"When did Silvia disappear?"
I rushed to Silvia's room, and halfway there, I hastily asked Lilina.
"I don't know, I really don't," this little girl rarely showed a look of unease and panic on her face, "Suddenly, I realized that Silvia wasn't by my side. I should have been watching her, but... but I don't know since when she wasn't there anymore..."
"Just at this moment, when we might encounter the enemy again at any time, what if she runs into a dangerous place during a battle!" I muttered quietly, and Lilina immediately lowered her head, "Sorry... I... I should have stayed with her the whole time, to watch over her..."
"Silly girl, I'm not blaming you."
