The final panel with Ichigo ripping out the tongue was probably the coolest panel so far. I rather liked how the onomatopoeia "Shwuk" was placed in-between them, almost as if it was to simulate the blood that would've come from a non-dead opponent. That action had a lot of impact to it.
The backstory of the serial killer and the parakeet is a bit more comical than serious, so it doesn't really land any emotional blow for me.
