Mother Goose System

The Mother Goose System is a device made by Sorae Igarashi in order to seal the Wretched Egg. The MGS is positioned in the center of Deadman Wonderland.

Operation
The MGS is made out of two main parts: the Center Part and the Chorus Blocks. The Center Blocks are composed around the Center Part in the formation of a circle.

The Center Part transmits The Lullaby to the Wretched Egg, so its powers will be sealed. The Chorus Blocks enhance the Lullaby so it has a wider range. When Shiro can't hear the Lullaby anymore, the Red Man takes over. When the volume of the Center Part is put to maximum, the Wretched Egg is completely sealed.

To operate the system, a key is needed. Toto Sakigami, currently is control over the MGS, has tried many times to unlock the system, but constantly failed. Apparently, a certain kind of Brach of Sin is needed to unlock the system, one Toto doesn't have yet. This Branch of Sin is most certainly Ganta's Upgraded Ganta Gun.
