The Kira investigation task force numbers approximately six people. Inexplicably, you have commissioned a twenty-two-storey building for the investigation.
Please explain this to me, L. Even if you give every task force member an entire floor to themselves, you still do not need half that many floors. What are you using all that space for? Storing all your lollipops? This has mystified me for years.
In any case, this is where you'll end up working with Light after he loses his memories, although you don't know that yet.
It's also where you'll die, and you definitely don't know that.
On some level, though, you feel a little uneasy here. Maybe you should go somewhere else.
