KawaiiWorlds is a multi-world manager plugin for Paper Minecraft servers. It lets ops create, load, unload, delete, and teleport between multiple worlds via commands (/kw) or an in-game chest GUI. It supports several world types — normal, nether, end, flat, void, and skyblock — with a per-world settings panel for toggling game rules, PvP, difficulty, time, and weather. World configs (type, seed, auto-load) persist across restarts in a config.yml file.
