Kusanagi is a dark cyberpunk theme inspired by Ghost in the Shell:
neon cyan and hot pink accents diving through a deep-space blue
background, with comments receding into the noise like static on
the net.

It is a proper derivative theme built on the Modus themes
infrastructure (version 5+), using `modus-vivendi' as its base
palette.  It therefore inherits the full face coverage of the
Modus themes while applying the Kusanagi palette on top.

Usage:

    (add-to-list 'custom-theme-load-path "/path/to/this/directory")
    (load-theme 'kusanagi t)
