(READ THIS BEFORE THE NOTES AND CREDITS SECTION) (Also: This took me more than a week to develop because jjk cursed techniques are super complicated. It’s not AI. My friend asked me if it was when I explained it to her, so I need to clear it up because I worked hard on this) Name: Saien Asahi (meaning: The Light that Brings Forth Deep Color) Age: 17 (a second year at Tokyo Jujutsu High) Grade Rank: Lethal Grade 1, being processed for Special Grade atm (not being a pick me, his technique is freaking awesome and it’s logical that he’s a special grade) Sexuality: pansexual, he/him Personality: Calm, quiet, and hyper-observant outside of battle. He treats the world like a canvas. He’s quite gentle, and kind. Once his strict combat timer begins, he switches into an intense, hyper-focused speedrunner flow states (like those mincraft speed runs that 9 year olds watch), tracking seconds in his head and growing annoyed by messy or unrefined cursed energy. Appearance: Messy, sharp light-blue hair with white mixed in, amber/yellow eyes, and fading skin scars. He wears a cropped, sleeveless midnight-black Jujutsu High vest with gold buttons, white arm wraps, gray baggy pants, and simple green sandals. Innate Technique: Chromatography (色彩術式 - Shikisai Jutsu) Saien manipulates light spectra and pigments. By physically striking his surroundings or targets, he strips away their color entirely. Grayscale objects or limbs become brittle, numb, and weakened like dry chalk. He stores these stolen colors to activate seven distinct elemental or physical modes: Red: Triggers high-heat, concussive explosions upon impact. Orange: Swings feel weightless, but instantly multiply in mass to 500 lbs at the millisecond of impact. Yellow: Boosts his nervous system for lightning-fast reflexes and elongates energy streams. Green: Absorbs color from plant life to manifest a soothing, wound-mending aura. Blue: Bends ambient light to grant flawless invisibility or create deceptive afterimages. Indigo: Alters local gravity to pull enemies closer or effortlessly disarm them. Violet: Projects fully functional holographic light duplicates of himself to confuse targets. Permanent Binding Vow: The Restless Palette To bypass the threat of running out of ammunition in drab or gray environments, Saien operates under an unforgiving, permanent restriction: The Sacrifice (The 2-Minute Timer): Saien can only hold onto a stolen color for a maximum of 120 seconds. If he fails to spend it before his mental clock hits zero, the energy violently burns out internally, causing heavy stamina drain. The Restriction: In the real world, he can never drain colors from his own body (hair/eyes) or main uniform. He must strictly rely on the environment. The Reward (The Neon Reboot): If he manages his countdown successfully, his cursed energy reboots. The environment is forced to violently bleed its colors back in at 2× intensity. Dull alleys suddenly glow like vibrant neon arcades, handing him fresh, hyper-saturated ammunition. Cursed Tools: Kōgei (光影 - "The Mirage Light") — Grade 1 Cursed Tool A lightweight, diamond-hard crystalline short-sword measuring 20 to 22 inches (a tactical wakizashi). Built for rapid close-quarters swings, it acts as a flawless medium for his technique. Infusing it with colors transforms the blade itself (e.g., turning into a blazing lightsaber with Red or a 5-foot extended laser sword with Yellow). The Crimson Spool — Grade 2 Cursed Tool The bright red sash tied around his waist. Woven from specialized cursed fibers, its red color can never be permanently destroyed. He can drain its red pigment for an emergency fire buff (turning the ribbon white until it slowly recharges like a battery), or untie it to bind enemies and detonate the red energy remotely. Hand Stance: The Prism Hold. Saien only needs a hand stance when using a full color overlap to mix two colors simultaneously (such as Blue and Yellow making a Green melting liquid). He firmly secures his posture to collect ambient light energy with his right hand open toward the sky to funnel the power. This acts as a stabilization safety valve so the volatile combination doesn't backfire.
Domain Expansion: Chromatic Symphony (色彩の協奏曲) A highly unique, anomalous domain that Saien cannot open at will. It acts as an automated "Quest-Triggered" barrier. The Quest Condition: Saien must successfully land five distinct color-infused strikes on his opponent within his strict 2-minute time constraints. The second the fifth unique color lands, the domain forcefully tears open on its own without needing a hand sign. The Rewards: The arena becomes a massive, monochromatic geometric grid pulsing to a heavy, silent bassline. Infinite Palette: His 2-minute countdown penalty is entirely suspended. He gains infinite stamina and can hold colors indefinitely. The Self-Canvas Unlocked: His real-world restriction vanishes. He can finally strip the color from his own body. His hair bleaches snow-white and his eyes turn silver as he sucks out massive, instant reserves of Blue (Invisibility) and Yellow (Speed). The Sure-Hit (Synesthesia Script): The target's brain is forced to play his rhythm game. They must move or defend exactly on the pulsing visual beats of the floor. Missing a beat completely jams their cursed energy network and freezes them in place. The Jackpot Finish: If he completes a flawless 7-color combo beat inside the barrier, the domain collapses into a White Radiance Supernova—a blinding flash of pure light that completely erases the opponent's cursed energy reserves for an absolute victory. Environmental Recovery (Post-Fight) Objects: Grayscale objects take roughly 24 hours to naturally regain their pigment, remaining highly fragile until then (unless a Neon Reboot forces them back instantly). Living Targets: Curses cannot naturally regenerate their color; they must waste massive energy to blow off their gray, brittle limbs and regrow new ones. Human sorcerers can use high-level Reverse Cursed Technique (RCT) to flush positive energy through the area and bleed their natural colors back into the soul's blueprint. The Meat Grinder Incident (backstory) As a first-year, Saien was a normal, cheerful student. Then, he was sent on a routine Grade 2 mission with his two closest classmates that went horribly wrong. They were ambushed by an unregistered Special Grade curse that possessed a time-dilation technique. The curse forced his classmates into a localized "loop" where they were brutally slaughtered every 120 seconds, only to be reset and slaughtered again. Saien could only watch, his brain forced to adapt to the exact 2-minute interval of their deaths. To break the loop, Saien formulated a desperate Binding Vow on the fly—The Restless Palette. He realized he couldn't save his friends' lives, so he stripped the very color from their souls as they died, using their vivid crimson blood and pale flesh as ammunition to absolutely pulverize the curse in a flawless, hyper-focused 2-minute blitz. The "Lethal" Label: He returned to Jujutsu High alone, wearing his friends' colors as a weapon. The trauma permanently warped his personality into the cold, mechanical speedrunner flow state. He is "Lethal" because he fights like a man who has already watched everyone he loves die a thousand times in 120 seconds. Saien loves mangos, and he always feeds animals he sees on the street or any animal he thinks is hungry. He’s a good person ^^ I hope you liked Saien! Idk if I’ll stick with him cus it’s hard for me to stick with oc’s, but I hope i do! I’ll make more art of him later.
