Dragon Quest: The Adventure of Dai

Dragon Quest: Dai no Daibōken (Japanese: ドラゴンクエスト - ダイの大冒険 Hepburn: Doragon Kuesuto - Dai no Daibōken, lit. Dragon Quest - Dai's Great Adventure), is a Japanese manga based in the video game series Dragon Quest. It was originally created as a two-chapter short story titled "Derupa! Iruiru!". Its subsequent success led to the three-chapter sequel "Dai Bakuhatsu!!!" (Dai Explodes!!!), and later the serialization of Dai no Daibōken in Shueisha's Weekly Shōnen Jump.

The manga later spawned an anime series, which would be the second one based on the Dragon Quest franchise, Dragon Warrior: Legend of the Hero Abel (known in America simply as Dragon Warrior), being the first. Dragon Quest: Dai no Daibōken is one of the Weekly Shōnen Jump '​s best-selling manga series of all time, with roughly 40 million copies sold.
