Where is Shiro?

…

Shiro wants to see Ganta! Where is he?

Phone!? Maybe it can tell Shiro where Ganta is!

[What’s that sound? Oh, that’s the sound of Shiro punching a bunch of random numbers on the phone. If she happens to call your house in the process, don’t mind her, she will just keep thinking that sooner or later, she'll reach Ganta's house.]
