Rito and everyone decide to go to the old school building to find out if the rumor of a ghost haunting the building is true.

Lala and Rito are late for school, and Lala takes the opportunity to confess her feelings for him. They use a teleportation device to get to school faster, but they arrive sans clothing!

Everyone decides to have a fun afternoon together at the water park.  However, Rito now has a new source of relationship drama: Run has fallen in love with him, too.  Through their whole afternoon, she tries everything she can imagine to get Rito’s attention.  From fishing poles to vacuums and even fabric-eating fish, each of her attempts ends in disaster for Rito.  She finally gets some advice from Montemitsu and Rito’s teacher, but finds herself in a spot of trouble with the other patrons of the park.  Rito steps in to help her and Lala whips out one of her new inventions.  Unfortunately for Rito, this is only the beginning of Run’s campaign for his affection.

That Lala and her inventions. One of her crazy contraptions ends up getting Rito and Yami stuck to each other by their hands!

Rito, Haruna, and Lala are moving up in the universe, when an alien prince visits and they each become Ambassadors of Peace from the Earth.  They get more than just their titles, but a challenge to compete for the title of Greatest Hunter in the Universe.  This could be a big opportunity for Rito in reaching his goal of become the greatest man, so they compete.  After an adventure filled with dinosaurs and giant gorillas, Haruna wins the title, while Rito finds a group of Amazons who want to all marry him. 

Rito dodges potential encounters with women--and all their respective parts!--but he soon gets a firsthand look at the female anatomy...and not in the good way!

Rito is training hard to hopefully become the Greatest Man in the Universe and save his life in the process.  While out running, he bumps into Haruna walking her dog.  She becomes very supportive of Rito, even meeting up with him everyday as he runs.  Finally, Haruna asks Rito to have lunch with her by the river.  During their date, her dog falls into the water and is rescued by Rito.  Dripping wet, Haruna takes him to her house to dry his clothes.  There, Haruna trips and almost kisses a towel-clad Rito just as her sister enters the room.

Yuki wakes up to Haruna and Lala yelling at him that he is about to miss the ship. Lala decides she can't marry unless he wants too.

Rito is about to have the worse ‘meet the parent’ experience in the whole universe! Lala’s father, King Deviluke is coming to earth to see if Rito is worthy of being his daughter’s future husband and eventual ruler of their planet.  At school, Rito meets a strange girl on the roof, who turns out to be Lala’s father testing him.  Having made a very bad first impression, it looks like Rito is about to learn about intergalactic pain, until Lala steps in.  Now, Rito is left with only one option to save himself and the earth from total destruction: become the Greatest Man in the Universe.  

Lala vows to help Haruna find love. Saruyama points out that Rito has changed since became close with Lala. An outing goes horribly wrong, and Rito chooses to give his own life for Lala and Haruna. During this time, he realizes that he loves Lala. Rito...

The athletic festival has arrived and Rito is in the lead to making a complete fool of himself.  He’s trying everything he can think of to impress Haruna, but keeps accidentally bumping and touching her.  While Rito is pretty sure that Haruna absolutely hates him, Lala finds herself in competition with Saki, who still wants to beat her.  The only person who seems to be really enjoying themselves it the principal as he watches the female students go through bizarre and perverted contests.  

Celine is drunk and spreads her pollen, making Saki and the others fall for Rito. Rito sets out to buy groceries and runs into Misa. After she takes him around town, he ends up not accomplishing any tasks. Momo mistakes an innocent message for somethin...
