Antera  

Anju, 安底羅

Antera is one of the Juunishinshou, despite being young, she possesses superhuman strength and wields two large hammers. She belongs to the Mibu Clan and carries the Death Disease, which has halted her aging process in an attempt to stop its spread since there is no cure available. Her real name is Anju, and she is the daughter of Kubira I. During the battle against Akira, Antera injected herself with a stimulant that transformed her into her true form as an adult named Anju. However, upon transformation, the Death Disease resurfaced, causing her to begin dying. When Akari removed the stimulant from her body, turning her back into a child, Antera lost all her memories and became a typical kid.
