Recurring Themes in Luminous Arc Series

In Luminous Arc Series, there are many recurring themes.

Antagonistic Witches[]

Vanessa(2) — Vanessa, the pioneer of Antagonistic Witches

In each of the Luminous Arc games, there will be one antagonistic witch toward the party due to conflict in morality or goal with the other witches. Generally, the party members will battle the said witch for the majority of the game until both sides come to term with their goals. Afterward, the said witch then joins the party and fight alongside them. The antagonistic witches are also used for fanservice purpose due to their design.

Luminous Arc: Vanessa - like Claire and the other witches, Vanessa desires to protect the planet from Zehaal. However, her hot blooded nature caused her to disagree with Claire's rather passive plan and she decides to collect the Lapistier by herself, using violence if necessary. Nevertheless, Vanessa is shown to possess morality, saving human from their own destruction as seen with the Eurus Knights event.
