Frieren: Beyond Journey's End, Vol. 11 (11) 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?

Frieren has broken the curse of Diagoldze and released herself and Denken. Now they face Macht and Solitär in a final battle of retribution. With his memories of his wife driving him, Denken challenges Macht, his former master. Frieren takes on Solitär, who is confident of victory. But demons have always underestimated Frieren, one of the greatest mages to ever live, and Macht and Solitär would do well to not count Frieren out just yet!
