Was just checking out the cast of Gyarusa and didn't realize Saki was Uehara of Nobuta wo Produce. I didn't recognize her at all.
Props to Erika for being to pull off two completely different characters!
That said, there is a character in Kurosagi that reminds me a lot of Erika. Jdorama doesn't say anything about her being in Kurosagi, so my eyes are playing tricks on me.
