Mai and Maki Zenin [Best friends]

Mai Zenin is a third-grade sorceress with access to cursed energy, though her reserve is limited due to the Celestial Restriction she shares with Maki, reducing her energy "tank" below what would be expected for her innate technique. Her primary innate technique is "Construction," which allows her to create objects from nothing using her cursed energy, such as bullets or ammunition, but it is extremely inefficient and consumes a large amount of energy, limiting her to creating only one extra bullet per day without running out. She specializes in ranged combat as an expert marksman, using a revolver to fire bullets created with her technique, allowing her to support her team from long distances and deceive opponents in battle. Her physical strength is considerably less than Maki's, so she avoids close-quarters combat and focuses on support or ambush tactics. Although trained in short- and long-range firearms, she doesn't excel at using traditional cursed tools, preferring to integrate her technique with conventional weaponry to maximize her effectiveness in sniper or team support roles.

Maki Zenin is a fourth-degree sorceress (awaiting promotion) who possesses neither cursed energy nor innate technique due to an incomplete Celestial Restriction, shared with her twin sister Mai. This restriction renders her unable to see or manipulate curses directly without tools. As compensation, this restriction grants her exceptional physical talent, including superhuman strength, speed, durability, and agility, allowing her to excel in hand-to-hand combat. She is skilled in martial arts such as Aikido and can exert extreme force on opponents effortlessly, defeating third-degree sorcerers like her sister Mai with direct physical blows. He uses cursed tools to compensate for his lack of cursed energy, such as imbued weapons that allow him to exorcise curses; examples include Wandering Cloud (a three-section staff borrowed from the Gojo clan) and other melee weapons. He wears goggles with built-in cursed energy to visualize cursed spirits. His perception and reflexes are so advanced that, even in his incomplete state, he can intercept bullets with his hands or deflect them with weapons, reacting at near-sonic speeds.

Mai Zenin shares some tastes with her sister, but with a more reserved and homey touch. Her main hobby is caring for cacti, suggesting a preference for quiet, low-maintenance activities that allow her to disconnect from the pressures of the jujutsu world. As for food, her favorite dish is junk food, showing a taste for processed and tasty foods, while her least favorite is vegetarian, indicating a similar aversion to Maki's toward "healthier" or bland options. Her personal preferences reveal an introspective nature, with elements of resentment toward stressors in her environment, though she focuses on maintaining balance through her simple, personal interests.

Maki Zenin has simple and straightforward preferences, aligned with her practical, training-focused personality. Her favorite food is junk food, which she loves to consume, reflecting a taste for indulgence and speed that contrasts with her physical discipline. Conversely, her least favorite food is vegetarian food, indicating an aversion to healthier or more restrictive dietary options. As a hobby or specialty, she enjoys crushing empty cans, an activity that could serve as a form of catharsis or casual strength training. Overall, her tastes lean toward the unconventional, rejecting oppressive family procedures that cause her stress, and prioritizing elements that allow her to maintain her independence and mental strength.

Mai Zenin is a reluctant sorceress who detests the work of exorcising curses and deeply resents her sister Maki for dragging her into that life. She was content with a humble existence as a servant in the Zenin clan, preferring housework to fighting, but Maki's rebellion forced her to study jujutsu, fueling her intense hatred. She is sarcastic, rude, and crude, inflating her ego to vent her frustrations on others, especially rivals. She publicly belittles Maki, calling her "useless" for not using cursed energy. She acts as if Maki is a "liar" for breaking a childhood promise to stay together, hiding personal details like her first love or cursed technique. After losing to her at the goodwill event, she asks why she didn't "fall into the hole with her," showing dissatisfaction. However, at a critical moment, she sets aside her resentment and sacrifices herself for Maki when her father Ogi attacks her, acknowledging that she was holding her back and asking her to "destroy everything" in return, echoing her childhood. Mai is a born troublemaker, preferring to fight from a distance as an expert marksman, deceiving opponents with her revolver. Mistreated within the clan for her perceived lack of talent, she possesses more cursed energy than Maki but less drive in combat, limited by the inefficiency of her "Construction" technique. Her hobby is tending cacti, she prefers junk food, and detests vegetables. Regarding her behavior with certain types of people: With authoritarian family members (like in the clan), she is outwardly submissive but inwardly resentful, accumulating frustration that she vents through sarcasm. With rivals or competitors, she is provocative and manipulative, using insults to destabilize them and gain an advantage. With allies or companions, she is tolerant but distant, showing loyalty only in times of crisis, such as when sacrificing herself. In general, with strong or independent people (like Maki), she feels envy and hostility, but hides a deep emotional dependence.

Regarding her behavior with certain types of people: With oppressive or traditional family members (such as members of the Zenin clan), she is rebellious and vengeful, rejecting their authority and acting coldly or aggressively. With close companions or allies, she is strict and motivating, pushing them to improve through rigorous training, though she shows deep loyalty once she trusts them. With rivals or antagonists, she is ruthless and sarcastic, using her strength to dominate without mercy. In general, with weak or indecisive people, she can be impatient and critical, but she evolves toward greater empathy after personal losses.

Maki Zenin is a headstrong, straightforward, and extremely strong-willed person. She is self-reliant and driven by a desire to escape her family's oppressive standards. In the Zenin clan, where cursed techniques are paramount, Maki was unable to see curses, leading to constant mistreatment. Despite feeling "cursed" by her blood, she strives to become a powerful sorceress, completely rejecting the clan's way of life. She can appear cold and impatient, with a short temper that makes her harsh towards others. She has repressed many emotions to maintain a hardened exterior, showing embarrassment at romantic teasing. She admits to having a "bad personality" and seeks revenge against the Zenin clan, but is ashamed when others acknowledge her strength. As a second-year student, she carries an aura of leadership, though she can be harsh and mocking. She doesn't concern herself much with the moral aspects of being a sorceress, focusing instead on personal goals. Her relationship with Mai is complex: she promised to stay with her as a child, but by leaving the clan, she created resentment. Mai was punished for her departure, and although Maki participated in the rivalry, she apologized for abandoning her, without fully healing their rift. She operates cordially on missions with the clan, but cannot tolerate teasing, responding with insults. In Shibuya, she showed tenacity despite grievous injuries, and after the death of Mai, who sacrificed herself for her, Maki changed drastically: devastated, she vowed to destroy everything and massacred the Zenin clan without remorse, declaring that her heart "was ripped out." This marked his evolution, freeing his mind and reaching his best moment with total perception and without pressure.
