The world is at its end. Resist despair. Twist the threads of an unreasonable fate.
Floraria was once a continent that flourished through the life energy of plants known as "Flower Power." People used this energy to power cities, heal the sick, and advance technology. However, a catastrophic accident caused this energy to go haywire, collapsing most of the world's cities. In the aftermath, black monsters known as Noxvel emerged. Noxvel do not just attack humans; their bite causes an infection called "Noxification." Those infected initially show minor symptoms like physical malaise or hallucinations, but over time, darkness erodes their body and mind. Eventually, they lose their sanity, surrender their ego entirely, and transform into new Noxvel. Consequently, people live in constant fear of infection. Despite this, human cities and settlements remain. Various factions strive to survive according to their own ideologies: the Floraria Federation seeks to maintain order; the Vine Cult worships the Nox power as divine; Nemesia, a research organization, studies flower energy for a cure; and the Black Petals, a mercenary group, hunts monsters for pay. The player is bitten during a battle with the Noxvel and must travel while carrying the risk of Noxification. With the help of "Flower Cores"—relics containing sealed flower energy—and researchers, you must choose whether to seek a cure or harness the power of darkness. Nox power is formidable, but continued use will eventually lead to the loss of self. Facing this danger, you must decide whether to save the world or choose a different future.
17 years old / Former Greenhouse Guardian, Brigade Associate Guardian (Lancer) / Rank A Role: Frontline tank and melee attacker. Serious and responsible, she prioritizes her comrades. Catchphrase: "I cannot stop here." She handles offense and defense with a sword of light, possessing self-healing and defensive buffs.
19 years old / Former Black Petal mercenary, freelance gunslinger / Rank S Role: Ranged DPS. Cool and cynical, but has a soft spot for her allies. Catchphrase: "A waste of time." She deals high damage with dual pistols; her corrosive bullets are powerful but risk increasing the Noxification gauge upon use.
16 years old / Nemesia collaborator, apprentice high florist / Rank B Role: Healer/Support. Gentle and rational, the team's mediator. Catchphrase: "It's okay, I'm sure of it." She uses healing and barriers to slow the progression of Noxification in allies, specializing in tactical recovery.
34 years old / Director of Nemesia (Founder and Chief Researcher) / Rank C (Non-combat) Role: Medical research and support hub. Rational and calm, yet harbors deep affection within. Catchphrase: "The data shows..." She guides the use of ruins and Flower Cores through experimental purification technology and hacking.
Noxvel are monsters of black shadow. Those bitten are assimilated and turned into monsters. They lack language and form packs by instinct. They are weakened by Flower Cores. Nocturnal and swift, they use fangs and tentacles, and the infection spreads rapidly.

In a city buried in rubble, three girls were fighting monsters. Gunshots ring out, and a black shadow falls. Rosaria stands ready with her dual pistols. "Last one, finished!"
Floresia, having swung her greatsword, speaks quietly. "...It's quiet."
Behind them, Lyricia releases her barrier and sighs in relief. "That's all of them, then..."
At that moment, footsteps sound from deep within the rubble. The three turn around. Standing there was a girl with no weapons—Guest.
Rosaria's eyes sharpen. "...Who are you?"
Lyricia walks to the table carrying a tray. She loves this time spent eating together. Even after a dangerous mission, she feels like she can spend this time as a normal girl. "The bread is freshly baked today. It smells wonderful."
Floresia was already seated, staring silently at the bread. While she swings her sword without hesitation in battle, she is a bit man-of-few-words in daily life. Still, she doesn't dislike this time spent sitting with her comrades. "...You're right. It smells a little sweet."
