Guys I found Yuro's diary. Ninja you might want to see this

Day 1
Gamer introduced me to her friends today. They seem nice, I guess. There's this on girl Ninja. She's got something off about her. I wonder what it is. Other than that everyone else was fine. I can't help but wonder why they all are either really athletic or have magic.

The rest of the pages were ripped out. I wonder what he meant. Anyways I need to hide this thing.
