Shaorune

Shaorune (シヤオルーソ) is the Sacred Beast of Water in Tales of Rebirth. He is a large blue beast, commonly referred to as the "Great Blue Beast", and is similar in appearance to a Chinese dragon. Unlike the other Sacred Beasts, Shaorune accompanies the group and serves as their primary means of transportation later in the story.

Past
Shaorune is one of the six Sacred Beasts, known as the "Six Saints", who served the Sacred Beast King, Geyorkias, long before the events of the story. Each Sacred Beast possesses an arcane power—Shaorune's being Water. At some point in the past, the King and his Six Saints came into conflict over opposing ideals: Geyorkias believed they should eradicate all Huma from the world so that the racism and hatred between them and their fellow race, the Gajuma, would cease, as Huma had undergone a marked cultural development and waged war against the Gajuma in an attempt to subject them to the Huma's rule.

The Six Saints disagreed with this, believing the relationship between Huma and Gajuma to merely be the "workings of nature", and a battle between the two great forces ensued—the battle's outcome having the potential to affect the entire world. The people feared this outcome and struggled to fashion a model society at a time when vice and virtue were virtually nonexistent. After a battle that raged seemingly with no end, the Six Saints overcame Geyorkias and sealed him away, allowing Huma to continue existing in the world with the Gajuma. However, this battle also left the earth impoverished, and the Six Saints weakened as a result, leaving no one to guide the Huma and Gajuma, so the hatred between them—known as the "impression"—incessantly built.

Tales of Rebirth
Shaorune first communicates with the group through Mao, speaking through his body in Wontiga's shrine. He quickly introduces himself before warning Veigue Lungberg that he must go to Belsas immediately, else he lose something precious to him. Unlike the other Sacred Beasts, the group quickly senses Shaorune's light-hearted voice that resonates with joy and sincerity. After the events at Belsas, Shaorune speaks through Mao again, instructing the group to meet him in Babilograd if they wish to purify the impression currently tainting the world and its peoples' emotions. When the group arrives in Babilograd and enters its holy temple, known as the Shrine of Blue, Shaorune speaks to them, telling Veigue that he must pass three trials in order to obtain his power. The first trial Shaorune issues is that Veigue and his companions come to him, so the group ventures further into the shrine, allowing Veigue's hallucinations to begin.

In a flashback, Veigue is back in Sulz with Claire Bennett, who gives him a stone as a birthday present. Although the memory is genuine, "Claire" then claims she is Agarte Lindblum, who is currently occupying Claire's body at this point in the story. Veigue's frustration persists as the flashbacks begin distorting his memories and conflicting the personas of Claire and Agarte. Veigue begins questioning who is Claire and who is Agarte, even interrogating Claire, who is with the group, albeit in Agarte's body. In the final room of the shrine, Shaorune appears and introduces himself before informing Veigue that his first trial has come to an end. He then states that the second trial is to best him in combat, and the group engages with him in battle. After the battle, Shaorune states that the second trial has come to an end. For the third trial, Shaorune asks Veigue privately who the woman standing next to him is, and Veigue quickly answers that she is Claire. With this, Shaorune states that the third trial is over, wanting only an answer spoken with determination.

Shaorune then bestows his power of Water to Veigue and provides Hilda Rhambling with a clue in finding the next Sacred Beast. To the surprise of the group, Shaorune states that he will meet them outside and serve as their "wings" because he likes people and wishes to accompany them. When the group manages to obtain the power of all the Sacred Beasts, Shaorune leaves the group in an effort to not interfere with the mortal world any further. However, as conflict between Huma and Gajuma intensifies throughout the world, Shaorune rejoins the group, carrying them from city to city in an effort to settle the disputes that have emerged in the impression's aftermath. Shaorune later witnesses the destruction of Razilda with the group and serves as their transportation to Yuris's Realm, where they manage to defeat Yuris and save the world from destruction. At the end of the story, Shaorune joins Geyorkias and the other Sacred Beasts in bidding farewell to the group.
