This is Ayanami Rei papercraft from Neon Genesis Evangelion series.
Ayanami Rei is a fictional character from the Japanese media franchise Neon Genesis Evangelion created by Gainax.
She is the First Child and pilot of the Evangelion Unit 00.
Rei Ayanami was the product of Gendo Ikari and Kozo Fuyutsuki attempt to retrieve Yui Ikari from EVA01 using her salvaged remains.
Among her papercraft we posted before, this is a proper looking one for now and really worth it to build.
Rei papercraft requires 9 sheets of paper to build. Assembling is medium difficulty.
