In a land devastated by curses, witches—once hunted and blamed for calamities—set out to free the fractured world from darkness. The story follows these girls and the powers and pasts that shape their journeys.
Build a team of characters and progress through quests by battling enemies and bosses. Combat runs automatically; players focus on team composition and strengthening characters with materials, equipment, and limit breaks.
The idle system gathers resources while you are away, supporting gradual character growth and further story progress. The game also includes PvP and guild features, alongside character stories and a song associated with each witch.
Many reviewers praise the watercolor-like artwork and soundtrack, especially the songs associated with individual characters. Some enjoy the relaxed, short-session pace and gradual idle progression, while others appreciate the characters and their stories. A recurring criticism is that battles require little direct input and progression can become slow; reviews also disagree on how rewarding free play feels, with several describing gacha and upgrade systems as costly or restrictive.
“All roads lead to our ‘Goodbye.’”
Boasting an epic soundtrack that can turn the world of gaming on its head, and some of the most stunning designs ever seen in a game, Bank of Innovation’s newest title, MementoMori, is finally here!
Songs performed by many renowned artists enhance the rich world of MementoMori.
*We recommend playing while wearing earphones or headphones.
◆ STORY:
A tale of “justice” woven by girls whose fragile hearts verge on shattering...
There are girls who many call “witches.”
Although they themselves are ordinary, they can wield slightly extraordinary powers.
However, when calamity spreads throughout the land, witches begin to be feared and detested.
Before long, the Church of Longinus commenced what would be known as “The Witch Hunt.”
“Witches are to blame for this calamity. If we kill them, then the calamity will vanish along with them!”
Witches are executed one by one.
But one day, as madness seizes control of the world, it is suddenly overrun by “Curses.”
A country incinerated by hellfire. A kingdom consumed by crystals. An empire purged by the Tree of Life.
Such are the woeful desires of those who are called “Witches of Qlipha.”
Without any means to defend themselves, nation after nation falls into ruin, until finally—
The fractured land is sent adrift high into the sky.
Meanwhile, the people have yet to take notice.
From within these girls cursed to be witches, there emanates glimmers of hope.
In order to save their decimated world, these girls set forth liberating the land from darkness.
For they believe that it is the right thing to do...
