Rikku

Rikku is an Al Bhed girl who is a playable character in both Final Fantasy X and its direct sequel Final Fantasy X-2. She is Yuna's cousin. Rikku's father is named Cid, and she has a brother named (aptly) Brother. Her mother died before the events of FFX.

Final Fantasy X
After Tidus gets trapped near Anima's Shrine, in the ruins, he is 'rescued' by a group of Al Bhed. The main person (and the only one who can talk both Al Bhed and English) is Rikku.

She then joins Tidus in reactivating a underwater power plant, in which the Al Bhed then find an airship. She then promises to take Tidus to Luca she that he can try and find someone he knows. However, she is split apart from him when he is washed onto Besaid Island by Sin.

She is then mentioned again in Luca, when a group of Al Bhed kidnap Yuna. Tidus thinks the Al Bhed ship which Yuna is being held on is the same one as the one which Rikku was on, but it turns out that it isn't.

She is then encountered when the group is crossing the Moonflow. She pretends to be a robot in hopes of stealing Yuna and stopping her pilgramige. However, she is beaten by Tidus and Wakka, and is washed ashore. She is then found by the group, and becomes Yuna's guardian.

At Guadosalam, she then teaches Tidus about creating better weapons by fusing them with items. She then plays little role till the group reaches the Farplane, where she stays with Auron when the group enters the Farplane, claiming that the past is better left only rather then dewelled upon.

When the group reaches the Thunder Plains, it is revealed that Rikku is scared of thunder, and she cowers over most of the plains, only becoming happy again once the group reach Macalania.

She is then discovered to be Al Bhed by the rest of the group (as only Tidus, Yuna, Auron and Rikku herself knew that she was Al Bhed) when the group are attacked by Brother and a group of Al Bhed to kidnap Yuna. Tidus would then either ride with her or Lulu to Macalania Temple. If Tidus rode with Rikku, she accidently reveals that Yuna will die if she continues her pilgrimage, but Tidus doesn't relize.

She doesn't make much of an appearance again till Bikanel Island, where she leds the party to Home, only to find that it has been attacked by the Guado, and her friends have been killed. She then helps the group reach Cid, her father, who takes them on his airship. She also reveals that Yuna is going to die.

At Bevelle, she unleashes a light bomb to blind Seymour, so the group can get to Bevelle Temple. She then warns Tidus not to leave the fayth with Yuna and Auron, but the two decide to not listen, and exit the room and get kidnapped.

She then helps Tidus and Wakka escape from Bevelle, defeating Evrae for a second time.

She then makes partically no appearances to help the storyline till the group reaches the optional Chamber of the Stolen Fayth, where she moans that the cave is the scary most of the way.

Final Fantasy X-2
Two years have passed since the events of Final Fantasy X. Rikku and her brother, Brother, have set up the Gullwings Sphere Hunters group, with the help of Brother's friends Buddy and Shinra.

While searching for spheres, the group finds one with a person who looks like Tidus in it. She rushes to Besaid, where she shows the sphere to Yuna. Yuna then decides to join the Gullwings.

On one trip, Yuna's Garment Grid is stolen though, and Rikku and Paine infiltrate the thief's concert. The thief has dressed up as Yuna, and after a chase, the thief turns out to be Leblanc, head of the Leblanc Syndicate. With Yuna joining them, they manage to defeat Leblanc and her two sidekicks, Logos and Ormi, and get back Yuna's grid.

As chapter 1 draws to a close, the group has got spheres from Besaid and Zanarkand. They then hear news of a 'super' sphere at Kilika, so they head over there are steal the sphere. The sphere is of a massive machina named Vegnagun, and the person who looks like Tidus. The Tidus look-a-like talks about someone called Lenne, which sends Yuna into a mad craze. The group then decide to give the sphere to either the Youth League or New Yevon, which the player decides.

At the end of Chapter 2, the group heads off to destory Vegnagun, which lies under Bevelle. They enter the Fayth Chamber, only to find a massive hole. After jumping down, and following the long paths, they are met by Baralai, who leads New Yevon. The battle with Baralai will happen regardless of who the player gave the sphere to. The group beats him, and then find that Vegnagun has disappeared from it's chamber, leaving a lot of pyreflies and a dark Bahamut.

As Chapter 3 ends, the group has beaten a dark version of Valefor and Ifrit, both of which appeared at Besaid and Kilika. The group then heads to Djose Temple, where they beat a Dark Ixion. Dark Ixion survives, and knocks Yuna down the hole in Djose's Fayth Chamber. Rikku and Paine return to the airship and struggle to find Yuna, but eventually find her.

Chapter 4 ends with a concert, in which Shinra has created a sphere so that she can be seen anywhere across the Thunder Plain. Yuna wears her songstress dressphere, but it reacts with Shinra's sphere, and everyone sees the tragic end to Shuyin and Lenne. Shinra then reveals that the songstress dressphere gets it's power from Lenne.

As Chapter 5 draws to a close, the group defeats Vegnagun and Shuyin, and then they cross the Farplane, where they encounter the fayth of Bahamut, who grants Yuna the wish that she can see Tidus again.
