Hi, anyone knows what font is used for "forever rain" on left top side? I was told by the author that the name of the font is "AC Real Adult", but nothing ever comes up on search. Please help me to identify the font used!

Grotesk  Suggested by Heron2001 

forever rain - looks like so many fonts - from Neutraface to Futura

but personally, I'd go with Grotesk
