Square Kai — A Font Possessed by Shapes and Spirits 

Square Kai is a unique open-access typeface that fuses geometric minimalism with the mystique of Japanese folklore. Inspired by the yōkai — supernatural beings from Japanese mythology — and the purity of the square form, this font offers a dual-layered visual language. 

Uppercase letters are clean, modern characters grounded in square-based geometry — perfect for bold titles, posters, and digital works. 

Lowercase letters, on the other hand, transform into abstract yōkai-inspired masks — each glyph a miniature spirit, echoing centuries of myth through stylized forms. 

Ideal for designers, illustrators, and storytellers looking to add an eerie, mythological twist to their work, Square Kai blurs the boundary between typography and symbolism.
