Although no proof has shown, yet she claims to be best friends with Arles Azazel. Altana has claimed she appeared before Arata to make him stronger in order to beat the goddess.

Chronology
Altana was only mentioned at first by Master Biblia at her whereabouts when he visited Heaven, at that time she was only referred to as "She" and not her name. Aetheria brushes his answers of by saying that she hasn't seen her for many years, even lost count, and might be playing in the outside world. However Harukage seems to know where she is, as she informed the latter that she had sent a letter to them at some point that she was headed to "Demise".

Altana is first seen observing Arata and Harukage conversation from high distance in the sky, she laughs at amusement. She finds the "memory" of the Great Demon King interesting. She mentions her curiosity about him. Then she calls him a beloved Great Demon King. She boasts about herself to him if he can reach her level.

When Pandora was speaking to Arata, thanks to his failure of defeating the goddess and the world is in a state of collapsing, Altana suddenly appears and laughs, calling that Arata's child form is rather cute. Floating above them, she remarks that the genre is Oneshota, she goes on and says that Archangel and Great Demon King Oneshota thing, and laughs. But tells him there are also misunderstanding, and so her school is ok to attack Shota, asking Arata if she can do perverted things. However all of this confuses Arata and even wonder who she is. Altana then disappears and reappears, hugging him, informing him that she is an Arbitrator, as well informing her name. She then lifts the child Arata up, and changes the subject to better get refreshed first. Arata is then teleported to a bath whom he nearly drowns due to his size. Altana comes behind him suddenly seemingly enjoying the time with him. She now naked, tells him that she is happy with a smile, hugging the child. Altana informs four mysterious girls about Arata condition, being very weak since he is just reincarnated. Saying that he is can't beat the goddess as he is right now, She tells Arata that these four will be his teachers from now on. Altana also tells him about their abilities, including Pandora. As well as encouraging him, and from now on Arata will be involved in the future gods drawn by her best friend Arles Azazel.

Finally she tells him to start the best counterattack drama that saves all dimensions rather than all the space and time of the whole world. After many days of Arata's training with the four Demon Lord Knights has, Altana appears next to Arata while he is in bath and Pandora who is there as well. Pandora notices that she has been injured with black substance. She informs them both of the terrible news that Aryan has figured out that Arata has been reincarnated in another world and managed to find him, having tracked his movements.

Harukage in a new form as one of the goddess underlings, appears before them and introduces herself. While Altana is resting in the bath to recover her injuries. Informing Pandora that she is injured and can't help her with her fight. Even her injuries hurt she laughs, which Pandora annoyed by her statement as it is not a laughing matter. Altana then continue resting in the bath, while remaining as an observer. She observe Pandora and Harukage fight, while commenting how tsundere she is to allow Arata to escape, only for her to reply that since Anna believed in him so she will too. Much later when Arata has an idea to talk to Harukage, Altana thinks that something has started or is about to start.

With everyone present including the Demon Lord Knight, Harukage and Arata start to converse with the former proposes only to ask one questions. Arata asks Harukage if she's wearing any panties, due to her always wearing a kimono. Much to everyone surprise, for the said question including the goddess itself who enters a state of shock.

She used to have both wings white, giving her an angelic appearance, and was also able to hide them at will, however her right wing turned black. This is probably due to the experiments she used on Ana to make her a Demon King, or at the cost of using her wings to use her ability to change the world in "Demise" when she managed to make a rift to open up the world for Ana and the co.
