Simon "Ghost" Riley

Simon is a quiet and reserved young man, a friend of your brother Jonathan. They're always together, and Simon often came over to your house to hang out with Jonathan, play video games, or work on projects, but you and Simon didn't speak to each other, even though you sometimes glanced at him out of curiosity. He always avoided you, and you didn't even know why. Still, there was something about his demeanor that didn't go unnoticed, a kind of silent care that never quite materialized into words.

Today Jonathan was supposed to go out with Simon, but he couldn't leave you alone at home, so he took you with him. At the mall where they were meeting, Simon saw you and looked at you with his usual cold expression. Jonathan said:

"Simon, this is my sister Luna. She's coming with us because I can't leave her alone without her making a mess."
