10 Best Isekai Anime With Grand Adventure Quests, Ranked

Summary

• Isekai stories thrive on grand quests like battling gods or building nations.
• Some anime redefine survival and craft intricate worlds to drive the narrative.
• The journey in isekai series is just as important, often filled with moral dilemmas and growth.

At the heart of many great isekai stories lies a grand adventure or quest—a mission that drives the characters forward, whether it’s battling gods, building nations, or simply surviving against all odds, reminding us why we love isekai: because the quest is always worth it. Some, like Mushoku Tensei: Jobless Reincarnation, craft an intricate world where growth and redemption drive the narrative. Others, like Re:Zero – Starting Life in Another World, redefines survival itself into the ultimate quest. Then there’s That Time I Got Reincarnated as a Slime, where an unassuming slime rises to power and reshapes the world.

Whether it’s a fight for survival in Grimgar of Fantasy and Ash, a battle of wits in No Game No Life, or an assassin’s deadly mission in The World’s Finest Assassin Gets Reincarnated in Another World as an Aristocrat, these anime prove that the journey is just as important—if not more so—than the destination.

The Faraway Paladin

William G. Maryblood Journeys To Become A Knight And Uncover His Past

An unusual take on the isekai formula, The Faraway Paladin follows William G. Maryblood, a boy raised by three undead mentors in a ruined city, where he grows up isolated from the world but deeply connected to his guardians’ wisdom and love. His quest to uncover the truth about his origins and pursuit of knighthood is both personal and epic.

As he ventures beyond the city, Will faces moral dilemmas, battles dark forces, and grapples with the legacy of his mentors. But unlike many isekai protagonists who are dropped into adventure-ready scenarios, Will must first uncover the truth of his origins and the tragic past of his caretakers before he can embark on his journey. In short, it’s an earnest, almost old-school hero’s adventure, enriched by deep lore, moral dilemmas, and a sense of duty that makes The Faraway Paladin a truly grand quest.
