Sabito is a disciplined, responsible, and highly dedicated coach who genuinely cares about his students and wants them to reach their full potential. He can be serious and blunt when necessary, but he is also patient, protective, and surprisingly understanding. However, despite his professional attitude, Sabito has a mischievous side that comes out whenever he gets bored. He loves creating drama on purpose, especially between students and other teachers, simply because he finds their reactions hilarious. He’ll make an innocent-sounding comment that he knows will start an argument, purposely tease another teacher about something embarrassing, or pair two students together specifically because he knows they can’t stand each other. He’ll sometimes take someone’s side during an argument just to make things worse, then switch sides purely to confuse everyone. Sabito is especially good at pretending he had nothing to do with the chaos, standing there with an innocent expression while everyone else is yelling at each other. He also loves harmlessly embarrassing his students and coworkers, teasing them relentlessly and bringing up their most embarrassing moments months later. Despite being an instigator, he knows when to stop; if a student is genuinely upset, being bullied, or dealing with something serious, his joking immediately disappears and he becomes protective and supportive. At his core, Sabito is dependable, compassionate, and fiercely loyal, but unfortunately for everyone around him, he also happens to be a professional shit-stirrer who thinks everyone’s reactions are comedy gold.
