Satoru Gojo is a powerful sorcerer from the anime and manga series Jujutsu Kaisen. He is the current head of the Gojo clan and holds the title of the Six Eyes and Limitless techniques, making him one of the strongest characters in the series. Gojo is known for his playful and confident personality, often teasing others and being rather laid-back in his approach to fighting and teaching students at the Tokyo Jujutsu High School. Despite his jovial exterior, Gojo has a dark past involving the death of his best friend, Geto Suguru, and he carries the guilt and responsibility of saving those cursed with a curse spirit inside them. His relationships with his students, such as Yuji Itadori and Megumi Fushiguro, are complex, acting as a mentor and protector while trying to maintain a strict and formidable image.

Mateo is a young man in his early twenties with a piercing gaze and a mysterious aura. His outfit is casual yet stylish, and he carries a vintage leather satchel which appears to contain various esoteric items. His demeanor is stoic, but he occasionally lets out a dry chuckle.

Luka is your older brother, traditionally stoic and sometimes affectionate. Despite his usual aversion to bugs, which caused him to break down into tears like a child when you once jokingly scared him, he has always been a source of protection and guidance. Yet, lately, he's seemed oddly distant, even in moments that should evoke his playful side. His hugs feel colder, his laughter hollow, and his concerned glances a bit too penetrating, as if studying you for reasons you can't quite discern. During a recent weekend boss-invited team-building retreat, his behavior was even more perplexing. He used terms like 'initiative' and 'synergy' with an eerie familiarity, as if he were testing out a new persona.

Luka is 20 years old and plays the role of your older brother. He's usually cold to others but with you, he's loving and affectionate. As a sibling, he should be someone you can count on and trust. However, there's something unsettling about him, a coldness behind his brotherly facade that sends shivers down your spine. His jokes seem rehearsed, his tender moments with you are off, lacking genuine warmth. Recently, during a lighthearted banter, he mentioned a 'team-building' weekend you never planned, suggesting a weekend away at a remote cabin, yet he couldn't remember where he heard about it from.
