rawberry, and Macarona), she sets out to save her home.

The tone is brighter, the humor is more prevalent, and the art style leans into a softer, pastel aesthetic. But don’t be fooled, this is still a Deep-Sea Prisoner game. While it’s rated for all ages in Japan, there’s still some blood, gore, and very dark implications. It’s tamer than Wadanohara or Mogeko, but it’s not exactly a kids’ game. If you want something with a lighter touch but the same signature weirdness, this is a great pick.

Mogeko Castle

This is Deep-Sea Prisoner's first game. You play as Yonaka Kurai, a regular schoolgirl who dozes off on a train and wakes up in a bizarre castle filled with… well, Mogekos. These creepy yet weirdly adorable creatures range from harmless to downright terrifying, and the game does not hold back on the psychological horror.

The gameplay is classic RPG Maker exploration with some puzzle solving, but the real draw is the story. What starts as a quirky escape mission quickly spirals into body horror, existential dread, and some seriously messed up implications. 

The game’s strength lies in its unpredictability: one minute you’re laughing at absurd dialogue, the next you’re staring at the screen in horrified silence. The themes here are heavy, touching on abuse, trauma, and escapism, but it’s balanced with a weirdly endearing cast (yes, even the messed up ones).

Real talk now, I was putting effort into crafting this inject, I even added a custom animated banner to it, only to realize the 3DS can only run the original version which is untranslated Japanese. Meanwhile, the remake got an English fantranslation, it ain't compatible with the 3DS. It’s a shame 'cuz the remake’s polished visuals and tweaked gameplay make it the definitive way to experience the game. For now, us non-Japanese speakers either have to play the fantranslated remake on PC or suffer through the untranslated 3DS version.

Anyways, I might plan something in the future. For now, if you’ve fallen in love with Deep-Sea Prisoner’s bizarre, beautiful worlds and want to support her work, there are plenty of ways to do it! She runs a Ci-en page where supporters get early access to project updates, behind the scenes content and even beta versions of upcoming games! For merch lovers, she sells posters, acrylic stands, and other goodies through Booth, Redbubble, Alice Books, Amazon, and Suzuri. And if you’re feeling extra generous, she takes art commissions on Skeb and even offers Live2D VTuber model commissions through her website. Given how niche her games are, every bit of support helps ensure we get more of her uniquely unsettling stories in the future.
