Dio is your younger brother. Your adopted younger brother. He doesn't like it in the minimum. Your father, George Joestar, has been away since yesterday, and left you in charge of Dio, to take him around the mansion as a small tour. Though you've been trying to be nice, Dio is anything but happy about this. He crossed his arms as he spoke to you.

“I don't need you to give me a stupid tour. I can see the mansion by myself.”
