A young Alicia learned of the history of the dark lands from her father Margo and inspired to be an adventurer. When Alicia grew into a young adult, Margo was killed in an attack. In the present, Alicia is now a member of a group of thirteen heroes sent by the kingdom's royal family of Haiden to slay the demon king Clevatess, which is unsuccessful. As a result, all the heroes are killed. In retaliation, Clevatess invades and destroys Haiden, killing its king. Before leaving the palace, he reluctantly accepts a dying boy's final request to take care of a baby. He soon revives Alicia with an immortality curse that forces her to serve him and requests that she breastfeeds the baby, which she is unable to do since she is a virgin. They ultimately decide to hire a wet nurse and take some arcanacites as payment. Clevatess soon takes a human form under the alias Clen and names the baby Luna. While taking care of Luna, Alicia discovers that Luna is of royal blood. They are then captured by bandits. Meanwhile, a man named Favio discovers that the king of Haiden foolishly attacked the dark lands while another kingdom attempts to get its hands on the arcanacites in Haiden. | ||||||

Clen reveals that he is weaker in human form and intends to stay this way until Luna becomes king. In turn, Alicia reveals that they are captured by a group of slave traders called the Crows. Arriving at their hideout, Alicia is brought to see the boss while Clen is made to work in the kitchen where he meets Nell, a slave girl, and the kitchen's owner, Carme. Upon meeting Broco, the leader, and his pet troll Betty, he demands that Alicia takes them to where her allies' weapons are, but she refuses. Meanwhile, Nell breastfeeds Luna before she is punished by a couple of the members of the Crows. Once Clen kills them, he requests her background. After she explains it, Clen attempts to hire her as Luna's wet nurse, but she declines. Elsewhere, Alicia is brought to a flooded mine swarming with Arvensis where she learns the Crows are after a sword belonging to the hero Khord called the Regalia, which is located at the bottom. When a blind bandit named Fleeto threatens to rape Alicia, she causes them to fall from a great height in hopes that Clen's curse will ensure that she survives. | ||||||

Believing Alicia to be dead, the other bandits decide to go down to investigate. Alicia's theory is right as she has indeed survived and Clen contacts her, who tells her about Nell. Alicia suggests killing all the bandits, but Clen explains that she has to be the one to kill them before healing her. The bandits are shocked to see that she survived and prepare to attack her, but she manages to hold her own against them while recalling her father's training. She then lures out the Arvensis by knocking some of the bandits into the mine before diving into it to get the Regalia. Elsewhere, Nell returns to work in the kitchen and questions Carme about her origins, but she refuses to say. Broco, having been overhearing their conversation, learns of Luna's presence and takes Nell away. Inside a dark tunnel, he feeds her to Betty in retaliation for her betrayal. Clen then shows up and when Broco orders Betty to attack, she instead reacts in fear and barfs Nell out as Clen moves her and Luna away. Broco uses mind-controlling magic to make Betty attack Clen. | ||||||

Despite her immortality, Alicia suffocates as she reaches the bottom. While she finds the Regalia, she is attacked by another monster called the Ancient One. When Alicia returns to the surface, she refuses to help the bandits and leaves them to be killed. Meanwhile, Clen manages to defeat Betty, but is unhappy that Alicia did not tell him about the mind-controlling magic. When Broco attempts to flee with Luna, a still alive Nell grabs him. Alicia cannot clear away the magic smoke as she has no magical abilities. Seeing that Luna is what is pacifying Clen, Alicia decides to help find Luna. When she does, Broco threatens to injure Luna. Alicia throws the Regalia into a wall as a way to get Broco to relinquish Luna, but he is unswayed as he still desires the weapons that the thirteen heroes used and considers Luna more valuable. Broco tries to escape using invisibility magic, but fails and is killed by Alicia as she can still hear him and Luna. Clen is unable to heal Nell as his magic can only ensure the survival of one person, so Alicia willingly sacrifices herself. As a result, both Alicia and Nell, now referred to as Nelluru, are miraculously revived, with Nelluru now fully healed. | ||||||

Clen stores away the Regalia to avoid attracting unwanted attention, but promises to give it back if Alicia needs it. Nelluru is shown to be quite strong as she can carry heavy loads and Luna. Alicia is allowed to obtain the weapons and armor that she needs. A man named Gart ambushes them. Clen stops the fight and learns that Gart is after Broco, believing that Clen is his target. Once Clen clears up the misunderstanding and that Broco is already dead, he reveals that Gart is a dark beast in human form and works for another demon king named Zavthier, while introducing himself as a servant of Clevatess. Alicia is shocked to learn that there's more than one dark beast, but Clen explains that not all dark beasts can speak and take human forms. Grat reveals that Zavthier considers killing humans due to the Crows stealing young beasts from the dark lands and selling them to a group of mercenaries led by Vroko; Clen has been told of this by Carme. Alicia tells them about wizards and Dorel, who was responsible for killing her father. Meanwhile, a general named Rod learns from his second-in-command Miquel about their progress in their battle against Dorel's army.

