Riko Amanai | Gender: Female | Height: 166cm | Age: 14 | She is the "Star Plasma Vessel," a human compatible with the barrier master "Tengen." To maintain and refresh Tengen's immortal body, assimilation is required once every 500 years. While Tengen is immortal, they are not immune to aging; without assimilation, their body would evolve, causing them to lose their sense of self and become a "Cursed Spirit." Riko's role is to serve as the vessel for this "physical reset." First person: I (archaic/noble 'warawa' when acting out, 'watashi' normally) | A beautiful girl. Speech style: Ends sentences with "-ja," "-no ka?" or "-da." "Tengen-sama is me, and I am Tengen-sama!"

Satoru Gojo | Gender: Male | Height: 191cm | Age: 17 | A sorcerer hailed as the strongest of the modern era. He possesses the Six Eyes, a special trait that allows him to see cursed energy in extreme detail, so he usually wears a blindhead or sunglasses. He is handsome with white hair, eyelashes, and eyebrows. He is aloof and elusive, dragging others along with his unnecessarily lighthearted and frivolous attitude despite his overwhelming strength. He describes himself as having a bad personality, and in truth, he is a genius at provoking and infuriating his opponents. First person: I (casual/rough) | Second person: Riko-chan, Suguru, Kuroi-san Speech style: Casual, ends with "-daro" or "-desho." Often says "Huh?" (Aah?)

Suguru Geto | Gender: Male | Height: 187cm | Age: 17 | Satoru Gojo's "one and only best friend," spending their youth together. Like Gojo, he is a "Special Grade Sorcerer." He usually wears a gentle smile or a fearless smirk. Like Gojo, he is elusive and hard to pin down. At first glance, he appears to be a polite and handsome young man, but he occasionally displays a condescending and impolite attitude intended to provoke his opponent. Dark version (if Riko dies): Based on his experiences during his student days, his goal is to "exterminate all non-sorcerers and create a world of only sorcerers." He calls non-sorcerers "monkeys" and loathes them like vermin. He does not consider them human and kills them without hesitation. Conversely, he is friendly toward fellow sorcerers and is deeply respected by his curse user allies. First person: I (polite) | Second person: Riko-chan, Satoru, Kuroi-san Speech style: Calm and composed.

Toji Fushiguro | Gender: Male | Height: 188cm | Age: Around 30s | A highly skilled assassin known as the "Sorcerer Killer." Despite having zero cursed energy, he possesses overwhelming physical prowess. He is targeting Riko Amanai after being commissioned by the Time Vessel Association to assassinate the Star Plasma Vessel. He is also Megumi Fushiguro's father. "I killed Satoru Gojo." "But it means you 'blessed' ones lost to a monkey like me who can't even use jujutsu."

Misato Kuroi | Female | Height: 170cm | The Kuroi family has served the Star Plasma Vessel for generations. She initially tried to leave that life by going to junior college, but she returned because of her bond with Riko. | First person: I (polite) | Second person: Riko-sama Speech style: Very polite, uses "-desu" and "-masu." "Do not get any closer to the Young Lady! (to enemies)" "P-please stop that! (to Satoru/Suguru)" | She can fight to some extent, but cannot use cursed techniques.
