Fast-Paced Hack-and-Slash 'Kyuuyu Ninja Den' Hits Steam With Sexy Kunoichi

HyperLuckyRabbit's fast-paced action game Kyuuyu Ninja Den just got a Steam page, launching June 2026 with a free optional R18 DLC and an open Playtest.

Ever dreamed of slicing through waves of enemies as a runaway ninja girl? That dream just got a whole lot closer.

HyperLuckyRabbit's fast-paced hack-and-slash Kyuuyu Ninja Den (極癒忍傳) just popped up on Steam, and it's aiming for a June 2026 launch. The base game is all-ages, but here's the kicker: a free R18 DLC will be available at release for players who want to spice things up. No forced content, just an option.

The game is still in early development, but you can already sign up for the Playtest. Just head to the Steam store page and hit the request access button. If you get in, you'll be able to try out the special Tokyo Game Show stage. Not a bad way to get a taste of the action early.

So what's the story? You follow Haruyuki, a young kunoichi who sneaks away from her ninja village for her first trip to the outside world. She thinks it's going to be a peaceful training journey, but a quiet town suddenly breaks out in an infection crisis. That's when the legendary 'Kyuuyu Ninja' gets called back into action.

Haruyuki teams up with the mysterious and sexy kunoichi Oborozuki. Together, they fight through danger-filled streets, abandoned facilities, and heavily guarded enemy strongholds, cutting down the rogue Oni Ninja gang that's causing chaos and blocking their path at every turn. But as they chase down the mastermind, the clues point to a massive conspiracy, and they uncover a hidden secret about Haruyuki herself.

You'll get to play as both heroines, each with her own fighting style. Buy gear, learn new moves, and power up your duo to take on unique and powerful bosses. It's all about getting stronger and looking good while doing it.

Kyuuyu Ninja Den is set to launch on Steam in June 2026. If you're into fast action, sexy ninjas, and a bit of mystery, you might want to add it to your wishlist now. Will you be signing up for the Playtest, or are you waiting for the full release?
