From Pixiv creator DC Ultra, whose works follow the story of university student Anna Blackthorn, who has taken on the burden of being her planet's hero, Ultra.

In an interlude seemingly unrelated to the story, we see events which took place years prior at the University. In the first, a young woman named Gabriella attempts to avenge the wrongs done to her and other girls by a male teacher. In the second, a young woman named Lana with strange powers attempts to avenge Gabriella. Gallery contains Avenger and Bloodline (which starts on page 165).
