Rukususu Rukususu is a non - playable Tarutaru character from " Final Fantasy XI " . She is minister of the Federation of Windurst ' s Rhinostery , an institution primarily concerned with the study and cultivation of plants . She is rarely seen at the ministry , however , as she spends most of her time investigating the fate of her mentor , former Rhinostery minister Iru - Kuiru . This leads her to some of Vana ' diel ' s most dangerous locales . Rukususu has a French accent and uses a small amount of French vocabulary . Story . Rukususu takes great interest in the unfinished research of Iru - Kuiru . He believed that the ancient Tarutaru had been led to Sarutabaruta not by a star , as legend told , but by another civilization . This unpopular hypothesis drew considerable ire and ultimately delivered him to a lonely death in a distant land . Rukususu therefore keeps the pursuit of her teacher ' s work to herself . With the resources of the Rhinostery at her disposal , Rukususu ventures north to the Beaucedine Glacier . Thirty years earlier , Iru - Kuiru had discovered something there that prompted him to abandon the Federation . Rukususu delves deep into the ruins of Fei ' Yin in an effort to retrace his steps . Eventually Rukususu obtains a strange artifact and delivers it to Kerutoto , one of her researchers back in Windurst . Kerutoto senses Iru - Kuiru ' s spirit through the relic and suggests that he is somewhere in Elshimo . Rukususu departs for the southern continent immediately . She succeeds in tracking Iru - Kuiru to the Temple of Uggalepih , where he had met his demise . Standing in the Tonberry - infested ruins the minister ponders her mentor ' s research and his reason for leading her to the site . Soon after an adventurer arrives from Windurst on a mission to bring Rukususu home . This person happens to carry the " Book of the Gods " , however , and inadvertently attracts the ghost of Grav ' iton . Grav ' iton introduces herself as a Kuluu and , having mistaken Rukususu for the Star Sibyl , wonders why her people ' s collaboration with Tarutaru has been forgotten . Rukususu learns that the Kuluu introduced her ancestors to Windurst and built the Horutoto Ruins to convert moonlight into energy . At their urging the first Star Sibyl had used Horutoto ' s power to ensnare Fenrir and forge a pact that guaranteed centuries of prosperity for her people . Rukususu reveals that she is not the Star Sibyl and Grav ' iton therefore questions the presence of the " Book of the Gods " , which the first Star Sibyl wrote for her successors . The tome had become blank , however , and had been given away by Optistery minister Tosuka - Porika . Grav ' iton offers to temporarily recharge the book so that the Tarutaru can relearn their forgotten history . Rukususu subsequently sends it back to Windurst with the adventurer so that it can be examined . She also gives instruction that Grav ' iton ' s revelations about the settling of Sarutabaruta remain secret . During this time Orastery minister Ajido - Marujido had been incarcerated as a result of unauthorized entrance into the Full Moon Fountain . Rukususu decides to contribute her enchanted Rhinostery ring to Doctor Shantotto ' s jailbreak plan . Although this defies the will of the Star Sibyl , Rukususu ' s sympathy for Apururu , the prisoner ' s sister , outweighs her legal concerns .
