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 fun, I don't need to clear main story to level up my characters like other games. instead, I only need to clear things that are intended for higher leveled players. it's not so hard once you level up your main 4 characters. easy to get the wheel of destinies (weapon) and enlightens (copies) of the characters. pity is 30 and you'll get the limited SSR guaranteed after losing two times. very generous with silvers and pulls. standard characters are also very good for beginners.

Hyper fixation activation. Amazing gameplay and art style, love the story and the voice acting. Would give it six stars but there are only 5. So far my favourite group characters in design are the Aequor peeps, but for game play I lean towards the Ultra faction. Just having an entire turn to command a possibly losing battle and still win is just so appealing and exhilarating.

I find the game amusing! The animations are smooth and doesn't hurt my eyes watching it as I find it soothing, not to mention the characters look unique and the design doesn't go for fan service and I really like that. This game is literally a gold mine because I can never find a game like this. The rewards are super generous and the community is super friendly towards beginner's like me. I hope to find more content that I would enjoy.
