The city of Tokyo is always lively and bustling, but underneath that flashy shell is a reality full of sin and injustice. Amid the skyscrapers and bustling crowds, Aiden lives the life of an ordinary person, but inside him is something special—a power he never dares to show. People with abilities like him, called "Anothers", make up only a very small part of society, but are the focus of all government anxiety and control.

The government has issued many strict laws to control capable people, making them live in darkness. The government, although built on good ideals, is rotting from the inside. Those in power only care about power and personal gain, abandoning the people they are supposed to protect.

Every day that passes, Aiden feels his difference as a burden. He goes to school with two friends, Akira and Aoi, his two closest friends, Akira is his childhood friend and Aoi is a friend from the same club, all three of them love and support each other very much, but he also not share with them his biggest secret. He didn't want them to be targets, he didn't want to be seen as a threat.

Aiden, is a boy with a warm and devoted personality. He is always the first to lend a helping hand to anyone in need. In the past, Aiden had a happy family. But in one afternoon, everything changed, a sudden attack from the government against capable people took the lives of his parents, along with the unborn baby brother that he lived with every daythat he hope to play with him everyday. The pain of this loss was deeply imprinted in Aiden's mind, causing him to live in fear and loneliness.
