Okazaki
Okazaki works as a Special Police officer assigned to protect Yanagi and his group, though his role in the detective agency he shares with Aiji shows he's far more independent than the title might suggest. He's driven by deep guilt—a colleague once died shielding him, and the trauma never really left. Ever since, he's been on an unspoken quest to find people genuinely worth protecting, maybe as a way to balance the scales.
That past wound runs deep enough that Okazaki will throw himself into danger without hesitation if it means keeping his closest people safe. Fans often read this as less about duty and more about him trying to atone for surviving when someone else didn't. He doesn't talk about it much, but his willingness to sacrifice speaks volumes.
