Astral is a Duelist of another universe who can only been seen by [[Yuma Tsukumo]] and those connected with the [[Barian World]]; he can also be seen by people exposed to energy derived from the [[Astral World]] or Barian World, which included the [[Arclight Family]]'s power of the [[crest]]. Others cannot see or hear him, which often leads them to think Yuma is talking alone. Astral is not a physical being, but is shown to be able to hold Duel Monster cards, though it is unknown if it's only the "Numbers" or any cards. However, Astral can be seen through photographs, although he only appears as a light blue haze.<ref name="ep36">{{Episode|Yu-Gi-Oh! ZEXAL|36|ref}}</ref> He is also capable of flight as he is always seen floating, and seems to not rely on things such as food to live. Although, Astral needs his current partner to have "Numbers" and will start dying if those "Numbers" are forcefully taken away or when Yuma is losing life points in a Duel with an opponent that has a "Number".<ref name="ep6">{{episode|Yu-Gi-Oh! ZEXAL|6|ref}}</ref> Astral can only experience the sensation of taste when he and Yuma share a body in [[ZEXAL (power)|ZEXAL]] mode.<ref name="ep67">{{episode|Yu-Gi-Oh! ZEXAL|67|ref}}</ref>

He shares his information on the "[[Number]]s" with Yuma and is capable of somehow manipulating the "Numbers" cards, this is seen in two ways, one is that without Astral present Yuma is unable to play any "Numbers" for they do not appear on his [[Extra Deck]].<ref name="ep3" /> The second is that as so far seen, Astral can pull a "Numbers" card out of a defeated opponent without direct contact, although it is unknown if this is also linked to a rather psychokinetic ability. Furthermore unlike those who use [[Photon Hand]], Astral seems to be the only who can extract the card itself without taking a possessed Duelist's soul, however he was unable to take [[Trey]]'s "Number" due to the crest protecting him.<ref name="ep44">{{episode|Yu-Gi-Oh! ZEXAL|44|ref}}</ref>

The next day, a wave of energy from the [[Astral World]] and another world passed through Earth causing time to temporally stop and allowing Kite to invade his memories. This caused immense pain to Astral, and figured out that Kite was invading his memories. While traveling throughout the city, Astral told Yuma that he fears that something bad might happen if they find all the "[[Number]]s". Later, Astral and Yuma met up with Kite, who subsequently told them that they would meet again in the [[World Duel Carnival]].<ref name="ep25">{{Episode|Yu-Gi-Oh! ZEXAL|25|ref}}</ref>

Later at night, Yuma, Astral, and Tori meet [[Kite Tenjo|Kite]]'s younger brother [[Hart Tenjo]]. After witness Hart's power, Astral learned Hart is able to communicate with him, much to his surprised. Wanting to talk to Hart, Astral asked Yuma to take Hart with them back home, and Astral formed a friendship with him. After Hart went on a search for Kite, Yuma and Astral goes to find him, who he went berserk after failing to find his brother. Astral flies to Hart and touched his head to see Hart's memories and what he wants. Astral explained to Yuma the Hart that he want to get caramel for Kite, allowing Yuma calmed Hart down with it. Then [[Quinton]] comes out of a helicopter to take Hart with him using his [[crest]], but Hart revealed his mission to destroy the [[Astral World]] before he left, which horrified Astral.<ref name="ep40" /> [[File:AstralItHelpsHaruto.jpg|thumb|200px|left|Astral helping Hart.]] After Hart's kidnapping, Astral reminded Yuma of his previous Duel with Kite in that he mentioned he sold his soul to a devil to save his brother. Astral thinks he is referring to [[Mr. Heartland]] and solidified his theory of the carnival being used to hunt "Numbers". As he, [[Yuma Tsukumo|Yuma]], and [[Tori Meadows|Tori]] searched for Hart with Kite and [[Orbital 7]], he found the location through the description Hart projected in his mind. Once they arrived, [[Trey]] and [[Quattro]] challenged Yuma and Kite to a Tag Duel.<ref name="ep41">{{Episode|Yu-Gi-Oh! ZEXAL|41|ref}}</ref>

When Yuma and Astral reached the "[[Space Field]]", Astral listened to [[Quinton]], revealing the connection between Yuma's father, [[Dr. Faker]], and Vetrix. After hearing about the sacrifice used to open a gate to another dimension, Astral compared it to Xyz Summoning.<ref name="ep55">{{Episode|Yu-Gi-Oh! ZEXAL|55|ref}}</ref> After [[Kite Tenjo|Kite]] won against Quinton, Astral muses that when Vetrix and Dr. Faker began their plans, Astral entered this world. He says that must mean that the will of Yuma's father is in the [[Astral World]], and vow to defeat the adults with Yuma.<ref name="ep56">{{Episode|Yu-Gi-Oh! ZEXAL|56|ref}}</ref> In the "[[Magma Field]]" field, they confront Vetrix again and learned about his plans to use [[Reginald Kastle|Shark]] to as assassin to defeat Dr. Faker.<ref name="ep57">{{Episode|Yu-Gi-Oh!

