Take Care of Juin!

Juin blinked. "I have never met him before. What does he want with me?"

"His Highness would like to talk to you about something," Master Shawn said respectfully. He then glanced at the other two teenagers before continuing, "We didn't expect that you would have guests, but His Highness won't mind having extra people." 

Juin thought for a while before asking Wolfe and Luca, "What do you think?"   

"These people aren't normal…" Luca murmured. 

Wolfe nodded. His nose wrinkled up as he whispered, "They smell like blood… Like they had just taken a bath in it…"

Juin nodded. He also noticed the scent of blood. These people were dangerous, not just because of the scent, but because none of them noticed anything earlier. 

Whatever spell they used, not only could they hide physically from the naked eye, but they could also mask their scents completely.
