The 257th Element

A time not too far from now. To find a solution for the food problem caused by a growing population, every country has been investing huge budgets into scientific research to increase every single mass with as limited time and energy as possible. As a result, new elements the 119th and beyond were discovered and created one after another, and finally, a genius scientist in Tokyo named Hikojuro Araki succeeded in creating the 256th element, Araraginium, which is a dreamy element that creates every being out of nothingness.

However, at the very moment when the first experiment in the world to create Araraginium just began, by an unexpected accident, it diffused all over Tokyo and disappeared.
