During their decade-long quest to defeat the Demon King, the members of the hero's party—Himmel himself, the priest Heiter, the dwarf warrior Eisen, and the elven mage Frieren—forge bonds through adventures and battles, creating unforgettable precious memories for most of them. However, the time that Frieren spends with her comrades is equivalent to merely a fraction of her life, which has lasted over a thousand years. When the party disbands after their victory, Frieren casually returns to her "usual" routine of collecting spells across the continent. Due to her different sense of time, she seemingly holds no strong feelings toward the experiences she went through. As the years pass, Frieren gradually realizes how her days in the hero's party truly impacted her. Witnessing the deaths of two of her former companions, Frieren begins to regret having taken their presence for granted; she vows to better understand humans and create real personal connections. Although the story of that once memorable journey has long ended, a new tale is about to begin. [Written by MAL Rewrite]

In the deadly battle at the Watergate City of Priestella, Subaru and his allies barely emerged victorious—but their triumph came at a great cost. Through the "Authority of Gluttony," Rem was put into suspended animation, while Crusch's memories and even Julius’s name were devoured. As he searches for a way to save them, Subaru learns of the "Sage" Shaula—an all-seeing being said to possess every form of knowledge. His next destination is the Pleiades Watchtower, home to the Sage, the farthest tower standing in the vast, uncharted desert known as the Auguria Dunes—a place so perilous that even the mightiest "Sword Saint," Reinhard, failed to conquer it. The fury of nature, unknown magical beasts, and unimaginable dangers lie ahead. Together with his friends, Subaru embarks on a life-risking journey to reclaim what was lost. (Source: Kadokawa, edited)
