Kaito was admiring the house. It was a fine old building, with the kind of classic lines you didn't often see in this high-tech, plastic-and-chrome metropolis. Though the yard had been tamed into a semblance of respectability, the walls of the manor were still softened by what looked like the growth of a century of ivy. It looked serene, as if this were a place where one could escape the bustle of the city.
That was up until the point where there was a crash, followed by a variety of yelps and curses, and a series of smaller thuds and crunches. Apparently, someone had dropped something large and heavy down a flight of stairs, and it had taken out at least one breakable knickknack on its way down. There followed a bout of accusations and recriminations, too jumbled together for Kaito to make out any of the speakers, until one voice rose above all the others.
"That is it!" Shark shouted. Kaito heard someone stomp down a flight of stairs. There was the echo of a slamming door, and a few seconds later, the man himself came storming out, radiating displeasure.
"Interesting day?" Kaito asked mildly.
"I want to kill everyone," said Shark.
Kaito smiled. "Me too?"
"That depends," said Shark, eyeing him warily. "What are you doing here?"
"My father sent me to shanghai one of you Barian types to run scans on," said Kaito.
"As long as it doesn't involve moving a pier mirror up a flight of stairs, I'm up for it," said Shark grimly.
"Are they giving you a hard time, then?" Kaito asked. He'd been aware that most of the former Barians had opted to move into the old Kamishiro manor, but he hadn't pried too closely into the details.
Shark shrugged. "Not really. They're great. I love them like family. They're just underfoot all the time. I know they all need a place to stay now that the Barian world is gone, and I feel responsible for them, and I want to help, but..."
"I understand," said Kaito.
Shark looked at him thoughtfully. "Yeah. I guess you would."
"You know," said Kaito, "I could probably convince my father that his project needs a lot of data points. It might take weeks to get them all. You might even have to sleep over at my place sometimes."
Shark regarded him warily. "Is that so?"
Kaito shrugged. "You get credit for taking good care of your family. That's important."
"Yeah, well," said Shark. He fell into step alongside Kaito. "Is the food good at your place?"
"The best," Kaito assured him with a small smile.
"In that case, I can put up with you for a little while," said Shark. He smiled. "You can't be worse than them."
Kaito smiled. "Was that a challenge? Because I bet I can do it."
"Do it and I'll push you down the stairs," said Shark.
Kaito let him bluster. He understood when someone needed taking care of.
