Tale of the Secret Saint (Manga) Vol. 12, A

REUNIONS AND REMINISCENCE!
At long last, Fia reunites with her beloved black dragon Zavilia atop Blackpeak Mountain, although her companions–Kurtis, Green, and Blue–are rather rattled! The joyful reunion gives way to introspection as Fia listens in on conversations about a great emperor from three hundred years ago…and wonders if it may connect to her previous life. But as Fia takes time to confide in her dear Zavilia, her companions encounter a strange girl with raven-black hair…
Series Overview: Born into a family of knights, Fia has always dreamed of following the path to knighthood too, except she’s the least talented of them all. On the day of her initiation test, a deadly injury prompts her life to flash before her eyes…and reveal her former life as a powerful Saint who defeated the Demon King in a bygone era! Her painful death as a Saint made her swear she’d never accept sainthood and its dangers again. But now, with her saintly power returned, Fia has the chance to be a more powerful knight than she’d ever dreamed—that is, if she can last long enough!
