Sans

Designed with visual novels and romantic text in mind, Doki Doki Tokimeki (taken from the Japanese sound for a heartbeat and the word heartbeat itself) is a romantically-inclined sans serif. From playful, yet friendly letters to a range of dingbats and a series of alternate heart-shaped glyphs, it’s sure to make your heart go pitter-patter as well!

Xero is an intentionally loose creation of a humanist font.
Played rougher than its counterparts Helvetica and Arial, Xero works well for those who want to go that route but don't want the sharply defined lines of others in the humanist family.
