I understand that you're weak, and I can see a future where you ally with me. Now, my treasured mallet! Impart the power of dreams to all the speechless tools!
~ Shinmyoumaru Sukuna

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.


Shinmyoumaru has short purple hair and brown eyes. She wears a pink kimono with a black obi and a frilled dress (probably petticoat) underneath. She has a black bowl with golden decorations as a hat. She holds a needle on her right hand, while the Lucky Mallet is being held on her left hand. Her height is short, since she is a Dwarf.


Shinmyoumaru acts and speaks as if she was a young child. Along the same lines, she appears easily persuaded, as she readily accepted the fabricated history of the inchlings that Seija Kijin fed to her.


  • Yatsunashi Tsukumo, Benben Tsukumo & Seija Kijin - they all share the same goal of overthrowing society


  • Shinmyoumaru is based on the One-Inch Boy.
  • Her first name, Shinmyoumaru (針妙丸(しんみょうまる)), means "cirling strange needle" and her last name, Sukuna (少名(すくな)) means "small being".
  • A silhouette of Shinmyoumaru appears on the front of Double Dealing Character's jewel case.
  • One of her spellcard in Double Dealing Character is Attack on Kobito, which is a reference to the anime series Attack on Titan.
  • Strangely during her second non spell card, she has the biggest life among all the bosses known. (Except for older game bosses.)
  • Shinmyoumaru is one of the only 2 final bosses that is a subordinate of an earlier boss (Seija), with the other being Utsuho.
