As part of theotaku discussion I'll be reviewing three anime, a spinoff, a reboot and a sequel, this is the spinoff Tenchi in Tokyo.

At the beginning, the female cast of Tenchi Universe crash land on Earth following an incident in which Ryoko and Washu steal a powerful crystal from Jurai in which Ayeka, Sasami and the Galaxy Police duo of Mihoshi and Kiyone pursue the space pirates. After getting stuck on Earth when an heirloom of Tenchi's defeats monster Ryoko, the regular Tenchi scenario begins, only two years later Tenchi moves to Tokyo to study being a Shinto priest. There he meets Sakuya who later would become his girlfriend making the girls back home jealous and suspicious. These suspicions are realized when a Juraian mutant named Yugi becomes fascinated with the power Tenchi possesses making his meeting with Sakuya all the more coincidental.
I applaud the removal of Tenchi's link to Jurai as it clears up so much baggage that the plot relies on to function but Jurai still has far too much influence on the plot as a whole and it still doesn't make for interesting villains.
Also for the first time since the movies has the plot of Tenchi being with a girl outside the six been explored longer and thankfully it doesn't make the regular cast unbearable especially Ryoko who really pushes the clingy jealous girl trope.
Finally there is different animation which feels less in quality but more expressive very much like the transition between Pokemon Kalos and Alola seasons.
The dub cast is the same as previous seasons so the quality is still very high.
To compare to previous seasons this is the best structured story but lacks the impact of the previous seasons even though they have way more flaws than the Tokyo series. I think it's because by time of release it already felt like Tenchi Muyo ended on the 3rd movie and anymore seasons of different retellings were starting to become stale which were already showing signs of in the Universe series. It's not a bad series just Tenchi Muyo passed it's sell by date.
Final Verdict: Tenchi in Tokyo is good but it had the unfortunate task of following two very successful seasons making this one stale before it even began.
