Maria was once just an average but popular sixteen year old schoolgirl who was best friends with Filia, Carol, and Lisa. They all hang out each other's houses, gossiping on their crushes, and having sleepovers. When they each heard about the new Skullgirl, it changes their lives forever. But one day she woke up from her bed to find out that she has a pair of bat-like parasitic wings on her back. She was now playing host to a loyal yet protective Parasite named Lancelot. Learning that her friends' disappearances, Maria and Lancelot set out to find them.
The next day, Maria was at the Madman Café drinking her favorite strawberry soda. Her eyes were open slanted to watch a strange yet familiar girl across from her. When she saw the girl's hair attacking the Medici agent, she realizes that the hair was a parasite and the girl was her lost friend Filia. Before she goes after her, the fat brown-haired man named Lawrence grabbed her arm and pulled her face before she puts her hand on his chest to force him to stop.
"Where are you doing, cutie?" Lawrence asked with a smile. "Let's get a chocolate milkshake together. My treat."
"Sorry, but I'm not interested." Maria replied with a sneer. "Now let me go or my dear friend will have to deal with you himself!"
"And who would that be?" Lawrence asked.
"Me!" Lancelot called.
Suddenly, Lancelot rose out of her back and begin to fire a hail of missiles at Lawrence from its shapeshifting wings. Once Lawrence couldn't get up, Maria ran out of the cafe and found out that Filia was gone. Maria took off her hat and suit to reveal herself wearing a short, white puff sleeved shirt with plaid favy vest bodice and short pleated purple skirt.
"Filia may be gone, but we sure teach that freaky guy a lesson." Maria said with a grin.
"Of course, Madame Maria." Lancelot replied. "No one touches my host. I have my sworn duties to protect you."
"Well, thank you, Lancelot." Maria said with a wink. "Now where is the Skullgirl? I want that Skull Heart to gain my old life again."
"She's at New Meridian and so is Filia." Lancelot reported as he sensed the Skullgirl's location and Filia's parasite Samson. "I can feel them. But for us to make sure, we can find someone who can lead us to them."
"Alright, let's go." Maria smiled.
At Maria's command, Lancelot begin to unflap his wings and letting Maria flew throughout the city.
