Cherry Global is another amazing theme. It draws inspiration from the Honkai Impact 3 game, the spiritual successor to Houkai Gakuen 2, using many characters from the previous title in a separate story.
This theme consist of several components including: aurorae themes (regular, solid, square, square-solid), konsole and kitty colorscheme, kvantum theme (regular, solid), plasma colorscheme, plasma desktop theme, and a splash screen

15. Sweet Mars KDE
Sweet Mars KDE is a dark and modern theme that’s superbly vibrant. It ships some of the most sublime icons you’ll ever see.
It’s published under the GNU General Public License v3.0.
Dracula is a dark theme using the Dracula colour palette. Besides KDE, it’s a dark theme for more than 250 different apps.
Arguably Dracula should be rated much higher. We love it!
Do you hanker after the appearance of the GNOME Shell but in all other respects you’re committed to KDE? Maybe KShell might be your Plasma theme as it seeks inspiration from GNOME Shell.
Numix is another quality Plasma theme featuring a flat, dark and sleek design.
