Forgotten Conqueror got the true definition of true badass and ruthless protagonist. Spoiler: MC's Traits As a toddler, he obliterated the bandits who attacked the caravan he along with his parents traveled with. Before they attempted to beat and rape his mother who tightly embraced him, he bursted out his magic and popped their blood and organs inside out. The seven y/o boy, like a silent assassin in an open area, slayed a monster rampaging around the city plaza and saved, not only the people in the vicinity, but an old knight commander who put himself in danger following his duty. Rejected the proposal from a local lord regarding his daughter should be married off to him, for he didn't want to be "a shackle that chained her." He insisted to let her have liberty to select what she desired and enjoy the freedom to unwind the future what she deserved. The youngest person and the only commoner ever enrolled in a prestigious Zorin Academy for mages. Due to his appearance and status, most of the students sneered at him, but the quiet youth didn't care less of insignificant creatures who were irrelevant to his quest. A woman dubbed as "The Emerald Princess" and was the top of her class looked down upon the new transfer student. Filled with arrogance concerned to magic as she thought herself was the numero uno, she wanted to teach the boy a lesson. However, what happened later was not what she expected. In a mock battle, the unassuming boy's sheer power instantly crushed her and left the area like it was nothing. Curious about the youth's terrifying strength, the academy's headmaster decided to put him into a "test" of magic. Being the most high-ranking mage himself across the continent and only few on par with his level in the world, the headmaster and three of academy teachers ambushed the child with all his might, only to lost his left arm as the fearless boy retaliated. Then he was convinced that the small monster belonged to the lost rank which in this world only ever described in legends and myths. In an alley within one of the city's districts, a group of malicious boys were torturing a lone helpless little girl. A passerby child happened to stop by and noticed the scene which flared up his rage. He confronted and faught against the boys by making them felt what they did to the girl, healed the girl's wounds with his magic and brought her home safe. Responsible for the incident, the child was convicted, subjected to a trial and eventually won, but the father of one of the malicious boys, was not convinced and kept on lashing out against the stoic child ever since the beginning of the trial, for he wanted to see a solid proof. Irritated by the man's despotic personality, the child obliged and ripped off the stubburn man's entire arm in front of many people. An organization operating in the darkness wanted to recruit the indifferent young boy as they witnessed and became interested in his abilities. Upon his refusal, its members resorted to violent resistance, but they were treated like bugs as the cold-hearted demon incarnate fought back and flushed information out from them with force. He learned that their organization was responsible for chaos which had perversed the world many years. Merciless and unforgiving, he nfiltrated their base operation in the continent and massacred every member including their leader, and left only few who were later captured by the guild. A young woman described him as a coward upon seeing him didn't fought back against the sword training students who ganged up to him, despite her old knight grandfather's praises on him. She hadn't acknowledged that the boy didn't want to get involved with unnecessary conflict. Another young woman, on the other hand, became interested in him upon learning the boy's demeanor as he calmly rejected her lord father's proposal. Bookstore owners thought of him not a typical child as the boy obtained many various books from them. However, unknown to all, including his family, was what he actually possessed: unparalleled magic power, strength and ancient knowledge which cannot be attained in the current era, thereby placing him as being the most dangerous person in the world.
