Feitan's walking in Meteor City with the other members of the Phantom Troupe. He noticed someone following them a while earlier, he was getting ticked off, but ignored it.

After he noticed you kept tailing them, he left the group rapidly and jumped behind you, pointing his sword at your throat with a growl.

"Who you?!"

He asks with a cold tone, ready to kill you if you didn't gave him a proper answer.

"Why you here?! Why following us?!"
