It follows a boy, adept at martial arts, who escorts a princess on a journey back to her home country. Dragon Boy was well-received and evolved to become the serial Dragon Ball in 1984. But before that, The Adventure of Tongpoo was published in Weekly Shōnen Jumps 52nd issue of 1983 and also contained elements that would be included in Dragon Ball. Serialized in Weekly Shōnen Jump from 1984 to 1995 and having sold 159.5million tankōbon copies in Japan alone, Dragon Ball is Shueisha's second best-selling manga of all time. It began as an adventure/gag manga but later turned into a martial arts fighting series, considered by many to be the "most influential shōnen manga." Dragon Ball was one of the main reasons for the magazine's circulation hitting a record high of 6.53 million copies (1995). At the series' end, Toriyama said that he asked everyone involved to let him end the manga, so he could "take some new steps in life." During that near-11-year period, he produced 519 chapters that were collected into 42 volumes. Moreover, the success of the manga led to five anime adaptations, several animated movies, numerous video games, and mega-merchandising. Aside from its popularity in Japan, Dragon Ball was successful internationally as well, including Asia, Europe, and the Americas, with 250–300million copies of the manga sold worldwide. While Toriyama was serializing Dragon Ball weekly, he continued to create the occasional one-shot manga. In 1986, Mr. Ho was published in the 49th issue of Weekly Shōnen Jump. The following year saw publication of Young Master Ken'nosuke, which had a Japanese jidaigeki setting. Toriyama published two Weekly Shōnen Jump one-shots in 1988; The Elder and Little Mamejiro. Karamaru and the Perfect Day followed in issue #13 of 1989. Also during Dragon Balls serialization, Torishima recruited him to work as character designer for the 1986 role-playing video game Dragon Quest. The artist admitted he was pulled into it without even knowing what an RPG was and that it made his already busy schedule even more hectic, but he was happy to have been a part after enjoying the finished game. Toriyama has continued to work on every installment in the Dragon Quest series. He has also served as the character designer for the Super Famicom RPG Chrono Trigger (1995) and for the fighting games Tobal No. 1 (1996) and Tobal 2 (1997) for the PlayStation. The September 23,
