Koru - Moru Koru - Moru is a non - playable Tarutaru character in " Final Fantasy XI " . He is the principal and former minister of the Aurastery , the Federation of Windurst ' s introductory school of magic . He is well known for enchanting tiny dolls to perform useful functions such as tracking enemies or detecting pollutants . Although Tarutaru are known for their curious speech patterns , Koru - Moru ' s style in particular is notably similar to that of cartoon character . Koru - Moru ' s alter ego is a red mage and can cast spells such as Haste II , Refresh II and Phalanx II . Story . During the Crystal War , Koru - Moru continued the education of Windurst ' s children in spite of the encroaching Yagudo army . The difficulty of this task was compounded by one especially bright student , Ajido - Marujido , who abandoned his studies and eluded Koru - Moru in an effort to join combat . Eventually Koru - Moru enlisted the Mithra Mercenaries to keep his rebellious pupil in line . Some time later Koru - Moru was summoned to Jeuno as part of a research effort to alleviate the food shortage thrust upon Vana ' diel by the war . Having received a pair of bodyguards from Romaa Mihgo , he proceeded across the continent on foot . He forgot to bring his official papers , however , and was nearly turned away at Jeuno ' s gate . Fortunately Koru - Moru was spared a return trip when Rasusu , his colleague and girlfriend , emerged from the city to identify him . Koru - Moru and Rasusu took many walks together in the Ru ' Lude Gardens as they considered methods to avert the looming famine . It was on one such walk that Koru - Moru had the idea of using Windurst ' s sacred star trees for food . Rasusu dismissed the concept as the plants were not allowed outside Heaven ' s Tower and the consequences of a minister absconding with one would be severe . Even so , Koru - Moru could not bear to see Rasusu saddened by the hunger roaming the streets and covertly returned to Windurst to steal a bag of starseeds . Though Rasusu was flattered by this gesture , she begged Koru - Moru not to use the seeds for fear of what would be done to him . Instead she took the bag and embarked on an unspecified mission of her own . Rasusu promised that they would plant the starseeds together if her plan failed . She never returned , however , and Koru - Moru was recalled to Windurst before he could find her . Present Day . Koru - Moru resides in a manor in Windurst Walls and spends much of his time collecting curiosities from adventurers . Though officially retired for four years , he serves as principal of the Aurastery due to the disappearance of his successor , Minister Sedal - Godjal , three years earlier . Unfortunately he does not pursue his administrative duties as intensely as he once did and rarely leaves home . Koru - Moru sometimes receives love letters from a girl named Mojiji . Although he has never met her , he is so pleased by the attention that he sends gil in reply . He suspects that she might be trapped somewhere and is eager to learn her whereabouts . In the past Koru - Moru had constructed a talking doll , the Star Seeker , with the ability to find his enchanted ministry ring when he routinely misplaced it . The Aurastery later elects to use this device to track down Sedal - Godjal , who inherited the ring when he succeeded Koru - Moru . The subsequent hunt reveals that Koru - Moru had embezzled a large amount of gil in his time as minister and that Sedal - Godjal had invented " Mojiji " as a means of squeezing money back out of the professor . The Aurastery opts not to inform anyone of this and allows the ruse to continue . When the baby star trees at Heaven ' s Tower become unhealthy Koru - Moru is consulted alongside fellow retired ministers Yoran - Oran and Shantotto . Koru - Moru argues that the Federation has been using the same soil for hundreds of years and that its nutrient depletion is the obvious source of the problem . His colleagues have other ideas and their discussion quickly reaches an impasse . All three stubbornly implement their own solutions . The star trees fail to improve , however , and the professors decide to review past events to determine where the problem began . This line of thinking leads Koru - Moru to recall his time with Rasusu . Supposing that the trees might be holding a grudge over the stolen bag of starseeds that she carried , he quietly dispatches a mage to search for any trace of her . The seeds are eventually discovered in an elemental roaming the Crawlers ' Nest . When the bag is returned Koru - Moru learns that many other seeds had been destroyed by flooding during the war . No one , not even a spiteful tree , would have noticed they were missing if he hadn ' t mentioned it . Having discounted Koru - Moru ' s hypothesis , the professors consider the possibility that the trees are affected by a talking doll he had given to Shantotto during the war . He had designed this Foe Finder Mark I to detect enemy troop movements but Shantotto had abandoned it and heard it cursing all of Windurst as she left . When the remains of the doll are retrieved from Castle Zvahl Keep , however , it is determined that it is completely run down and could not influence the star trees . The retired ministers finally order Toraimarai Canal to be searched for evidence of trouble beneath Windurst itself . Koru - Moru rebuilds the Foe Finder as the Sluice Surveyor Mark I for this purpose . This provides proof that magical stagnation is accumulating in the canal and damaging the star trees above . The Sluice Surveyor also indicates an unusual presence in the Horutoto Ruins . Koru - Moru investigates this area and discovers a bud of the Great Star Tree , suggesting that the original tree is sufficiently aware of the threats against it to attempt a new beginning for itself . Although this is a great discovery for Windurst ' s ministries , Koru - Moru is crestfallen . He had imagined that Mojiji was waiting for him in the ruins .
