Eleanore de Victorique
- Voiced by: Mari Oda
The Dark Lord of Necrograd. Before taking control of her own nation, she was one of the scientists that first discovered and learned how to manufacture Tactica, and befriended Leonhardt while he was being converted into a living weapon.

Tsubaki
- Voiced by: Yuuki Kajita
The Dark Lord of Rakshasa. In terms of physical might, Tsubaki is considered to be the strongest of the land's leaders. However, she dislikes complicated strategies and boredom, frequently leading to sneaking away from her duties for a cup of sake and lectures from her subordinate Ayame when she returns. Despite her flaws, she genuinely wants the best for her nation, and is serious when it comes to protecting it. Her Tactica power, "Raioumaru", allows her to attack with a devastating amount of lightning.
