Kvadrug is divided into its two main forms: Xtrovert and Hikikomori.

- Xtrovert: The square is the base, and the dots represent the external glyph anatomy.

- Species division: • By mode: solid, outline, rounded, rough • By tone: monochrome and colored fonts (cf)

* Regarding "cf" variations, there are several presets, and for additional color options, use manual methods like hue/saturation or color range selection + fill until we update the appropriate method.
