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, she calls the scenery 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.
