Story
Long ago, a legendary warrior and crown prince of the Juraian Empire, Yosho, disappeared and never to be heard again. Unknown to the Juraian Empire, Yosho never wanted to become a ruler and only wanted a quiet peaceful life; he settled on Earth. He discovered the Misaki Shrine and married the daughter of the Misaki priest, Itsuki Masaki; he would rename himself as Katsuhito Masaki. The two later had a daughter, Lady Achika Masaki, princess of Jurai. She would later marry her high school love, Nobuyuki, and the two had Tenchi. Unfortunately, Achika died from illness one snowy winter; Nobuyuki and Katsuhito helped raise Tenchi in the country side, near the Misaki Family Shrine. Tenchi's life was at first normal, but things quickly changed when intergalactic alien girls started coming into his life.
At 17, Tenchi's life was dramatically changed by the appearance of Space Pirate Ryoko. Evading the Galaxy Police (GXP), Ryoko was piloting her spaceship and cabbit, Ryo-Ohki, and battled with GXP officer Mihoshi when both crash-landed near Tenchi's home. Tenchi found an unconscious Ryoko and tended to her. When she awakened, she gave a fantastic story of how she's being pursued by a terrible space pirate, temporarily earning the Misaki family's trust and gaining their shelter. However, Ryoko's lies easily fell apart when it was discovered her pursuer was actually the GXP and Ryoko is the true pirate. Unfortunately, with Mihoshi's ship destroyed, it was pointless to arrest Ryoko; both girls stayed at the hospitality of the Misaki house.
Desiring to return home, Mihoshi activated an emergency beacon and it was detected by Juraian Princess Ayeka. When Ayeka arrived, she was shocked to find her old nemesis, Ryoko, was there. Starting a fight, the two battled each other by ship combat and both lost their ships in battle; Ayeka ended as the recent addition to the Misaki household, along with her robotic wooden guardians, Azaka and Kamidake. Not long, Ayeka's little sister, Princess Sasami, had arrived to rescue her sister.
It was around this time that Ryoko revealed that her ship can regenerate itself. In her cabbit form, Ryo-Ohki developed a great love for carrots and could not get enough of them. By the time Sasami arrived, both Ayeka and Ryoko developed romantic feelings for Tenchi. Reluctant to leave, it was time for everyone to part ways. Unfortunately, Sasami accidentally had a carrot with her and it attracted Ryo-Ohki. The cabbit could not resist the lure of the carrot and collided with each other's ships, causing everyone to be stranded on Earth.
The final two ladies to arrive would be legendary mad scientist Washu and Mihoshi's partner, Kiyone. Washu was imprisoned in a special crystal prison for her crimes of creating time-space devices with devastating effects upon the galaxy. Washu's crystal crash-landed in Japan and the inhabitants founded the Misaki Shrine to prevent people accessing the crystal, correctly assuming it is not a safe object. However, thanks to Ryoko's intervention, she was accidentally freed. She eventually set up two dimensional doorways within the Misaki house, one in a closet allowing her to cross dimensions between her lab and the Misaki family and the other in the bathroom creating a male and a female bathroom to allow privacy.
Lastly, Kiyone was sent to find Mihoshi. After finding her, the two were assigned to patrol and tour the Solar System; it is a severe downgrade. Both lived away from Tenchi's home and have their own place in the city, but due to Mihoshi's frequent blunders, making a living on Earth and balancing GXP duties was hard and Kiyone curses her fortunes because of it. Despite the occasional flares in battles between Ayeka and Ryoko, life was relatively alright until the Juraian military had come for the princesses.
Unknown to the princesses, the Juraian royal hierarchy of power was usurped by the sudden return of Yosho; it was actually Kagato in disguise. Yosho and Kagato both battled for the succession of Jurai in the past and Kagato lost. However, with Yosho conveniently missing, Kagato took his place as the long lost direct heir to the throne. Kagato then used his royal authority to have the military arrest and prosecute both princesses in an attempt to solidify his dominance in Jurai. The Juraian military arrived at the shrine and transported the house with everyone except Tenchi, Ryo-ohki, and Katsuhito into a battleship, seconds later, returning everyone except Ryoko and the princesses and shrinking the house and the robots into handheld sizes. However, they used Kiyone's cruiser and Ryo-ohki to free them and were on the run. Although not originally involved, the GXP was also under the influence of the Juraian Empire and Mihoshi managed to learn about the corrupted collusion between the GXP and Jurai; it made both Mihoshi and Kiyone fugitives. Framed for crimes of treason and terrorism against the crown, the whole group is on the run from the Juraian Empire and the GXP; they journey to Jurai in attempts to clear their names.
Being on the run was a difficult process. The group had to escape detection from local authorities on top of the GXP, but also make money in between to cover costs for food, fuel, and repairs to their ship. Washu was able to restore the robots to original size and operation as well as the house within the cargo hold of the ship, which served as the main area, excluding the cockpit, for the entire crew(same as it had on Earth). Things were often complicated due to Mihoshi's constant blundering nature as well as Ryoko's selfish nature. On top of that, Ryoko is also evading a long rival, Space Hunter Nagi, while committing major thefts to help sustain the group. However, the group managed to make it to the inner Juraian System.
