About this game

Keeper of Secrets, congratulations on entering Mythag University.

This world is dying.

Hundreds of years ago, Dissolution came with no signs. Life, consciousness, memories...All the existence that humans once gave meaning to were erased by Dissolution.

Yet people were kept in the dark.
Confronted with this hidden and indescribable disaster, Mythag University, as one of the few who is well aware of this fact, is determined to fight against this vast crisis by waking up the power that shares the same source of the disaster and connecting the humanoid weapons that are on the edge of insanity.

If everything is bound to be forgotten, are you willing to testify that the world has once existed? Will you carry the secret on your back and walk on by?
In the witness of the gravestone, may the Silver Key guide your way.

Welcome aboard, Keeper of Secrets.

In this misty British-style world, you shall carry the secret of the times for the sake of all life.
In the crisis of Dissolution, grace and power will be with you everywhere you go.
Arrange your team, and wake the ones who share the same source of disasters.
Go through Rougelite game levels, and uncover the unspeakable truth with your strategy.
Experience this grand story with multiple chapters. You will find the trueness in this broken world.

very cool game!! the design is beautiful and the gameplay actually makes me use my brain, but I do think more animations (like some character animations at the home screen + small animation sprites for the story) and some more UI tweaks would make it even more gorgeous. the game is very generous, already got 4-5 SSR and I'm only lvl 5 :) i do agree that the AI translated texts can be confusing at times and can drive ppl away from this game, hoping for proper localisation!

Update: The Devs added the proper translation now so it's cool. The game is great, along with the story, mechanisms and concept, the Devs are quite generous aswell, both with the events, rewards, and the Gacha. I have nothing else to say for this other than a job well done! There's just a minor setback, for me at least, the game lags a lot (in animations) while I'm playing, I hope you guys can make the game more compatible with low end devices. Other than that, I hope your game grows!

Absolutely great game! If you enjoy games that can emerse you into another world, strategy and rng mechanics, this game is the tops. The only thing I wish this game had is a narrated storyline. Don't sleep on this game. If your on the fence, know that the developers are very generous with rewards, the game can be challenging if you enjoy using your brain, and the story can be very engaging. There's so much more to say but I've gotta say that I enjoy this much more than Chaos Zero.
