How to use: First, insert the SD card into the slot on the sword. Then you can go to the official website to download new sound effects and dialog as you like. Every week there will be new content available. When using it with the DX Seiken SworDriver or other Emblems, just connect them properly. Attention: When handling the sword, be careful not to drop it to avoid damage. Also, make sure the SD card is inserted correctly to prevent data loss. Maintenance advice: Keep the sword in a dry and clean place. Wipe it gently with a soft cloth if it gets dirty. Don't expose it to direct sunlight for a long time as it may fade the paint.
