Freezing Astaroth is a supreme leader in Kisaragi.

Daughter of the Kirasagi Conglomerate president, she founded Evil Organization Kisaragi alongside Belial the Great Flame and Lilith the Dark, receiving ice manipulation powers after being operated by the last one. Astaroth was begged by Six to join the organization whilst begging for incoherent things such as being the husband of hers.

Astaroth is one of the three generals in the evil organization, the Kisaragi Corporation. She and her co-worker, Belial, assigned Combat Agent Six to a reconnaissance mission to an alternate world. A high-performance android named Alice is assigned to join him on his mission by her as well.
