Syllable is unixesque Operating System for x86-compatible PCs, which amazes by its speed and its beautiful graphical user interface. It uses a modular, monolithic kernel. Numerous applications (most of them console-based) have already been ported to it, like the Apache web server or Emacs.
Syllable-tan likes to skate, which symbolizes both her amazing speed and her beta status (she still learns and crashes a lot). She wears elbow-protectors and a body-protector slightly reminding of the box of 98-tan and 98SE-tan but with the Syllable-logo on it. Her hair is reminding of the sun-esque Logo of Syllable.
