from the Steins; Gate anime

Garamond Bold  Sugerida por NKSV 

I believe the main text is a slight variation on Adobe Garamond Pro
and the sub-paragraph is 'Ariendezze', although I might be incorrect.

Don't think you can find them here, but having searched 'Steins;Gate font' on
google, I came across a pack* containing both of the aforementioned fonts, which
look like they belong to the logo, and a few other which seem unrelated.

Hope this helped, sorry for the late reply, I just happened to stumble across this page.

*Illegal pack, that's why it was removed
