Using the pen like that is a nice angle. Way too much abyuse just goes for the now kind of ho-hum eyeball gouging/flaying/general impalement/etc. It's nice to see something more low-key and precise like that, that doesn't immediately reduce the yukkuri into a pile of screaming bean paste. Plus her reactions are kind of adorable in a messed up way.
