The ending of The World Only God Knows may vary in different versions and websites, but I can tell you a more common ending: At the end of the manga, the protagonist, Kuromu Kaito, lost everything he once owned, including his family, friends, and identity, and was forced to survive in a world full of mysterious powers and dangers. He met a mysterious girl who called herself the Apostle of God and told him that he was the only one who could save the world. The Apostle of God brought Hei Yu Kuaidou to a place called the "God's Domain". This was a world completely controlled by God, and only true believers could enter. In this domain, Kurou Kaito encountered many powerful gods and mysterious existences. He needed to use his skills and wisdom to survive. In the end, Kurou Kaito became an Apostle of God and led a group of like-minded people to save the world. However, before he could succeed, he had to face many powerful enemies and challenges, including those who wanted to stop him. This ending was rather tragic, but it could also be seen as the process of Hei Yu Kaito growing and becoming stronger. At the same time, it also expressed his thoughts and reflections on human nature.
