The filming is trash, terrible angles, unnecessary close ups. Amazing cosplay you dont get to see from any other angles, just awkward videos in general. Shame I still consider her hot af.
If you look at her older pics from 2011-2013 she had a very wide/round jaw. Based on how wonky her cheeks/jaw/lip area looks now I'm thinking she had her jawline shaved down to more of a point.
She probably felt uncomfortable about her body and started to get surgery to get to ideal woman body that magazines promote!
As she lives in Japan maybe it's worth getting the modification specially if she works in Hostess bars (good money on that profession), would easily attract more customer.
