So as it says in the title I will reveal how ink brought u to life 

Flash back 

     The world fades from view and u drift away you hear ink call your name constantly before dying. "Y/n y/n please don't fade please we need you please".  You say three words before dying "I love y-yyou". "Y/n no no no Y/n please please". "Ink it's time to go we can take her but we can't save her". 

Inks POV 

I pick up Y/n and teleport with dream. "I think I know a way to save her but it may harm all of us including her". I get some paper and my brush and start painting. After awhile I finished and ask for everyone to put some of their abilities into it.  I then touch it and I see y/n in the background breathing a little. We teleport back and tell them she's back. 

So yeah that's how u came to life
