It all began with a boy born powerless. He was born into a family with the best elements of Light and Magma. His family gave him the name Hantengu. All of Hantengu's brothers and sisters didn't like him because he was the weakest of them all, and born without powers. They would always make fun of him and sometimes even beat him. But he didin't care alot about what they did and focused more on his studies which were about how powers work, their foundation, strengths and their weaknesses. It turned out that every element's weakness is the villainous element, DARKNESS.
He was happy that he found a solution after years of intense studying and researching, but never knew how to obtain the dark element. Because no-one knew how to obtain it in this generation. The darkness element was the most powerful element of ancient times and so powerful that the 10 most powerful sages forbade the usage of the darkness element 100 years ago. The sages did their best to seal and hide any traces of this power and its history. At the age of 12 Hantengu went to the school's libary and went to look for a book of powers but instead found The Book Of Prophecies hidden behind a book with a secret lock behind it. After reading it Hantengu realized that this is the book he has been searching for this whole time. He opend it and a letter fell out of the the book which said ''There will be a kid born into a family of the strongest elements, with a pure heart, who will obtain the deepest powers of darkness elements and therefore he will begin his quest for anwsers''.
Hantengu was shocked after reading the letter from the book of prophecies and felt deep within his heart that the prophecy was true. He decided to study the book intensly in hope of being the chosen one mention within the prophecy. He told no-one about it and kept quiet while after 3 months, he started to learn the villainous power ''Dark''. 3 years of time passed and Hantengu still couldin't use the power of darkness since the fundamental power one must obtain to be able to use the power was hidden in secret cave. He was now 15 years old and descided to leave the town in search of the secret cave. He was about to give up when he stumbled across a map and a note under a large tree 10 miles to the south as written in the book of prophecies. He was confused why they were on the ground so Hantengu picked it up and read the note it said ''He who tries to find the power held by Shigaraki the strongest user of dark will be lead to the cave and after gaining the power, becoming his successor''.
Hantengu was happy of the thought of him being the successor of the power he dreamt and worked hard for. Weeks later into the journey he realized that the cave wasn't that far, it was right up ahead behind the hill with a rock that looks like an eagle. So he followed the trails on the ground and on the map. And luckily found the place it was in a black cave it had the dark element logo on it. So Hantengu entered the cave and when he walked a few meters he saw the cloak and the dark element floating so he ran and took the cloak on and touched the dark power and transformed into a dark user he had a special sword come with it. Now he has been given the nickname Vilios.
It translates to the word Shadow. Hantengu's eyes turned black and purple his hate for his family and anger took over him. He flew with his dark powers to the town and the people weren't ready for it. The first thing Hantengu did was destroy the places and the schools that made fun of him. He then went to the castle of Kings to his brothers and sisters and parents. They all went full power but they had no chance Hantengu absorbed every blow his family tried to land at him. Soon, due to the power controlling his senses this time, he ended up almost killing everyone. He pulled out his sword and destroyed one third of the hole country Sangawa with his strongest abillity Sacred Darkness. He then met Shigaraki the main user of Dark. And Shigaraki gave Hantengu an applause.
Hantengu was a bit sad his family got injured so bad even though one may argue that they deserve it due to treating him bad and tormenting for all these years. Out of shame, he went on without looking back, at least for now. Shigaraki and Hantengu teleported to the town of darkness users and Hantengu became the King of his generation. But... There were other strong foes watching Hantengu and are on their way to Hantengu's town NightGuard.
