This Polygon feature is a curated list ranking five anime story arcs the writer considers essentially flawless, praising them for high stakes, meaningful character growth and satisfying, well-paced conclusions. The list opens with the Promised Day arc from Fullmetal Alchemist: Brotherhood, which resolves the antagonist Father's centuries-long plan and brings the Elric brothers' journey to a close, before moving to the Golden Age arc from Berserk, adapted across three films exploring betrayal and psychological trauma between Guts, Griffith and Casca.

The piece frames its criteria around convincing conflict, evolving character motivations and cathartic payoffs, citing Hunter x Hunter's Chimera Ant arc and Jujutsu Kaisen's Shibuya Incident as near-misses that inspired the ranking. The full list of five spans well-known shonen and seinen titles, though the article text provided cuts off before revealing entries three to five, including the "pure shonen excellence" arc teased in the headline. Note: this article contains spoilers for all the arcs discussed.
