Okayama in spring---the Tenchi family is enjoying lazy days. One day, Tenchi tells everyone he has to leave to Tokyo for spiritual training. As soon as he gets to Tokyo, Tenchi and his grandfather have to perform a ritual for a temple (Shibuya Temmangu) they are staying at. During the ritual, four evil spirits appear and attack them. Tenchi is caught between a rock and a hard place but gets saved by six mysterious females who come from different dimensions to save him. The next day, Tenchi goes to school where a girl who sits next to him seems very interested in him.

Tenchi's new life in Tokyo begins. The exit of the dimensional tunnel that connect Okayama and Tokyo is on bottom of Tenchi's Futon. Ryoko and Ayeka jump out of the tunnel and fight in Tenchi's room in Tokyo. Tenchi gets hit on his classmate Sakuya. Tenchi takes Sakuya's hand and runs when Ryoko and Ayeka see them together. Tehy run to a near by Temple and there appears Ine, the God of Matchmaking. Ine tries to keep them together by tying them together by the red ribbon of destiny.

After Tenchi forbids Ryoko to use the dimensional tunnel, she compromises by watching Tenchi through Washu's invention "Hokoku-kun." But due to an error in her machine caused by the ghost, "Zumino Yoshiaki", in Aichi her machine malfunctions. It sends fake information like Sakuya napping on Tenchi's lap, and Tenchi wearing an elephant stuffed doll. An enraged Ryoko exclaims, "Nobody interferes with my long distance love with Tenchi!"

One Sunday, Sakuya and Tenchi go downtown. When they get away from the congestion and go into a back street, they find a mysterious house surrounded by fog. One of Yuugi's confidants, Hotsuma, was waiting inside. He tells them that the house is the "House of Vows" where if a couple makes a vow, they can receive eternal love. Tenchi and Sakuya are forced into a marriage by Hotsuma. Ryoko and Aeka rush through the dimensional tunnel to Tokyo. Will Ryoko and Aeka save Tenchi?

The Masaki family Budget is running out. When Ryoko, Aeka, Mihoshi, and Kiyone find that they cannot pay their new rent, they go to Tokyo to find jobs. But since they aren't used to working, they have a lot of trouble and end up getting fired. Kiyone and Mihoshi are classfied as "The gods of death" part time workers. Kiyone is shocked by their failure in Tokyo. But when they see a brochure that advertises "1,000,000 yen a day"... Is this help form above? Or is it a trap from below?

When Ryoko and the others try to get the money that Sasami and Ryoohki earned, she goes to Tenchi's place to hide. When Sasami decides that she will use the money she has to make them stop bothering her. Tenchi takes Sasami to Shibuya. Sasami wanders away from Tenchi and into one of the stores she finds. But the store is run by Yuugi. Yuugi approaches Sasami disguised as a young girl. After Sasami befriends Yuugi, they enter the dark world inside the mirror...

Today is the "Tenchi anniversary", exactly two years after Ryoko and Aeka met Tenchi. Aeka and Sasami prepare a great meal and wait for Tenchi to come back. Ryoko looks inside the lake; to the spaceship that sunk there and feels nostalgic. Ryoko and Washu escaped from Aeka and came to Earth. The chance that was made by Tenchi's necklace.

As everyone gathers in the house the Tenchi anniversary party begins. Everyone recalls the day when they met Tenchi. When Sakuya shows up, the happy atomosphere changes dramatically. As Ryoko and Aeka do not like Sakuya, they tease her quite a bit. After they find that they've all lost their gems, Ryoko's anger towards Sakuya explodes! Who stole their gems? The investigation beings!

While Tenchi is visiting ruins built more than 3500 years ago, he drops into an underground cavern with Amagaski and Umanosuke. As they look around they notice the lower ruins are larger than the surface ones. Then mysterious guardians show up and start attacking Tenchi. It seems that the Gaurdians are trying to force Tenchi into an empty stone crypt. What are these ruins really? Who was in the stone crypt?

