Created by Sensha Yoshida, and published in Shogakukan's "Big Comic Spirits" from 1989 to 1994. This manga is deemed to be one of the works that initiated the "irrational" or "unreasonable" gag comic genre, also known as non sequitur. One of the most popular characters that appeared in Utsurun Desu was "the otter", Kawauso-kun. Utsurun Desu. roughly means "it infects you" and is a homophone for a disposable camera produced by Fujifilm (where "Utsurun desu" means "it can take photos").
