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.

It's quite easy to fall in love with the uniqueness of the game; the characters are one of a kind. I have played a lot of gacha games, and none are like morimens. The artstyle is beautiful and the story captivating. Also, no, and I mean no other gacha game ever, was as generous as morimens. I'm free to play, because you don't even need to spend money to get the characters or wheels (weapons) you want. So, give the game some time and I promise it'll be worth it.

It's been said before but one cannot stress it enough: this game is a hidden gem and it deserves more recognition. The gameplay is fantastic, engaging and even addictive to some degree. It does take a while to get used to some terms and how some team works, but it really clicks. Character design is outstanding and it truly differentiates from other gacha games. Some characters need more than one copy to function, but the game is generous enough to justify it. Truly recommended game!

pretty good, nice stradegy game. Art reminds me of reverse 1999. Each character has a set of cards with their own energy cost, you'll draw random cards each round and have certain amont of energy available. You as the player have 1 ability and each character has an ultimate move. The gacha has pretty good rates and you can choose the deck you want to pull for. Each deck has its own gimmick and you can mix them however you want. So far i have no complains with the game, other than "its a gacha"
