Since the uncrowned event and the virus outbreak in 2019, the world has been very strained and trust between nations has diminished in the following years and to the present day.  We follow Shiki, a 23 year-old man, who during that time successfully fended of the Demon king's army, Duke of the Void, and a R.E.D from attacking the Central Empire all by his own. His memories became distant and fuzzy during that year, only seeing the silhouettes of the past. He yearns to remember his lost memories. In hopes of not losing himself from the shackles of the world.  He meets with an old friend whom at first encounter, didn't even knock the door.  "I don't even remember the time of my sister's birth, my own childhood, even my father's death. I don't even know If he was a good father or not."                                              - Shiki L. Rain
