Yeah, I saw that too.
That kid who used pens to stab people was annoying. I'm glad he isn't in it.
He was a doofus.
The only good thing that came from his existence were the subsequent Shizuo responses (or lack thereof)
to his pen stabs.
And Izaya trolling the hell out of him in episode 12.
Those parts were A-A-A-mazing.
