When Seizo finally left the Gotei 13 with his head held high, I felt a surge of respect for him, but Ikkaku finally acknowledging him, even just for a moment, really cemented Seizo's departure as something meaningful. I've always seen Ikkaku as so stubborn, so to see him offer that kind of respect was a surprising moment of growth for both of them, showing that even the fiercest warriors can recognize true honor.