ZEXAL|58|ref}}</ref> At the "[[Desert Field]]" field, Astral saw that Yuma was playing a defensive strategy, and told Yuma that he can't win this way and that he was afraid after seeing the other Duels. Astral muses that Kite and Shark are strong and have powers that can be feared, and he understands how Yuma could be scared of them. However, Astral comment how Yuma gotten over those sorts of fears before, making Yuma feel more confident now and win against Nistro.<ref name="ep59">{{Episode|Yu-Gi-Oh! ZEXAL|59|ref}}</ref>

While suffering in the Sphere Field, Astral watched Yuma, [[Kite Tenjo|Kite]], [[Reginald Kastle|Shark]]'s Duel against [[Dr. Faker]]. Astral muttered that he'll leave this to three of them and that the future is in their hands.<ref name="ep69">{{Episode|Yu-Gi-Oh! ZEXAL|69|ref}}</ref><ref name="ep70">{{Episode|Yu-Gi-Oh! ZEXAL|70|ref}}</ref> When [[Vector]] took control of Dr. Faker, Hart managed to free Astral from the Sphere Field Cannon. Fusing his soul with Yuma's, they equipped "Utopia Ray" with "[[ZW - Ultimate Shield (anime)|ZW - Ultimate Shield]]". With the helped of "[[Xyz Unity]]", Kite's "[[Neo Galaxy-Eyes Photon Dragon (anime)|Neo Galaxy-Eyes Photon Dragon]]" and Shark's "Shark Drake Veiss", they destroyed the "[[Number 92: Heart-eartH Dragon (anime)|Number 92: Heart-eartH Dragn]]" and defeated Vector. After escaping from the crumbling [[Heartland Tower]], Yuma challenged Kite to a Duel to determine the "true" winner of WDC, which Astral readily agreed to have the "true final".<ref name="ep71">{{Episode|Yu-Gi-Oh! ZEXAL|71|ref}}</ref>

===Yu-Gi-Oh! ZEXAL II===

Later, Astral was inside the [[Emperor's Key]] again, musing that he has collected fifty "[[Number]]" cards, and was determined to find the other fifty. He then recalled the memories of the "[[Number]]s" one by one and gathered his memories, oblivious to Yuma's current anxiety. After [[Mizar]] targeted Yuma with the [[Barian Sphere Cube]] and began a Duel, Astral comes out of the key and Yuma explained to him that Mizar is a [[Barian]] and learned the he could see him. Watching Yuma's Duel tactics, Astral comments how he expected Yuma to use "[[Overlay Barrage]]" instead of "[[Overlay Chain]]"- a defensive card. Yuma told Astral that he has to be cautious, which Astral was about to praise until Yuma cut him off, making him worry. Once Mizar Summoned his "[[Number 107: Galaxy-Eyes Tachyon Dragon (anime)|Number 107: Galaxy-Eyes Tachyon Dragon]]", Astral was greatly shocked of a "Number" outside of his 100 memories appearing before him.<ref name="ep82">{{episode|Yu-Gi-Oh! ZEXAL|82|ref}}</ref> When Yuma became too weak to continue Dueling, Astral looked after him as [[Kite Tenjo|Kite]] took their place. Astral watched Mizar unleash his true power and was stunned when he Summoned his "[[Number C107: Neo Galaxy-Eyes Tachyon Dragon (anime)|Number C107: Neo Galaxy-Eyes Tachyon Dragon]]". Once the [[Sphere Field]] began to collapse, Astral was freed from the Sphere, but watched in horror as Yuma and Shark fell down a cliff.<ref name="ep83">{{episode|Yu-Gi-Oh! ZEXAL|83|ref}}</ref>

