Vali Laufey
The main protagonist, directly descended from Loki Muspelheim. Because his demonic heritage is physically obvious, he was abandoned by relatives that were devoted to the Holy Senate, and taken in by Berg to serve as a soldier and fight for demon liberation. An encounter with a boy that's also named Loki leads to Vali being entrusted with the Heart of Yggdrasil, which can grant him the power to dominate the land and turn the new generation of goddesses, including his half-sister Brynhildr, into his corrupted subordinates.
- Ambiguously Related: To Brynhildr; although they're both descended from Loki and treat each other Like Brother and Sister, the exact point within the past 500 years when the Laufey and Asgard family lines split is kept ambiguous. Due to the Senate's interference, it's also unclear when the "Muspelheim" name was dropped.
- Spin-Offspring: Vali is a descendant of Loki and Tyrca.
- Villain Protagonist: Although he can choose a path that avoids corruption, one of his initial goals is to subjugate Brynhildr, his (more or less) own half-sister.
Linde Wezlung
- Voiced by: Aiko Ookubo
The younger sister of Sieg, Vali's friend in the demon liberation army. She has a huge crush on Vali, to the point that she willingly sides with him over her brother and acts as a captain of Vali's forces, but worries that Vali is too interested in pursuing the goddesses to care about her desires.
- Always Second Best: She's worried that, given the power of the Goddesses compared to her own, Vali will never reciprocate her love.
- Draconic Humanoid: The dragon side of her bloodline manifests mainly with her tail and horns, otherwise appearing like an ordinary humanoid demon.
- Half-Human Hybrid: The Wezlung family tree is half-demon and half-dragon.
- The Lancer: She remains Vali's loyal #2 through thick and thin, if mainly out of affection.
Loki
- Voiced by: Harumi Asai
A mysterious boy that's oddly intelligent for his age, and may in fact be Loki Muspelheim himself, but is still treated as a child by Vali. He's responsible for entrusting Vali with the Heart of Yggdrasil, but his motivation for doing so is a mystery.
- Cassandra Truth: Vali treats him like the child he appears to be, not believing that Loki's his ancestor.
- Fountain of Youth: He's a younger-looking version of the original Loki, and one of the game's mysteries is learning how his appearance changed so drastically.
- Guest Fighter: Both of the forms he has in this game appear in Venus Blood -Hollow- as battle-only units, alongside both of his forms from Venus Blood -Frontier-.
- Previous Player-Character Cameo: Despite his current youthful appearance, he is the same Loki from Frontier.
- The Smart Guy: He serves as Vali's strategist.
- Wise Beyond His Years: Averted; Vali can remark that he serves as an excellent tactician despite being a mere child, but that's because Loki's actually much older than he looks.
Norns
- Voiced by: Akane Sanada
A shrine maiden that was formerly a part of the Imperial Senate, but was imprisoned by them after opposing Vesla's desire for complete supremacy of the goddesses over the world's inhabitants. Despite Norns' soft demeanor, she has an inner strength that makes her hard to silence.

- Miko: Her duty before imprisonment was to act as one.
- Reincarnation: She's the reincarnation of Fena, Loki's former adjutant who died in a Heroic Sacrifice during the events of -Frontier-.
Brynhildr Asgard
- Voiced by: Maki Tomonaga
The Goddess who protects the Valhalla region that was formerly Odin's domain, who has a sibling-like relationship with Vali. She is descended from both Odin and Loki, but manifested divine power instead of demonic; this led to the Senate supporting her, making her a prime target for the demon liberation forces.
- Spin-Offspring: Is stated to be descended from Loki and Odin, though due to the Senate backing Nanna as Odin's successor because of Brynhildr's ancestry, her role is more akin to Tyrca's.
Fana
- Voiced by: Noriko Fujimoto
The Goddess who protects Jukai Helgrind, the southern region. Fana's an elite warrior descended from goddesses and dragons, who is also a member of a powerful noble family, but her manipulative mother-in-law Sigyn has led to Fana trying to estrange herself from them.

Nanna Odin II
- Voiced by: Miya Serizono
The youngest of the goddesses, who is being groomed by the Senate to take over as Odin's successor and ruler of her own holy empire. Despite being imbued with Odin's spirit and inheriting Odin's weapon, the multi-bladed Gungnir, Nanna can only control two of its blades. Nanna genuinely wants to be a leader that can make others happy, but this conflicts with a desire to play and enjoy the kind of fun that the Senate prevented her from having.
- Guest Fighter: She appears in Venus Blood -Hollow- as a battle-only unit, in Default, Corrupted, and Broken forms.
- I Just Want to Be Normal: Although she does understand the responsibility of her role and genuinely wants to be a benevolent leader, Nanna also wishes she had an ordinary upbringing full of love and happiness instead of Vesla's strict supervision.
Vesla

The leader of the Holy Senate, who wants to create a Holy Asgardian Empire in which the goddesses dominate all other races, especially demons.

Vesla also serves as a surrogate mother for Nanna, and struggles with Nanna's personal desires interfering with her grand ambition.
- Big Bad: Her Senate is entirely to blame for the current war between demons and goddesses.

Sieg Wezlung
- Voiced by: Takeaki Masuyama
Linde's brother. Although he and Vali become friends while in the demon liberation army, Sieg's draconic ancestors were always mere shadows to Loki's legacy, and he would rather compete with Vali to oppose the goddesses and unify the world instead of letting history repeat itself.
- Always Second Best: To Vali.
