Meigo Arisa

Meigo Arisa (鳴護 アリサ) is a level 0 esper. She is a singer who is aiming for a debut, and later, while performing in roadside concerts, wins an audition for the image song of the opening campaign for Endymion. She has a relation to a certain mystery, and according to Stiyl Magnus, could likely cause a war between the magic side and the science side.

Etymology
Arisa's family name can be translated as sound (鳴) and protect (護), a match for her singing skills.

Appearance
She has pink hair and pink eyes. She wears a loose smock-like light pink shirt, and blue pants. One of her most notable traits is that she is often seen wearing what seems to be a light blue newsboy hat with a dove on the left side.

Personality
Arisa is a very kind selfless girl. Like Index, she has a ravenous appetite. She is shown to be a hard worker, as she failed to have been an esper, she used the fact that she had nothing to work hard in order to become what she is today in hopes of achieving her dreams of being a professional singer. Yet she is somewhat haunted by the fact her singing sometimes follows disaster, although all people in those tragedies survive calling it a 'miracle'.

Background
Arisa was 'born' from Shutaura's prayer, in the form of her consciousness, on the Space Plane Orion she was on, as it malfunctioned and crashed down near Academy City. The only thing she has from the crash was a cracked blue bracelet.

She would later become her own entity, and make a name for herself as a singer on the streets. While aiming for a debut by performing in roadside concerts, she wins an audition for the image song of the opening campaign for Endymion.

Meigo chronologically first appears prior to the "Miracle of Endymion." She apparently meets Misaka Mikoto beforehand, and are apparently friendly with each other enough to have a nice chat.

Toaru Majutsu no Index Movie

 * Main article:Toaru Majutsu no Index Movie

Academy City's space elevator Endymion. One day as its completion nears, Kamijou Touma and Index Librorum Prohibitorum meets a Level 0 girl named Meigo Arisa, after hearing her busk it on the streets. They are enchanted by her singing, to which Touma assumes that she is a Telepath, while Index was surprised that she did not use any magic on it. Arisa tells Touma that being a Level 0 bothered her once, but now she is thankful for it, as because she had nothing else, that she could do whatever she could to be able to sing. She later says that she wants to sing in a large place with a lot of people. She dreams to be a songstress.

Arisa later gets a message that she has passed the audition, her song has been chosen to be the campaign song for Endymion. To celebrate this Index asks Touma to treat them dinner, but not before Touma gets a chance to hit some baseballs in a batting cage. After dinner Touma helps Arisa with her equipment and walk to a pond area. Here they are attacked by three witches. Touma and Index easily subdue them. Suddenly Stiyl appears, stepping in to fight Touma. The fight escalates to a point where Touma was about to be severly injured. But Arisa shouts trying to stop the fighting. This causes a 'miracle' as Stiyl's fires are put out and any debris that would have fallen on Touma did not. This knocks her unconcious as another fight takes place.

Afterwards she's taken back to Touma's apartment to recover. While unconcious she has a dream, she's amongst the passangers of the Orion space plane singing a tune holding a unique blue bracelet in one hand. She awakes from the shock of the dream where she is greeted by Index and Touma. Here she reveals that she might have an ability related to her singing. However, it seems to be connected with tragic happenings. But Touma and Index convince her otherwise, and await her public debut.

The next day Arisa meets up with Mikoto and her friends as they escort her to her audition. Here, they run across Ladylee whom Ruiko mistakes as a life-like doll.

Unknown to her a battle is taking place below the mall. Shutaura and a mysterious assailant fight to prevent the stranger's explosive threat. Touma comes to her aid and 'breaks' the assailant's arm, but he triggers the explosives causing the stage above to collapse. Kuroko assumes her Judgment duties and quickly teleports Uiharu and Ruiko out of harm's way while Mikoto protects Arisa and everyone else, which seems impossible at the moment. But the 'miracle' happens again leaving everyone unscathed by the fallen debris.

Sometime later, Arisa witnesses the events at the mall, a bit dizzy from talk of miracles. Touma finds her and urges her to continue on. So she does, continuing on with another public concert, and coming up with a new song with Index.

