The Rukia is a customizable keyboard designed for enthusiasts, featuring two special versions: a personal "end game" model and a themed limited edition inspired by space opera. Priced at $390, it includes a per-key RGB USB-C PCB with underglow, accommodating both regular switches and rotary encoders in a designated key cluster. The keyboard's construction includes a sandblasted brass weight and new carbon fiber plates designed for improved sound and flex. It comes with a PC top and bottom case, screws, and one rotary encoder knob, with options to purchase additional encoders. The design emphasizes accessibility, allowing for unlimited orders to avoid competition among buyers.
