The confusion lasted only briefly before Lucy understood what was happening, more or less.
The puzzled and cold expression on Arthur's face was enough proof to explain his current actions, which were that of an amnesiac person.
She stood rooted to her place and didn't try anything that may startle the man. Her usually emotionless expression melted and was replaced by a gentle one coupled with a soft, beautiful smile.
"What do you remember?"
In response, Arthur backed away until his body was glued to the wall, his hands still holding Makaze and pointing it at Lucy.
Seeing his clear hesitation, Lucy raised her hands innocently and added,
"Don't worry, I'm here to help. Please tell me what you remember?"
