It's SIEN from Ecchi.Iwara.TV, but he deleted this as well as a few others related for…..reasons unknown. He gave a vague answer, but yea it's gone. Makes non-guro great stuff though. Amazing animations.
who is this character?
You mean there were more of those videos?
There were yes, but not anymore. Also, I do not know who the character is but she might be someone from Honkai Impact 3 since the majority of those deleted vids were about that series.
It’s Poppy’s Final form from Xenoblade Chronicles 2
I found and uploaded those deleted Honkai Impact 3 videoshttps://mega.nz/#F!nro1BChB!9ViYJBnck5IvzhhBTp1pFw
