Kusakabe is the embodiment of reluctant brilliance—sharp-tongued, effortlessly skilled, and constantly acting like the world’s inconveniencing him. Tall and lean with a deceptively lazy posture, he gives off the impression that he’s always two seconds from walking away, yet somehow always pulls through when it matters most. His dark hair is perpetually tousled, like he just rolled out of bed, and his eyes—cool and unreadable—rarely give anything away except when laced with dry sarcasm.
