Name: Reginn Gender: Female Race: Dvergr Height: 160 cm Relatives: Niðavellir (Ancestor), King of Niðavellir (Father), Queen of Niðavellir (Mother), Fáfnir (Oldest Stepbrother), Ótr (Older Stepbrother) Occupation: Princess of Niðavellir Weapon: Mech </Personal Information> Reginn is a young slender woman of an average height of 160 cm. She has pale skin, cyan hair tied into a ponytail and yellow eyes. Her attire consist of a black skintight bodysuit, white and purple cap, a gold armor plate on her crotch, black gloves and black shoes. Reginn is a kind-hearted, gentle girl who cares greatly for her brothers. Fáfnir and Ótr's sudden change in personality, which she states are full of rage, is deeply concerning to her. Despite this, she faithfully obeyed their orders in the hopes that they may one day return to their former selves. She even cried when she felt that she had failed them after being defeated by the Order of Heroes twice. However, her encounter with the Order proved to be a window for her to ask someone for help in the hopes of returning her two brothers to their original selves.

Considered as the tomboyish Niðavellir royal, she claims to be an excellent cook and is eager to show her cooking skills.

Reginn is also interested in machines, since her home kingdom Niðavellir is the kingdom of machinery. She is a genius mechanic as well, being able to build a battle mech of her own. Reginn does not remember much about her family aside from the fact that she was orphaned along with her older brother Ótr after the old king of Niðavellir was killed and the kingdom descended into chaos. Amidst the chaos, the siblings found shelter in a village where they were later discovered by Fáfnir who took them into his care. While supportive of her new stepbrother, his actions overtime became a concern for Reginn, especially when he began invading realms. Despite this, she remains supportive of him, in hopes that he would return to the kind king he once was.

When Fáfnir sets his sights on the Kingdom of Askr, Reginn is sent to lead the invasion and capture Kiran under Ótr's orders, though the reason behind it is not disclosed to her. This order leads to an encounter with Alfonse and his forces who have just recently escaped from Dökkálfheimr. Despite a well fought battle, she is defeated and forced to retreat. She later reengages the Askran forces and Alfonse notices that she lacks conviction in her actions. After being defeated a second time, she cries over her failure. Alfonse and Sharena console her, and seeing their kindness despite being enemies only moments ago, Reginn pleads to the Askr forces to help her stop her brother's madness.

On their way to see Eitri, a sage whom she believes can stop Fáfnir, Reginn and the Askran forces encounter Ótr who is stunned to see her cooperating with them. Reginn voices her intent to stop Fáfnir, leading to her brother disowning her for her betrayal of her kingdom.

On their way to the capital of Niðavellir, Ótr reveals that Reginn is actually the princess, her biological parents being the king and queen killed in the coup. It is ultimately revealed that, in fact, Reginn is the only legitimate heir to the throne of Niðavellir. Ótr is the son of commoners that lived in the royal castle who were inadvertently responsible in part for the deaths of Reginn's parents when she was a baby. Fáfnir, meanwhile, was an unfortunate man pulled into the world by Eitri's attempts to replicate the power of Breidablik and rendered amnesiac. Reginn confronts Ótr, who is so obsessed with keeping Fáfnir from regaining his memories at the risk of losing his "brother" that he goes to extreme lengths, but Ótr dies at the hands of Fáfnir after the latter turns into a monster. Reginn brings a stop to Fáfnir, who regains his senses after being dealt a mortal blow.

With both of her brothers dead, Reginn confronts and strikes down Eitri, who in the end reveals that Reginn's ascension to the throne was her goal all along. Reginn is a mechanical genius. In battle, she rides a four-legged mech that uses a sword and shield.
