"Yes. That's right..."

An man wearing a black suit, was sitting by his desk as he's having a important discussion with L.

"I'm requesting that you conduct a through top secret probe of all NPA personnel involved in the Kira case, as well as their close friends and families"

"L...Are you suggesting one of them may be Kira?" Steve, the director of FBI ask him, making sure he heard right.

"Yes. In fact, I'm sure of it!!"

"But we're already putting a lot of manpower into this case..." the man trailed off, that they already been pushed to their limit.

"The number of American criminals believed to be Kira's victims is 327. That's by far the most worldwide"

The man stay silence for a moment, then he sighs
"Alright. We'll do you ask" said Steve, accepting his request.

*Unknown Room*
"Thank you"

"And please do the best you can. We have to stop Kira as soon as we can" said L.

"Now pay attention, this is important" he continue to say as the shingami was standing near to Light was, staring ahead.

"Before we tackle more complex quadratic equations, we have to start thinking of large X's value..." tells them.

As Ryuk walked among the students, voice..voice

Eyes trained on something outside, "Now let's apply this concept to our first problem"