Disguising their ship and themselves as a school group, the team had success infiltrating Juraian security thanks to Washu's anti-detection measures; it was once again fumbled by Mihoshi. Nearly unable to escape, the group was secretly aided by a loyalist to escape. While on their way to Jurai, Mihoshi's clumsy nature got them detected by a Jurian warship. However, Katsuhito instructed the crew how to escape capture: by entering a forbidden Juraian planet. Because it is a sacred place for Juraian royalty, their pursuers was forced to stand down until permitted entry. To take back Jurai, the team is going to need powerful warriors. Yosho decided to resurrect two legendary Juraian knights, the real bodies of Azaka and Kamidake, to aid in their quest. Although the Juraian knights have returned, their robotic counterparts were deactivated to bring them back. It was there that Katsuhito revealed himself as the true Yosho and the knights pledged loyalty to Yosho as their king.
It was at a Juraian villa that Yosho explained the nature of their enemy, Kagato, and his past. A rival and Juraian heir, Kagato became too obsessed with power and it caused him to abuse his Juraian powers. Yosho was forced to face his rival and defeated him in battle, but did not kill him. Kagato disappeared into the darkness and it was around the same time that Yosho decided to quietly settle down on Earth. Due to the shame and disgrace of Kagato's actions, the Juraian royalty erased the existence of Kagato, explaining why the princesses never heard about Kagato. However, Yosho's identity also pointed out that Tenchi is a direct heir to Jurai's crown.
On the eve before facing Kagato, both Tenchi and Ayeka was affected by recent news the most. Tenchi always saw himself as a normal high school boy, not heir to a major power in the galaxy; Ayeka was happy about it. She always knew her vacation on Earth would eventually end and she would have to bid farewell. However, with Tenchi as a direct heir, they can be together at each other's side for a long time, something Ryoko was not happy about. However, romantic intentions have to hold as Kagato appeared.
Kagato appeared for a private rematch with Yosho. Unfortunately, Kagato found a way to maintain his youth and also increased his powers; the aged Yosho lost the battle. Ryoko joined the battle, but was critically injured. Kagato then kidnaps Ayeka and flees. In critical condition, Yosho encouraged Tenchi to face his destiny with courage. Motivated to end the dark reign of Kagato, Tenchi and the royal knights journeyed to Jurai to face Kagato. Still injured from her fight, Ryoko pleaded with Tenchi to run away with her, but he was not swayed; Ryoko offered to take the trio to Jurai.
After Ryo-Ohki crash-landed on Jurai, Tenchi and his guardians stormed the palace. Kagato had his own dark royal knights and they tried to stop Tenchi, but Azaka and Kamidake defeated them both. In between, the rest of the girls managed to hold up the Jurian battle fleet by infecting their computers with a computer virus Washu created. Ryoko was severely injured helping Tenchi, losing a lot of blood, she lost consciousness due to her injuries and her fate is unknown. Now at the palace throne, Kagato fought against Tenchi. At first, Tenchi was losing, but the Juraian trees reacted to Tenchi and empowered him to rival Kagato. Theorizing Jurai itself has chosen its own master, Kagato angrily fought against Tenchi and lost; he admitted defeat and died and Tenchi saved Ayeka.
In the aftermath, there was a great media storm over past events. Everyone accused of crimes against the Juraian Empire has been exonerated. Yosho survived his ordeal and was happily treated by a group of pretty Juraian nurses. Ayeka decided not to punish anyone involved with Kagato, but the conspirators themselves quietly resigned to avoid retribution. Washu's involvement made her an honorary president of the Universal Science Academy and she vowed to use her skills for peace; barely a month later, she was ousted for developing a weapon that could destroy the whole universe. At the GXP, Kiyone got promoted to Detective Sergeant and Mihoshi was promoted to Chief Criminal Prevention Officer (albeit avoiding her responsibilities to hang with Kiyone). Azaka and Kamidake are no longer royal guardians, but chose to continue serving the princesses. Their robotic counterparts were resurrected thanks to Washu and return to Ayeka's side. However, Ryoko's fate remains unknown.
As for Tenchi, he has no interest in succeeding as Jurai's next ruler; he just wants to return to Earth and live a normal life. However, there was no mention of who would fill in the power vacuum. Tenchi resumes life back as it was, but finds it hard to adapt after living with so many girls; he misses them. Just as he thought of them, Ryoko appeared before him. She affectionately hugs him and declares that she intends to fairly win Tenchi's heart. It was also around this time that Washu decided to return to Earth. Kiyone and Mihoshi return to Earth as well, taking back their old apartment. Ayeka decides to run away and return to Tenchi's side; Sasami decides also to run off and the guardians join in as well. The story ends with all the girls coming back into his life once again.
