Tenchi goes undercover at an all-girls school to fix broken timelines, which means fifty episodes of him trying to be normal while surrounded by aliens, goddesses, and girls who have no idea what he actually is. The comedy lands because the show commits entirely to the absurdity, he's not playing a reluctant harem lead, he's a guy with a genuinely impossible job pretending to be a high school student. It's designed to be watched in short bursts, which is exactly how the best harem comedies work.

Tenchi goes undercover as a teacher at an all-girls school, sent to protect the world from the side effects of Washuu's latest experiments and restore balance to the timelines. He is pulled right away into a feud between the student council and the science club, and each side has a member who is central to his mission. Surviving the attention of the school's girls turns out to be a challenge of its own. This run of comedic sci-fi shorts with a harem flavor marks the franchise's 20th anniversary, and it is set in the city of Takahashi, which sponsors the show.
