Embark on a unique blend of action and simulation as you care for your unobtrusive sister Mio, battling the Abyss each day in A Simple Life with My Unobtrusive Sister.
About this game
Ten years ago, a mysterious giant labyrinth suddenly appeared on the surface of the world. It stretched endlessly into the depths, filled with ancient ruins and terrifying monsters. Adventurers from every land flocked to explore it, chasing fame and fortune in this new age of glory.
But for you, the labyrinth known as the “Abyss” is not just an adventure. It is your only hope.
Your beloved sister, Mio, suffers from a rare illness that no doctor can cure. The only clue to saving her lies somewhere deep within the Abyss. Every day, you descend alone into its dark dungeons, risking your life for her sake while she waits patiently at home.
As the days pass, the Abyss only grows more dangerous.
Will you find the cure before it is too late, or will the depths claim you first?
This is primarily a sister life-sim. Spend time with Mio at home: chatting, watching anime, cooking, and sharing the small joys of daily life, with fully animated and voiced scenes. Your care choices shape her mood and unlock new absolutely wholesome events!
When it is time to pursue the cure, head into the Abyss for focused roguelite runs. Battle monsters, learn skills, gather loot, and push a little deeper before returning home. Each outing supports your simple life together, and each evening brings you closer to the cure Mio needs.
Life with your Sister
After adventuring, return home to enjoy simple life downtime. Whip up meals with gathered ingredients, share adventure tales, play games, or snooze side by side! As you get closer, unlock more interactions!
Animations
Enjoy a wide range of expressive and beautifully crafted animations of your everyday activities with Mio.
Voice Acting
Every line spoken by Mio is fully voiced.
Roguelike! Open World!
Each dungeon dive shakes things up with slightly different terrains, enemies, and treasures, ensuring endless replayability and challenges. Learn and adapt with each exploration to uncover deeper dungeon secrets.
ACT (Armed Combat & Tactics) Real-Time Combat
Ditching turn-based for real-time combat with keyboard and mouse, this game lets you mix skills and gear for a fresh fighting feel. Each dungeon level throws unique challenges your way, demanding tactical skill use and strategy to advance. Dive deeper, and you'll unlock new abilities and gear to beef up your battle prowess."

We’ve reached over 50,000 wishlists!
We’ve reached 50,000 wishlists!Originally, our team thought it would take at least a full month to hit this goal. Many people didn’t believe it was possible to reach 50k in just one month, so hitting this milestone in such a short time has been a huge motivation boost for the develoment team at NLCH! We’ll be bringing you more fun and beautiful content to thank you all for your support!If you haven’t added the game to your wishlist or followed it yet, please do so! About the Steam DemoWe’ve updated the Steam demo with fixes for all known bugs! You can now download it for free and check out the game! Please note: if you’ve already played version 0.82 or higher, don’t transfer your save data to the Steam demo, it’ll cause compatibility issues. Also, the Steam demo has slightly less content than version 0.82, so if you’ve already played that version, there’s actually no need to replay this one. The following illustration was originally meant to celebrate the 50k milestone, but it happened so fast that the art isn’t even finished yet... Hopefully it’ll be ready in time for the 100k celebration.... heheh👀 If you want to get more info about the game, click the buttons below to follow the developer of this incredible game on Discord, Patreon and Bilibili!
