Chapter begins with Kenpachi and Kenpachi still fighting, and we’re entering flashbacks. It shows Unohana, as former Captain of Squad 11, turning the place upside down, like some sort of massacre. Lots of Corpses…but a young Zaraki came out of the pile of Corpses.
And stabs Unohana in the neck, that would explain with scar she had. Back to the present, still fighting, Zaraki slices Unohana. Back to flashbacks, you losing to Ichigo, you beating Nnoitora, Unohana thinks that Zaraki is handcuffed to himself to his own detriment.
From their first encounter, reaching their level for killing, congratulations, that’s Unohana’s Sin. But the truth, even she was no match for him. But she slices Zaraki. Zaraki got slaughtered, but still around. Chapter ends, Zaraki slices Unohana
Detriment- Injury; Damage
