The golden orb, gifted to Aru during the Claiming, is an important recurring symbol in the story, which signifies multiple things. As an enchanted object, it plays an important role in the plot, as it marks Aru as Indra’s daughter when she is presented with it during the Claiming. Initially, Aru is unsure how it will be useful; however, when battling Madame Bee, Aru discovers that it shines “heavenly light,” which allows one to see things clearly. This is significant because Aru is the reincarnation of Arjuna, a warrior who was known not just for his valor, but also his intelligence and vision. Aru’s ability to wield the orb in a manner that sheds clarifying light symbolizes that she possesses similar qualities.

The golden orb later reveals its true form as vajra, Indra’s weapon. In Sanskrit, vajra means both “diamond” and “thunderbolt;” accordingly, in mythology, the vajra is considered to be one of the strongest weapons to exist, carrying the thunderbolt’s sharp aim and the diamond’s indestructibility. This symbolizes the kind of focus that Aru discovers within herself when she successfully escapes the illusions inside the Palace. Furthermore, the vajra’s revelation marks a crucial turning point in the story: The girls prove themselves worthy of wielding celestial weapons when they heroically save each other’s lives.
