• Portal — yes 'The Tale of Takeshi, the End-of-the-Century Leader!' is a Japanese manga series written and illustrated by Mitsutoshi Shimabukuro. It started in Shueisha's manga magazine Weekly Shōnen Jump in July 1997. It was suspended from the magazine in August 2002, following Shimabukuro's arrest for violating child prostitution laws. Its chapters were collected in 24 tankōbon volumes. The series briefly resumed in Shueisha's seinen manga magazine Super Jump in 2005, with the added subtitle Kanketsu-hen. In 2001, the series won the 46th Shogakukan Manga Award in the children's manga category.

From birth, Takeshi, a seven-year-old boy with a distinctly middle-aged appearance, was perceived as a natural leader. His first word was "leader", and his father, Hiroshi, was a quintessential leader among salarymen. Following Hiroshi's sudden death, Takeshi dedicates himself to emulating his father. He joins his first-grade class with the singular goal of becoming a true leader to his peers.
