All the way to Kaioh's planet
The Snake Way is a narrow road of a million kilometers that connects Emma-Daioh's palace to Kaioh's planet. It's shaped like a snake, hence the name. Should you take a wrong step and fall over the edge, you land straight in hell with no way of turning back.
A truly extraordinary road!
