The effect of Hibana's Worm Eater on Owl's Eyeball.
Worm Eater is a device that instantly oxidizes the Nameless Worm that resides in a Branch of Sin. With the Nameless Worm gone, the Deadmen's blood becomes useless.
The Worm Eater being used by the Undertakers.
The Worm Eater was invented by Tsunenaga Tamaki and was given to the Undertakers. After Scar Chain's prison break, Karako Koshio smuggled Undertakers' weapons out of the prison and handed them over to Ekō Kaidō, in cooperation with Makina. He had a university lab research the Worm Eater and later planted it in a sword that was then smuggled into Deadman Wonderland. The sword was given to Makina who used it as a weapon against the Forgeries.
The Worm Eater has been effective against every Branch of Sin, except evolved variants like Ganta's Ganbare Gun and the Wretched Egg's Branch of Sin.
The only way to get around the Worm Eater, is to attack with the speed of sound, breaking the sound barrier or destroying it with physical force. Known Branches of Sin that can do this are Senji's Invisible Black and Ganta's Supersonic Ganta Gun.
