===Involvement with ''Dragon Quest: The Adventure of Dai''===
In 1989 Torishima planned to have a one-shot manga based on the series be featured in an issue of Jump as part of a promotional campaign<ref>『週刊少年ジャンプ秘録!! ファミコン神拳!!!』76-79頁</ref>. Horii disapproved of the idea, however, stating that it would be boring to create a manga based on the specific games because the fans would already know how the story would unfold. Considering this, Torishima instead proposed an original manga that was based on the worldview and themes of ''Dragon Quest'' instead of the individual games. Horii approved of this approach and Torishima hand-picked Riku Sanjo to write the one-shot due to his experience as a writer for Jump's video game articles in the late 80's and Sanjo's friendship with Horii insuring familiarity with the source material. Jump artist Koji Inada was approached to illustrate the project, but was initially hesitant as he wanted to work on a wholly original manga instead of a derivative work. Torishima was able to convince him otherwise however, and the trio began the planning phase of what would be titled ''Derupa! Iruriru!''. 

The two chapter one-shot proved to be a tremendous success, so much so that a three chapter sequel titled ''Dai Bakuhatsu!!'' was quickly approved. The follow up garnered an ever greater reception amongst readers and full blown serialization would commence within the same year, with the manga officially being titled ''[[Dragon Quest: The Adventure of Dai]]''. Torishima would withdraw from the project once seralization began, leaving it in the hands of his junior editors.
