Frieren: Beyond Journey's End, Volume 6 (by Kanehito Yamada & Tsukasa Abe)

The adventure is over but life goes on for an elf mage just beginning to learn what living is all about. Elf mage Frieren and her courageous fellow adventurers have defeated the Demon King and brought peace to the land. But Frieren will long outlive the rest of her former party. How will she come to understand what life means to the people around her? The mages begin the second stage of their certification exam: a dangerous expedition into the innermost depths of the ruins of the king’s tomb. This time, there are no teams and it’s every mage for themselves. Whether they want to team up or not, the challenge they will face—their own clones—will push their skills to the limit.
