96Neko is a singer from Nico Nico Douga, not an utau. XD
I don't know too much about her, either, but here are a few things I got from her Wikia:
96Neko is often considered more blunt and shameless compared to most female utaites.
96Neko is known to have a huge obsession with Len, as seen in her "Len-kun Nau!" and "Ah, It's a Wonderful Cat's Life" parody covers.
96Neko is also known for her obsession with Tapioca (the pearls in bubble tea). She often posts about it on her twitter, and she has altered the lyrics in many of her parodies to include mention of it.
Here's the link to her Wikia:

Sorry I'm not much help.
