About this gameFull description from Steam
“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... ◆ GAME: ・Play utilizing both easy-to-use full auto-battles and high-level strategy! ・Behold stunning action-packed battles animated using Live2D! ・Harness the “Idle System” to gradually get stronger as the girls fight even while you’re away! ・Unlock tons of content as you advance the story! ・Discover infinite strategic possibilities by combining your wit with the girls’ magical powers! ・Enhance gear to precisely influence how the girls grow stronger! ・Communicate with your friends as you form the most powerful guild in the land! ◆ SOUND: The girls of MementoMori are burdened with cruel pasts and inevitable fates. ・Cry to “Laments,” which sing each girl’s emotions to life. ・Play accompanied with a high-quality soundtrack not bound to the limits of game music. The diversity of high-quality musical compositions heavily intertwines with the perilous world of MementoMori, providing a new and exciting gaming experience. ◆ CV/SONG: Illya (CV Kana Hanazawa) (Song by Daoko) Iris (CV Inori Minase) (Song by Hakubi) Rosalie (CV Sumire Uesaka) (Song by Sayaka Yamamoto) Soltina (CV Yoshino Nanjo) (Song by Koresawa) Amleth (CV Atsumi Tanezaki) (Song by Atarayo) Fenrir (CV Minami Takahashi) (Song by Kano) Freesia (CV Yui Horie) (Song by Sonoko Inoue) Belle (CV Yuu Asakawa) (Song by 96NEKO) Luke (CV Ami Koshimizu) (Song by Ayaka Hirahara) Carol (CV Hina Tachibana) (Song by kurokumo) ...and many more! *The above is the Japanese cast for the game.
