"Hn. Yeah, you're right. We need to all be together for this. Says to meet in the warehouse district. How about we meet-"
Kaito gives Nakahiro a street intersection that's not too far from the warehouse district, that ought to let them all gather and plan before heading in.
"I'll get Sora and Izumi up to speed. See you in a couple of minutes."
He hangs up and turns to the others.
"Nakahiro's group found a note. It said "If you want to see them again, meet in the warehouse district at noon."; we're going to meet up with all the others at that address before we head in. Hopefully we can come up with something to help us spring a trap on the kidnapper. Since this whole thing stinks of "giant trap"."
