However, these developments lay the groundwork for future arcs.
Likewise, the Labyrinth Arc marks a major turning point in Rudeus Greyrat’s character development, helping him realize the true importance of family and become a better person, fulfilling the growth fans have long hoped to see.

The John Smith Arc is one of the most entertaining in the series, allowing Cid to act even more recklessly and unleash his abilities without restrictions as he indulges in his wild fantasies. His interactions with Yukime also add another layer of enjoyment to the arc, and if that weren’t enough, the ensuing conflict delivers plenty of hilarious misunderstandings and unexpected twists that make it well worth revisiting.

Overlord’s Holy Kingdom Arc Is Filled With Political Deception
Ainz Ooal Gown’s reign of terror continues in Overlord, but this time, the Holy Kingdom Arc takes the form of an anime film rather than a traditional season consisting of multiple episodes.

Still, the Holy Kingdom arc delivers intense battles, brutal confrontations, and high-stakes geopolitical conflicts that showcase the terrifying extent of Ainz’s power. It stands out as one of the series’ most well-written arcs, showing how easily humans can be manipulated through fear, desperation, and carefully orchestrated schemes.

Before long, Rimuru establishes his own nation, gathers powerful allies, and eventually ascends to the rank of a Demon Lord.
Speaking of Demon Lords, Tensura’s Birth of a Demon Lord Arc thrilled audiences with one incredible moment after another. From Rimuru’s devastating Megiddo attack against Falmuth’s forces to the Lord of Wisdom Raphael temporarily taking control of his body, the arc delivered plenty of unforgettable highlights.
