ONA
Description
Anne is a major supporting character introduced in the Forest Land arc of the anime. She is the princess of Forest Land, the daughter of the deposed King Jam and a powerful demon named Lilith. This heritage makes her a half-demon, a fact that significantly shapes her identity and the challenges she faces. Because her mother is the daughter of the Demon King Satan, Anne is also the niece of the demon prince Beelzebub.

As a child, Anne lived a sheltered life of royal privilege. This ended when a coup d'état, orchestrated by the angel Muniel and Supreme Commander Bred, overthrew her father's rule. Her father was imprisoned, her mother was sealed away, and Anne was forced to flee, becoming a fugitive in her own kingdom. For a decade, she lived as a member of the resistance, working to restore her family's rightful rule and free her parents.

In terms of personality, Anne is defined by a strong balance of rational thought and passionate conviction. She is courageous and quick to make decisions, as demonstrated when she first meets Beelzebub, Thief, and Rao; despite initial caution, she quickly assesses them as trustworthy allies. She is compassionate and cares deeply for the people of Forest Land, including those who have been turned against her because of her demonic heritage. While she often clashes with the impulsive and mischievous Beelzebub, their dynamic is that of equals who genuinely respect each other, even before they learn of their unusual family connection.

Anne’s primary motivation is the restoration of peace to Forest Land and the liberation of her family. She is driven by a sense of duty and a desire to reclaim her homeland from the corrupt forces of Muniel and Bred. Beyond her political goals, she harbors a deep, personal passion for engineering. Being a mechanic is not just a skill for her; it is her true calling, and she finds genuine joy in tinkering with and improving technology.

Her role in the story is pivotal. She serves as the guide and connector for the protagonists in the unfamiliar territory of Forest Land, leading them into the conflict against the new regime. She is not merely a passenger but an active combatant and strategist. Her mechanical expertise is crucial, allowing her to repair vehicles, disable enemy weapons, and even avert a major disaster by using her knowledge to convert the energy of powerful aquanium reactors into a source of water. Her capture by enemy forces also becomes a key emotional driver for the group, transforming their mission from a simple task into a personal rescue operation.

Anne’s key relationships include her close bond with the resistance and her father’s former aide, Rango. Her friendship with Rao, Beelzebub, and Thief evolves from a temporary alliance into a genuine found family, with her decision to join them in their travels at the end of the series highlighting this connection. Her relationship with Beelzebub is particularly complex, shifting from bickering companions to something more significant after the revelation that he is her uncle.

Throughout the series, Anne undergoes significant development. She begins as a princess in hiding, fighting for a cause she inherited. Over time, she steps into her own power, not just as a symbol of the old monarchy, but as a capable leader and engineer who saves the day through her own wits and skills. Her journey is one of self-acceptance, coming to terms with her demonic heritage not as a curse, but as a part of who she is.

Anne possesses several notable abilities. As a half-demon, she has enhanced physical attributes, including faster reflexes and greater durability than a normal human. When she accesses her demonic power, her eyes glow red, and she can emit a powerful scream that can temporarily paralyze those around her. Her most consistently valuable ability, however, is her expertise as a mechanic and engineer, which proves essential to the success of her allies' missions.
