Cleaning was done periodically by the female knight who had messed up Arthur's shop. The dust flying from the wooden box was immediately swept and removed through the front door.
Seeing the messy condition of his shop, Arthur could only sit silently and receive a small massage from Yuuki who also relaxed while watching the female knight who was cleaning the shop.
"They look like troubled female knights, Master Arthur," said Yuuki in between her small massages.
"Yes, that's right. They are indeed troubled female knights. It is not uncommon for Rei to have to work gently when dealing with their mistakes and carelessness. An example is like now," said Arthur who relief himself when his small shop was almost destroyed by the attack of dust and fragments of wooden boxes that destroyed the floor of his shop.
