Evelynne is a former Magical Girl, as well as Marianne's ex-husband and Isabelle's father. A supremely powerful shapeshifter, she became trapped in male form after being injured in battle with the magico that killed her team mate Claire.
Backstory
Evelynne was formerly a Magical Girl and teammate of Marianne. During a battle against a magico which killed her teammate Claire, she was injured to the point that her magic dissipated, trapping her permanently in a male form.
Eventually, Evelynne and Marianne married. Their two children possessed astonishing fairy magical potential, which Marianne wished to make use of in her crusade against the magicos. Evelynne, however, thought it best to let the children choose their own path in life. She ran off with the two children, intent on keeping them safe from their mother's insanity, but Isabelle eventually wound up once more in Marianne's care.
Evelynne and her other child died in a traffic accident soon after Isabelle's mysterious disappearance, at least according to Olivia who performed the autopsies.
Personality
Evelynne is described first and foremost as a slutty and manipulative nymphomaniac, though the source of this information is Marianne, someone who may hold a grudge against her. During her time as Marianne's teammate, Evelynne was wild and fierce.
Interactions
Evelynne is never actually met in game. All information regarding her comes from conversations with Marianne.
