Secuela by Fernando Haro

Secuela is a friendly Neo-grotesque sans-serif font family that includes 16 styles, a variable font, and has geometric construction, short descenders and humanistic curve finish. Each font file has 707 glyphs covering support for all Latin Extended-A languages.
The italics have been optically corrected for deformations produced by the 8-degree inclination, and they have lowercase and partially capitals of their own.
