I thought you'd be taller.Mikoto to the Warrior of Light
Mikoto is a Raen Au Ra with dark blue eyes, and blonde hair with light brown highlights.
She wears a sky pirate coat of casting dyed ice blue, republican halfgloves, a taffeta loincloth for the waist and legs dyed pure white, and Ghost Barque Shoes of Casting.
Mikoto is polite and intelligent, highly knowledgeable in Aetherology and geography. As she hails from Sharlayan, she is educated, and uses terms that may confuse others. At times she has to stop and think about explaining things, such as when she first describes the aetherial properties of the Otius she only receives blank stares and Cid nan Garlond requests her to try again.
Mikoto is brought onboard the Prima Vista by Cid to study the Auracite and understand its properties. Once the Warrior of Light and Lina Mewrilah board, Mikoto introduces herself as a member of House Jinba, a noble house in Doma, and a student from Sharlayan. After joking about the hero's height, she brings the Otius over to the group and begins to share her findings, although not knowing where to start Jenomis steps in and assists her. She explains the Otius is different from other crystals, as it not only absorbs elemental aether, but immaterial aether as well, such as thoughts, memories, feelings, and one's very will. Losing her audience, she explains the process is identical to summoning a primal, although the Auracite is its own source of power. During her research she concluded that Auracite was created by someone, and that the Otius was empty of Jenomis's aether, though it was in his possession the longest.
After the Warrior of Light helps the two moogles Hurdy and Montblanc, they return to find the band of bangaa brothers from the ruins of Lesalia at odds with Ramza bas Lexentale. The bangaa explain that their leader, Ba'Gamnan, has been acting strange and has gone missing, having come to the crew seeking assistance. They explain that Ba'Gamnan could have been transformed by the Auracite, and ask what his deepest desire is. The bangaa explain they were fusiliers in the Dalmascan army stationed at Nalbina Fortress thirty years ago. They were tasked with escorting Princess Ashelia to safety, but failed, and the group has felt shame about their failure ever since. Mikoto concludes the shame Ba'Gamnan feels has nourished the Duma, and that it has taken possession of him. Ramza begins arguing with Bwagi, but Jenomis finds something added to the final page of his journal: written in Dalmascan, "Ridorana". Mikoto tells of a place on the Valnard sea, far south of Rabanastre with a gaping maw known as the Ridorana Cataract, legends believing it the entrance to the Hell of water, and scholars descended into the chasm with none returning.
Following the demise of the transformed Ba'Gamnan, Ramza and the Warrior of Light return to the Prima Vista with a necklace identical to Ramza's mother, Tia. On the airship, Jenomis and Mikoto study the crystal as it previously left Ramza unconscious, but Montblanc tells them both necklaces are Auracite. Bwagi explains it was entrusted to Ba'Gamnan to return to Princess Ashelia. Ramza wakes from his rest acting strange, telling everyone the Auracites guide them to Ivalice, and that Ramza Beoulve wants them to uncover the truth of his homeland and the truth behind the origin of the kingdom. After touching the Otius once more, Ramza falls to the ground and returns to his usual self, leaving everyone confused at to what just transpired.
The Warrior of Light arrives on the Prima Vista earlier than expected in time to discuss the fruition of their previous discoveries. Their discussion leads on to Ramza Beoulve fighting against the unknown force known as Lucavi and Jenomis reveals the leader to be Ultima, the High Seraph. The Warrior of Light recounts his encounter with the Ultima spell in the Pratorium and Mikoto chimes in saying that the Ultima spell could be an Allagan interpretation of the High Seraphs magics. She tells the group that her colleagues all agree that the spell shouldn't be possible, but it would be if the Allagans learned it from a being not from this world. The group is interrupted by Cid arriving aboard the airship to deliver an item to Mikoto before leaving.
After the troupe is shown the location of the monastery, Alma enters the room once more. Her father and brother protest against Mikoto's idea to separate her from the Otius, and once the argument reaches a boiling point, it is revealed that Alma is being possessed by Ultima. In an attempt to break Ultima's sway on the girl, Mikoto readies her tool from Cid, only for Alma to be taken away through a portal. She hands over the small staff to the Warrior of Light and tells them that it should be able to match the Otius's power and disrupt Ultima's control, with a way to save Alma from the High Seraph's clutches the Airship departs to the Golmore Jungle.
With Ramza being taken instead of her sister, Mikoto blames herself for the staff being flawed. Fran cheers her up by saying it succeeded in shattering the Otius and saving Alma, Fran also wonders what Ultima meant by "blood of my invokers" possibly believing it to be Jenomis' ancestors. Jenomis Refutes this claim stating that Ultima was around long before Ivalician Legend. At that moment Alma's necklace begins to glow and the Warrior of Light receives an Echo flashback to the moment Orran Durrai tells Delita Heiral of Ramza's wish. The group realizes that Orran was the one to Erase Ramza's tale from history, and that Ultima actually wants Hydaelyn's chosen as her vessel.
With Ultima defeated and Ramza safe, everyone watches Ramza and Alma perform their final act of the Zodiac Brave Story. Sad that the adventure is over Mikoto tells the Warrior of Light that this has given the world's scholars much to consider and suggests that Sharlayan will have to open a school of Ivalician studies to keep up. She becomes inspired by the Warrior of Light and vows that she will put a request with the Students of Baldesion for an increase in Field research.
