Muninn is a male character from the anime Record of Ragnarok II, adapted from the manga series. He is one of a pair of ravens that serve the Norse god Odin, alongside his counterpart Huginn. In Norse mythology, Muninn is associated with memory and thought, and this trait is carried into the story, where he functions as an observer and messenger for Odin. Within the narrative, Muninn appears primarily during the Council of Gods, attending the meetings that decide the fate of humanity. He is a supporting figure among the divine pantheon, often seen flanking Odin or reacting to the events of the tournament.

Personality-wise, Muninn displays a somewhat eager and impatient temperament. He expresses a desire to engage in conflict, particularly showing annoyance when direct action is delayed or when he is ignored by other deities such as Brunhilde. This suggests a combative and impulsive side beneath his role as a passive information-gatherer. His motivations align with those of the gods who vote for humanity's destruction, as he appears to support the decision to eliminate humans. However, his primary duty is to serve Odin faithfully, gathering intelligence and relaying it to his master.

In terms of role within the story, Muninn is a background character who contributes to the atmosphere of divine authority and tension. He and Huginn act as Odin's eyes and ears, occasionally commenting on the proceedings. Their presence reinforces the Norse mythological elements woven into the series. They do not participate directly in the Ragnarok battles, but their small interactions provide insight into the gods' internal dynamics.

Key relationships include his bond with Huginn, with whom he works in tandem, and his loyalty to Odin, his master. Muninn also interacts with other gods like Brunhilde, though his exchanges with her are marked by frustration when she disregards him. Development is minimal, as Muninn remains a static character without significant personal growth or arc across the series. His notable abilities include flight, heightened perception, and the capacity to observe events across the world and report back to Odin. These abilities make him a valuable asset in the gods' intelligence network, though he does not demonstrate combat prowess on screen. Overall, Muninn serves as a minor but memorable figure representing the mythological ravens of Norse legend within the Record of Ragnarok universe.
