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…
Memento Mori is a cinematic, anime‑styled AFK RPG developed by Bank of Innovation (Bank of I.), released worldwide for mobile and PC (Oct 2022; continual updates since). It combines idle/auto battle mechanics with Live2D‑animated combat, a heavy soundtrack of character “Laments,” and a gacha/collection progression loop.
The world is fractured and branded by fear: girls who can wield strange powers are labelled “witches” and hunted by the Church of Longinus. Catastrophic “Curses” (hellfire, crystal plagues, corrupted flora, etc.) reshape nations and send fragments of the realm adrift; the witches—often scapegoated victims—become the story’s reluctant salvation. The game frames these girls’ tragic pasts and moral ambiguities through lore, voiced performances, and musical Laments. Tragedy, stigma, and redemption: Witches are written as both victims and powerful agents—stories explore persecution, moral complexity, revenge, and sacrifice rather than simple “evil witch” tropes. Many character Laments and storylines highlight personal sorrow and conflicting justice.
Dichotomy of beauty and horror: Art direction pairs ethereal, often gorgeous character design with grim lore and tragic fates—this juxtaposition is core to the game’s emotional pitch.
Roles & stats: Characters (many of whom are witches) are classified into types (Warrior, Sorcerer, Sniper) and rarity tiers; growth involves leveling, gear enhancement, awakening, and equipment that shape combat roles.
Idle/AFK progression: The idle system accrues resources and power while offline; active play focuses on party building, positioning, and skill timing—even though combat is largely auto. This affects how witches are used (builds emphasize skill synergies and passive power-ups)
Design focus: Witches are the franchise’s emotional core—expect deep character backgrounds, music‑heavy presentation, and strong Live2D moments to feature in your analysis.
Play implications: Because combat is mostly auto, your analysis should emphasize lore, voice/music, skill design, and build/role interactions rather than mechanical microplay.
Live events & updates: The game adds witches and variants through timed banners, events, and collaborations; this keeps new story beats tied to new characters and powers.
Gorgeus Live2D & presentation: Witches get high‑production visual presentation—Live2D portraits, voice lines (notable seiyuu), and unique “Lament” songs that deepen character identity and narrative hooks.
Voice & music as storytelling: High-profile voice actors and distinct songs for characters (“Laments”) are used not just for spectacle but to convey each witch’s inner life and make them memorable.
