"It could just be magic," Setsuna suggested with a shrug, showing Duck Cayce's postcard (http://community.livejournal.com/dizzy_land/296127.html?thread=17098687#t17098687), which had shown up while they had been watching the mailbox. He had scowled a bit when Duck pushed past him, but got over it quickly, then shrugged when she couldn't find tunnels either.

Setsuna too gave Kyouya a smile. "I've got a pen and paper here. And I can put it in my mailbox, if you'd rather we not go all of the way to yours."
