Kazuo walked towards the door, with a piece of his Death Note in his left hand and a pen in the right hand. "Kazuo-kun, be careful" said PIPOr, as Kazuo opened the door. There was a person standing at the door, but they were wearing a mask that covered their face. The person was slouching, similarly to how Ryuta always did.

"Damn it! A mask, I can't see the name or face. They're slouching like Ryuta, not many people do. That might be important, seeing as how Ryuta apparently slouches the same way L did" thought Kazuo. The person handed Kazuo a piece of paper. "Good luck, Kazuo Solius. Don't show this to Z, it is meant only for you, he will recieve his later" said the person as they walked away. Kazuo looked at the paper.

"Kazuo-kun what is it?" asked PIPOr. "It's a puzzle" said Kazuo. "How do you know that Kazuo? It looks like a letter from here" said Gizou. "I'm sure it's a puzzle, it's written the same way the notes were" said Kazuo. "So that person was this BB2 person you're looking for" said Gizou. "Maybe not, if he has a Death Note he could just control someone to do this. Whoever they were, they made sure I could figure out it's from BB2" said Kazuo.

"How Kazuo-kun?" asked PIPOr. "The note said 'I am L. At least I was', they slouched like L did, apparently, to let me know it's from BB2. They way the note was written backs this up. The slouching was meant for me to just assume that that was BB2" said Kazuo. "I see, in that case he can kill you any time" said Gizou. "Yes, he's aware of the rules of the Death Note and probably has the eyes" said Kazuo.

What will you do?

Assume it's a trap from Z and that he now knows you're Kira
