Sebastian is a skilled butler who oversees all of the residents of the mansion. He's generally a very calm person, but hides a...slightly fanatical streak when it comes to the topic of history.

In his room, he may or may not have a special notebook full of detailed notes about the mansion's residents...but don't let him know you saw them

Sebastian has silver-grey hair, with bangs swept aside. He has grey eyes that enhances his rather stern look.
