Isutoshi (いすとし) is a Japanese manga artist, creator of erotic comic series Slut Girl and the non-erotic manga called Tende Freeze! (てんでフリーズ!). He started his career in 1994 producing work that would later be published in dōjinshi by the Gerumaru (ゲルマル) circle. His stories typically involve both erotic and humorous situations, focusing on characters' personality and sexual interaction during the story.
Isutoshi has produced a number of short works for hentai anthologies such as SNK Monogatari, Bruem - King of Fighters and Gensen Sexy Fighters, some of which were collected by Gerumaru in the Renge dōjinshi. Isutoshi has also produced short works published in the monthly hentai magazine Comic Kairakuten Beast.
Isutoshi wrote and illustrated the Japanese eroticmanga series Slut Girl (スラッと女, Suratto onna), which humorously focuses on the sex-driven relationship between the chief characters. 'It was first published in 1999 by Fujimi Shuppan. It was translated and published as a six issue series in the U.S. by Eros Comix in 2000. In May 2003 Kodansha released Slut Girl +α, a reprint with an extra chapter. Derek Guder gave the manga series a three-star review in Manga: The Complete Guide, praised for "distinctive" and "expressive" drawings, and the fact that not only are the manga's women well made, but also the recurrent humor: "The story lines are played up for comedic payoff, and you can't help but laugh at the characters' facial expressions liven up otherwise boring sex scenes."[1]Timothy Perper and Martha Cornog praise the expressive translation of the English edition, and describe Sayoko as a "tsuya/yoen" woman, a complex figure with "voluptuous charm" and "bewitching beauty". They describe the manga as being a satire on modern life, especially the role of women in the workplace, and a "long-enduring glass ceiling".[2]
