Studio ZiZ a year later announced its next project - it was the hentai anime "Tsuma Netori 3" spin-off "Zoku Tsuma Netori Ikumi to Shizuka Episode 1" based on the visual novel of the same name. The action of the plot still revolves around a pervert named Shiro Anno, who loves sex training, imprisonment and violence against innocent girls. The plot is not particularly new, and in fact it is all the same dissolute "adventures" of young and very sexy teachers Ikumi Sunohara and Makoto Kano.
