Knives went into this smaller room and went directly to the door to the kitchen. Subaru had said it would need to be broken down. He examined the door with his flashlight and then glanced at the human to make sure that the boy wasn't standing right behind him and in the way.
He stepped back and kicked hard against the door. It didn't move, but he wasn't about to give up. He gave it another kick, and another. His leg started to protest from the strain, but he ignored it. Finally the door budged very slightly.
Knives paused and sighed.
This was going to take a while.
