The Beginning After the End is one of the most popular isekai stories ever made and features a blend of exciting action and thrilling adventure. The story follows Arthur, a king who is reincarnated as a child in a fantasy world, born to parents, Alice and Reynolds.
Since the first season of the anime just ended, many fans may be curious about whether Arthur's true identity is ever discovered by his parents. Yes, Arthur Leywin's parents do find out that their son is a reborn king, resulting in one of the most heartbreaking scenes in the entire story.
Arthur's identity in The Beginning After the End is a key part of his personality and development. As King Grey, the protagonist's life was devoid of joy, where he solely pursued strength and had no treasured relationship. However, after an untimely death, he was born again as the son of Alice and Reynolds in the magical continent of Dicathen.
Despite being reduced to a powerless child, Arthur found more happiness than ever, as he was surrounded by loved ones who showered him with care and affection. In his new surroundings, Arthur could pursue his passions freely and aspired to grow stronger to protect those near him.
However, holding so many people close also meant that Arthur's heart often took precedence over his mind. Ever since the beginning, the protagonist hated having to keep secrets from his parents, particularly his mother, who was always worried about him.
Arthur kept resisting the urge to spill the truth for a long time, but his emotions were in constant turmoil. Finally, after enemies from another continent whose powers far surpassed Dicathen were uncovered in The Beginning After the End, Arthur could no longer hold back his revelations.
When does Arthur reveal his true identity to his parents in The Beginning After the End?
Arthur reveals his true identity to Alice and Reynolds in chapter 148 of The Beginning After the End manhwa. After being saved from the corrupt Council of Dicathen by Windsom, Arthur came to understand the scale of his new world and the threat posed by the Vritra Clan, an enemy he would need to face soon to protect everyone.
Since he was not strong enough to achieve victory, he had to go to Epheotus to train with the Asuras. Right before leaving, Arthur had time to inform his family, who were being hidden by Rinia. At that point, wishing to put his heart to rest and not have any more clouded judgements, Arthur told his parents that he was a reborn individual who went by King Grey in his past life.

Though his parents initially thought he was joking, they didn't have a choice but to believe him after hearing how extensively detailed his accounts were. Unfortunately, this wasn't a heartwarming moment of acceptance but rather led to realistic and shocked reactions from his parents, who had been raising a middle-aged man as their son.
While Reynolds still tried adapting to the situation, Alice was devastated, even questioning whether their real son was taken over by King Grey. Nevertheless, after Arthur left to train, they tried consoling themselves by affirming that the 13 years they spent together with Arthur were real, and that they would try working through their issues gradually.