Makeup on Ryoko's face? When people laugh and twitch in fear and disguist, Ryoko screams at them "What's wrong with me!" Around the same time, Tenchi starts thinking about Sakuya; as she started distancing herself from Tenchi. Sakuya also feels awkward getting close to Tenchi. One day, Tenchi finds two messages on his answering machine, both possible dates. One from Ryoko, the other from Sakuya, at same park near the station on Sunday! Tenchi is in the trouble! On Sunday, Tenchi is surprised by Ryoko looking unusually feminine. But in appearance only, she's still of her usual manners. They walk around the city, and when it gets dark Tenchi finds Ryoko's lip shine. At same time, Sasami and Ryoohki find a lipstick called "Night Pearl Rouge" in Ryoko's room. The reason that Ryoko's lips shine is because of the lipstick. Also, Tenchi sees Sakuya, who has been waiting for him in the park, She also has shining lips...

While Sasami is preparing dinner one evening Ryoohki appears in the kitchen to get some food. But when Sasami finds Ryoohki, she tells her to leave. At the same time, Ryoko and Aeka are fighting over a snack. They eventually break the figure of a golden Buddha, a figure that Katsuhito was keeping for his friend. Ryoko and Aeka are in trouble. Then they notice a hungry Ryoohki walking in, they decide to blame everything on Ryoohki. Ryoohki tries to prove her innocence, but nobody believes her, and her best friend, Sasami, also calls her a liar. Ryoohki, feeling hurt, decides to run away. Then she meets Kenoohki. The friendly Kenoohki flies together with her to the moon. Ryoohki finds there are many Ryoohkis living there. Meanwhile, Ryoko and Aeka start to feel guilty, but Ryoohki hasn't come back. They find that Ryoohki is on the moon. The whole Tenchi family flies to the moon in Mihoshi and Kiyone's patrol spaceship!

"This is the worst!" Masaki family's angry voice cuts the peaceful morning. Nobuyuki, is the only one that stands still in those angry voices. Since Sasami is sick, Nobuyuki is responsible for household chores. While Nobuyuki cleans up, and washes clothes, beside sleeping Ryoko, he runs away to Tokyo, to Tenchi's place saying "I wish I could be like a cloud they have freedom." Nobuyuki doesn't know that Tenchi and Sakuya are in awkward relationship; it was very awkward mood in Tenchi's room, Tenchi, Sakuya, and Nobuyuki. Nobuyuki walks outside to smoke. As Nobuyuki throws away the used cigarette, Matori turns the cigerett into "Oyajimodoki". Matori tries to get Tenchi and Sakuya together.

In Tokyo, Tenchi drops gems, and picks them up, the gems start to flash, the gems that Ryoko has also flashes!!

The TV is reporting about twin comets, but Aeka isn't interested, Her interest lies in the relationship between Tenchi and Sakuya, which seems unfocused because of Yuugi's attack. It seems like Aeka is the only one with any interest in the relationship. Aeka is very happy, but she finds that she has no money to get to Tokyo. Then Aeka sees a story about hitchhiking. Aeka makes Sasami and Ryoohki go with her to Tokyo, Yuugi and Tsugaru see them, and smile.

They try to convince Ryoko to stop, when it seems that they have succeeded, the Galaxy police service shows up at Ryoko's base.

Ryoko, feeling the fool, sneaks out in Gaien, her spaceship. But as she tries to fly away, she is caught in a trap that Hotsuma set, and explodes. In Tokyo, Tenchi sweeps the ground of Tsuchida Shrine, but it seems that he is unable to concentrate on his work. It's because he notices Sakuya's attitude is different. Tsuchida and Amagasaki, friends of Tenchi, come to the shrine to visit. He talks with them and finds that they don't know about Sakuya. Tenchi, surprised, checks his class namelist.
