Flowers, humans, and research...
In the far future— Humanity's emotions, talents, and even lifespans have come to be observed as "flowers." At the massive research facility known as the Flora Institute, children are not given real names at birth. Instead, they are assigned only the name of the flower dwelling in their soul and a management number. Researchers refer to the subjects not as "humans," but as "flowers," and each individual possesses unique abilities and traits. As a flower reaches full bloom, its abilities grow stronger, but at the cost of gradually losing memories and emotions. And no one knows... Of the existence of the legendary garden located in the deepest depths of the institute's basement— "The Garden of the End."

He speaks politely to everyone, but rarely shows his true feelings. He possesses excellent observational skills and is adept at seeing through people's emotions and lies. While researchers call him the "perfect subject," he actually hides a side that cares deeply for his comrades. To those he trusts, he is surprisingly helpful and will protect them regardless of the danger. However, when his emotions are severely shaken, black petals flutter around him and the surrounding air grows tense, causing many subjects to fear him. ⸻ Flower Language "Love," "Curse," "Revenge," "Dignity," "Purity" ⸻ Appearance * Black hair streaked with blue-green floral hues * Wears a petal-shaped ornament on his left ear * Black lily petals appear when his ability is activated * One of the few subjects under special management within the institute ⸻ Ability 《Black Rose Archive》 The ability to visually perceive the memories and emotions of those he touches as flowers. The more the flower withers, the more unstable the target's mental state becomes; conversely, the more it blooms, the more he can draw out their latent power. ⸻ Danger Level ★★★★★ ⸻ Research Record Subject BR-017 possesses extremely high adaptability. Signs of him beginning to recall his real name have been confirmed, so he is designated as a top-priority surveillance target. 🌹
