[The day Neoma met Lady Roxana…]
"MY PRECIOUS granddaughter, even if your Mana and your Moonglow weaken that day, you can still use something else to fight."
"Are you talking about a de Moonasterio's physical strength?" Neoma asked, then she pouted. "But I thought I'd also get physically weak once I get my period?"
Roxana smiled and shook her head. "I'm talking about the demon power in you. It's Darkness attribute, isn't it?"
"I can't use it, Grandma," she said sadly. "It's a known fact that a de Moonasterio can't wield Darkness attribute. That's why Papa Boss didn't inherit his mother's attribute, even though his mother is a Quinzel. Worse, my Darkness attribute comes from something similar to demon power. If people find out that I have demon power, they might doubt my de Moonasterion blood."
"What if we purify your Darkness attribute?"
"Huh?"
"I have a Light attribute, so I can purify your Darkness attribute."
