Microscopic Scientific Ninja Tools

These are microscopic Scientific Ninja Tools developed by Amado which are integrated into an individual, allowing them to augment certain parts of their bodies as weapons.

The tools allow the user to create blades, shields and projectiles out of their own flesh. For Delta, she is capable of using her legs as jet propulsion. Also granted by the tools is to some degree, regeneration, should any transformed limbs be destroyed. According to Katasuke Tōno, this makes anyone possessing these tools as a "living Scientific Ninja Tool".

Trivia

 * The body augmentation granted by the tools strongly resembles Jūgo's clan's Sage Transformation. While the physical distinction is uncanny in the manga, how they are portrayed in the anime are different compared to the clan’s kekkei genkai.
 * In the anime, the transformed appendages show off a different coloured glow for each of the users; orange for Kawaki and pink for Delta.
