Ikenai! Runa Sensei

In 2014 a live-action version of the manga, starring Mikuru Uchino, Aimi Yoshikawa and Megu Fujiura, was produced by SPO Entertainment. Wataru's father leaves him alone but not without some guidance - in each episode he is visited by his teacher, Runa Sensei, who instructs him on various subjects - math, cooking, wrestling, acting - in a busty, and sexy way. Runa is played in each episode by a woman who bears a resemblance to a JAV star and she usually seems to end up losing her clothing while giving him lessons.
