Shinmyoumaru Sukuna is a Touhou Project character who debuted as the final boss of Double Dealing Character. She is an inchling living in the Shining Needle Castle. As an inchling, she is able to use the Lucky Mallet, the inchlings' most sacred treasures capable of granting wishes and mostly used for size-changing. She wanted to give weapons and inanimate objects the ability to express themselves, so she used the power of the Lucky Mallet to do so. Her wish was granted, but it came with the unfortunate side-effect of giving unimaginable power to the youkai. This was the cause of the Youkai Rebellion. She later appeared as a playable character in Urban Legend in Limbo.