After reemerging, Alicia is outmatched by the venomous bugs, but Clen summons the Regalia, allowing her to slay all the bugs and overpower Maynard; when he refuses to surrender, Alicia decapacitates him.

Clen reveals that Dorel actually imprisoned a decoy of him. After revealing that Dorel needs Luna to obtain the forge in Haiden, Naie escapes and attempts to abduct Luna and Nelluru, but Clen and Alicia, who arranged for this escape, easily catch up and take her hostage again, forcing her to levitate their wagon and serve as their means of transportation. They bid farewell to the villagers as they head for Haiden. Reaching the kingdom, they encounter an ongoing battle. Spotting Dorel, they head towards him as he fights T'ala and her forces. He easily overpowers them before Alicia arrives. As Alicia fights Dorel, Clen goes with Luna and Nelluru to find the forge.

Gart finds Clevatess's prison, but cannot free him, though he isn't aware that what is inside isn't the real Clevatess. He is confronted by Rod, who wants him to help after informing him of Dorel's plot. Gart agrees, but warns him that he will be killed if he doesn't agree with his conditions. Clen cannot open the forge's entrance even with Luna's help, so he enters through the chimney. Meanwhile, Nelluru is subdued by the still-alive Haiden king, who takes Luna and reveals himself to Clen. Meanwhile, the fight between Dorel and Alicia continues, with Alicia's immortality keeping her alive. Dorel reveals that 25 years ago, he and Margo used to be partners. Margo defeated him in a contest and is awarded with a Regalia sword by the Haiden king, but explains that it captures the soul of whatever it is slayed with first. When attempting to defeat a dragon from the Dark Lands, all of their party members were slain and Margo is badly injured, so he passes his Regalia to Dorel, who uses it to defeat the dragon. However, the sword's power absorbs the dragon's soul, which summoned a Demon King that corrupts him. He and Margo returned safely to the kingdom. After the flashback ends, T'ala and Alicia are horrified by this revelation as Dorel summons an undead dragon that knocks Alicia over the edge before he heads off to the forge. Having once again survived, Alicia attempts to warn Clen, but he is too preoccupied with another situation as the king attempts to throw Luna into the forge. | ||||||

Alicia is approached by T'ala and questions her about the heroes that Clevatess killed, with Alicia revealing that she's the only survivor. Alicia agrees to help and explains that her son, revealed to be Luna, is alive. They two proceed to the forge. Along the way, T'ala explains the history of the heroes to Alicia and does not wish for her son to be king under the forge's power. The Haiden King uses Luna to open the forge, but Clen stops him and questions his motives. The King explains that those who become king are thrown into the forge and are revived as the new king who cannot disobey the forge (which explains how the king was revived), also revealing that Luna's true name is Toth before dropping him in. Clen reveals that he has the real Luna and whom the king dropped into forge was a shadowy decoy. The king decides to drop himself into the forge to make it destroy Clen and Luna, triggering an explosion. Meanwhile, Dorel also heads to the forge, but is ambushed by Rod and Gart, though he survives. Alicia joins the fight, but Dorel still manages to overpower her and Rod. The two eventually manage to outsmart and kill him, but he revives in a much stronger form. After revealing his desire to eliminate all traces of heroes, he unleashes a deadly attack on them. Having survived, Clen finds the Book of Toah, a magical tome that appeared when the forge was destroyed, which is the cause of the forge's existence, Haiden's motives, and the heroes' attempt to kill him. Showing little interest, he decides to leave Luna and return home. | ||||||

Nelluru saves Alicia with her strength, but Alicia fails to defeat Dorel. However, she manages to break his sword. With the sword destroyed, Dorel is quickly killed in a gruesome way. Alicia fears that Vorden, the Demon King helping Dorel, may appear, but Clen appears with Luna and assures her that he won't. T'ala sees Luna and recognizes him as her son, but Clen lets Luna decide whom to go to and lets him walk to his mother. Luna and T'ala are reunited. Rod goes to inform the others of Dorel's defeat, and Clen reveals that he kept the Book of Toah. A salamander who works for Vorden warns him of his master's response to the situation, but Clen rebuffs this. With Dorel dead, the enemy soldiers and Naie either surrender or retreat. As Alicia recovers from her fight, Clen tells her about the history he learned from the Book and suspects that there are more of them. Favio comes and brings Clen's group to see T'ala and Luna in the throne room, where the former thanks them for their help in saving the kingdom. Despite Nelluru's fears, T'ala is grateful for her help keeping Luna alive. Clen then asks to become Luna's magic instructor as a reward, though Alicia is embarrassed with having to help him with an altered appearance. | ||||||
