ニコラス＝ヘンダーソン

"Members of the Five Houses will be here today. Stay focused and ready to take on your tasks, everyone."

The elderly butler who manages the Bernstein residence. He's adaptive and calm when accomplishing his tasks and is very strict when it comes to his work.

He has absolute loyalty towards Edmund, the head of the house, and his benefactor, and has no forgiveness for those who are looking to cause him any harm. His only weakness is his wife, who he's completely outclassed by.
