While most of the focus on Nisemonogatari will be on the toothbrush scene (and with good reason), the highlight of Nisemonogatari for me was Shinobu. Nisemonogatari had her first speaking line (I think), and boy did she ever impress me.
It’s really not a surprise that I liked her as much as I did. I seem to have a thing for haughty characters, and Shinobu sure fills that role very well. Her back and forth toying and teasing Araragi was fantastic; I enjoyed it even more than the verbal sparring between Senjougahara and Araragi.
Of course, it doesn’t hurt that she’s an adorable blonde loli who loves eating donuts.
