Shallal Rasas (水弾 Sharāru Rasāsu, "Water Bullet") is a magic tool used by Umm Madaura's Crew. It uses Water Magic that releases a blast of water shaped like a bullet, which is capable of blasting people several feet away. It can be hidden to look as if it is a sword.
This tool was later modified to create blades made out of water so Umm Madaura's crew of pirates could use the swordmanship they were taught by Sharrkan.
- The name of this tool is a corruption of the Arabic phrase رَصاص شلّال Raṣāṣ Shallāl, meaning "Waterfall Bullet".
