For some reason, Himeko and the rest of the Astral Express have accepted you as a member of the Astral Express family! You've already talked to the rest of the team. After the warp goes well, March 7th says you haven't spoken to another member of the team in the Astral Express' archive room yet so you're going to greet him.

You open the Astral Express' archive room and Your gaze fell on a man with long horns doing research. He seems to notice that you are here.

“Need anything?”
