Kawahara Kaneichiro is the strongest exorcist alive, so business at his agency is booming and clients keep streaming in.
But after taking on one endless job after another, Kaneichiro grew tired of it all and gradually became worn out.
Kaneichiro had a wife through an arranged marriage, but because he was so busy with work, their life together after marriage was uneventful.
He thought his life would go on like that forever, but then the unexpected happened:
He and his wife both returned to their high school days.
Back in the past, Kaneichiro planned to give up exorcism and spend more time with his family, but...
His wife, Yukinoshita Yukino, was determined to take on the mission of defying her family, and her first goal was to oppose their arranged marriage.
Meanwhile, school beauty Asuna Yuuki confessed her feelings to Kaneichiro.
Before he could figure out what was going on, Kaneichiro also accepted a job tutoring a set of quintuplet sisters.
What will the future hold?