Later, Arisa and Index celebrate her upcoming performance at the Endymion Space Elevator at a local family diner. Unknown to them Marye, one of the magicians serving under Stiyl is disguised as one of the waitresses. Marye, along with her two partners kidnap Arisa and disable Index making a get away in a car with Stiyl. Shutaura and her forces give chase. Meanwhile, Touma, with Komoe's help track Arisa and Stiyl onto the highway. Stiyl manages to fend off all of Shutaura's men until she overturns the car, causing them to crash. Touma confronts Stiyl about Arisa. Stiyl, including Kaori believe Arisa's a Saint, and that there's something sinister at work linked to the story of the Tower of Babel, and her song would trigger something disasterous. But Shutaura is ordered to retrieve Arisa under Ladylee's orders and launchs a number of explosives at Stiyl and Touma. Touma is severely injured in the attack. Arisa is unconcious throughout these events.

Arisa is brought to Ladylee by Shutaura. Here Shutaura sees a fragment of a blue bracelet Arisa had on hand, the same fragment missing from her own bracelet and wonders how she got it. Ladylee reveals to Shutaura she's responsible for the events of the Orion Spaceplane engine blowout, costing the life of Shutaura's father. In anger Shutaura shoots Ladylee, but is still alive and can still stand. Shutaura is then apprehended by one of Ladylee's aids and is taken to a holding cell. Arisa is held captive in the highest place in Endymion. Ladylee explains her plans to Arisa about the part she will play in the destruction of the elevator, and the innocent people awaiting her performance. Arisa goes on with the performance while Touma, Index, Motoharu, Kaori, Stiyl and his disciples, Mikoto, her friends and the clones, and Accelerator and Last Order set out to prevent the elevator's destruction. The elevator becomes unstable, causing it to shake enough that the concert is cut short. The audience is terrified, but Arisa calms them with a song as they slowly evacuate out of the concert hall. Then Shutaura appears, and being angered by her singing, blows up the stage Arisa's on. Touma then jumps in and saves Arisa from the fall. Touma suffers from his back injuries during the fight, but manages to put everything together after playing Arisa's mysterious song, causing Shutaura to react negatively before 'breaking her illusion'. A fallen Shutaura quietly sings Arisa's mysterious song, the one she heard while on Orion, which led to the creation of Arisa. With the past resolved, Arisa and Shutaura are reunited, and their blue bracelets restored whole.

Abilities
She claims to be a Level 0, but she was shown to have stopped magic rubble and fire from hurting Touma with her voice alone, and it is referred to as a miracle.

Also, in the first chapter of the manga Toaru Majutsu no Index - Endymion no Kiseki (a manga adaptation of the movie), when a spaceplane called Orion makes an emergency landing and bursts into flames at the airport in academy city's 23rd district after its engine is damaged, all 88 people on the flight survive. The event is called a miracle and is described as possibly the most miraculous occurence in the history of flight. Meigo Arisa was a passenger on that flight and began singing when the disaster occurred. Presumably, Arisa's voice caused this miracle as well.

Motoharu Tsuchimikado suspects she's a Saint due to her unique ability to call upon a miracle. Fellow magician Kaori Kanzaki also believes it to be true as another Saint.

Later it is revealed that Arisa is an alter ego of created by the Saint Shutaura Sequenzia's wish to save the people from the spaceplane Orion.

Design evolution
Arisa's design was based around the concept of the elements. The bird motif on her hat represents a young bird watching an adult bird fly up into the sky from the ground. Her stage outfit is as showy as a bird-of-paradise or she growing wings.

Originally, her concert costume was based on real idols such as the AKB48, but because of time constraints he asked other illustrators and manga artists to aid him in the design as well as that of Ladylee's two attendants. The outfit that Arisa wears in the trailers and in the concert in the movie is the result of this collaboration.

Trivia
Although she was an 'alter ego' of Shutaura Sequenzia, Touma did suggest the she is a real human. This was supported by his reason that he had touch her with his right hand (implying his Imagine Breaker ability) proving that she is 'real'.
