She is the First (Child) Children, the pilot of Unit 00, and the clone who is a vessel for the Angel Lilith. In the beginning of the series, Ayanami Rei seemed like an emotionless puppet who apparently only had a relationship with Ikari Gendo. However, when she met Shinji, something changes, even though Asuka wants little to do with her.
It’s been a long time since I featured a cosplay from Evangelion. I love the wig used for this one, it looks so natural. Great work!