The next day, Astral stayed in the Key to recover from the effects of "Sphere Field". When [[Girag]] issued a challenged and accused [[Vector|Ray Shadows]] for hurting Alito, Astral advised Yuma that he should have faith in his friend and they decided to Duel without Ray. However, Ray ended up joining them after all, which worried Astral as he saw Ray as a terrible Duelist. He warned Yuma that Ray would only hinder them and that they couldn't lose against Girag with the "[[Number]]s" at stake. During the Duel, Astral was affected by the "Sphere Field" again and fell to the ground, telling Yuma that protecting Ray is too risky.<ref name="ep87">{{episode|Yu-Gi-Oh! ZEXAL|87|ref}}</ref> Astral was forced to retreat to the Key to recover and felt the damage Yuma took in the Duel, but sensed that Yuma won the Duel in the end.<ref name="ep88">{{episode|Yu-Gi-Oh! ZEXAL|88|ref}}</ref> Recovering inside the Key, Astral was confronted by [[Number 96 (character)|Number 96]], who told him he couldn't win against the [[Barian]]s without accepting his evil side. Astral refused to believe this and sought answers from the "[[Number]]s" when the [[Shadow Giant]] appeared before him, saying that he must be tested. Once Yuma was inside, they Dueled against it, using their "Numbers" against the Giant's "[[Unformed Void (anime)|Unformed Void]]", and having great trouble. On the verge of losing, Number 96 reappeared before Astral to remind him of his advice, saying that something may happen to Yuma if he loses inside the Key. Fearing for Yuma's safety, Astral decided to undo the seal on "[[Number 96: Dark Mist (anime)|Number 96: Dark Mist]]" and grudgingly worked together with him to win the Duel. Afterwards, Astral and Yuma talked with [[The Door]] and was shown Astral's true memories, learning that his mission was to obtain a powerful card known as the [[Numeron Code]] that could affect destiny. They were then transported outside the Key, where Astral received another warning from Number 96 that there would be events in the future that would require him to become evil.<ref name="ep89" />

At times, Yuma doesn't openly admit that he was worries or cares about Astral, usually feigning anger and yelling at him, which only makes Astral smile because he can tell Yuma's true feelings. In dire situations, Yuma openly shows concerns and proclaimed he will do anything to protect him from danger. It shown that Yuma deeply cares for Astral as he couldn't believe Astral would leave and as he cried for his death.<ref name="ep48" /> Astral has shown many times how much he cares about Yuma, willing to give up his life for Yuma's safety.<ref name="ep18" /> Astral has also been seen smiling more since Yuma told him that he is his friend, and encourages Yuma to never give up. Later, it was revealed that Astral has been teaching Yuma how to Duel, since one day he'll disappear and Yuma will have to fight alone. He also said that when he disappears, he would want to leave proof that he exists in Yuma's memory and heart.<ref name="ep48" /> After Astral was revived, Yuma was greatly relieved as he cried tears of joy.<ref name="ep50" />

After Yuma dreams about being warned by [[The Door]] that someone is planning to take something most important thing to him, he feared that he will lose "[his] Astral". Not willing to put Astral in danger and be taken away from him, Yuma left his key to Tori in order to protect him and goes to Duel with a Barian-brainwashed [[Fender]] by himself. During the Duel, Yuma thinks that he the only one that can protect him and reflected how Astral is always the one protecting him.<ref name="ep74" /> In the key, Astral can receive the damage Yuma takes and knows Yuma is Dueling alone, which disappointed him since they are "partners". Once Astral got to Yuma, Yuma confined to Astral about his dream and states how he couldn't protect him. However, Astral told Yuma that he was proud of him and that he's a true friend, and will not forgive anyone who hurts him.<ref name="ep75" /> After nearly losing to [[Mizar]] and becoming shaken, Astral and Yuma grew even closer as they reaffirmed their desires to Duel together.<ref name="ep84" />

During Astral's first Duel against [[Kite Tenjo]] with Yuma, he developed a great fear toward him after seeing he Dueling skills surpassing his own and nearly beat him and Yuma.<ref name="ep13" /><ref name="ep14" /> This left Astral severely depressed for some time and was reluctant to face him again.<ref name="ep15" /> However, Astral eventually overcame his fears towards Kite as his bond Yuma grew stronger.<ref name="ep18" />

At the end of WDC, Astral told Kite, who could now see and hear him, that he considered him as a friend when encouraging to continue his rematch against Yuma.<ref name="ep72" />

===Reginald Kastle===

Knowing Shark is trustworthy and strong-willed, Astral has no problems letting him keep "[[Number 32: Shark Drake (anime)|Number 32: Shark Drake]]" card in his possession.<ref name="ep68" /> After the Duel with [[Vector]], Shark can now see and hear Astral,<ref name="ep72" /> but they still have little contact with each other.

===Numbers===

Eventually, Astral was managed to obtain of all the "Numbers", finally restoring his full memories and gaining sole control over them.<ref name="ep143" />
