• Portal — yes Masuda Kōsuke Gekijō: Gag Manga Biyori, or simply known as Gag Manga Biyori, is a Japanese manga series written and illustrated by Kosuke Masuda (manga artist). The series features a hyperactive, random, and nonsensical style that revolves around various plots and characters throughout. It started in Shueisha's shōnen manga magazine Monthly Shōnen Jump in the January 2000 issue. The magazine ceased publication in June 2007, and the series was transferred to the then-brand new magazine Jump Square in November of the same year, where it was published until November 2014. Shueisha collected its chapters in fifteen tankōbon volumes. The manga continued in Jump Square, under the title Gag Manga Biyori GB, in December 2014. Its first anime adaptation was a short film animated by Toei as part of Jump Festa in 2002. The first anime television series adaptation and the sequel were produced by Artland, while the third, fourth and fifth sequel were produced by Studio Deen. Most episodes are five minutes long. The first four series aired in 2005, 2006, 2008, and 2010, and the fifth series aired in 2025.
