Sensei is a four-issue limited series published by First Comics from March 1989 to August 1989.

The series follows Tadashi Natori, a person who feels that he was born in the wrong time.

Despite being born in the late twentieth century, Natori is trained in the ancient art of bushido, "the way of the warrior" that is the basis of the samurai lifestyle.

He spends his life yearning to live in ancient Japan where he thinks he would feel more comfortable and would have the opportunity to put hard-learned skills to use.

This, coupled with a lab accident back in his native time period, changes history and throws Natori into a barbaric New California in the year 2129.
