Chapter 47: The Marriage Registration's Password, Part Two

"Oh, right." Sato recalled. "Miike told me you drove one of the MPD's patrol cars all the way to Yamanashi."

"Yeah." Yumi confirmed. "Chukichi said he was going to be late to some kind of match. Now that I think of it, it might've been a Shogi match. Have you heard of the Tokiwa Hotel?"

"No." Sato admitted.

"Anyway, we made it to the hotel, but Chukichi was panicking because I lost a photo of me that he kept as a good luck charm." Yumi related. "So I sent him off with a kiss."

"Anyway, don't you think it's cold in here?" Haibara wondered, as Conan and Fumio continued agonizing over the code.

"Could you turn on the hear, Hachitsuka-oji-san?" Fumio requested.

"I wish I could." Hachitsuka replied. "But the cooling and heating unit has been broken since yesterday. It doesn't work. Sorry, Fumio-kun, but you'll have to endure the cold."

"Did you come up with this code?" Yumi wondered.

"Yeah, I did." Hachitsuka replied. "Why don't you think so?"

"Because this isn't the original." Yumi replied. "It's a photocopy. I'm saying you probably copied a code someone else wrote down somewhere."

"I guarantee you I wrote that code." Hachitsuka snorted. "I only copied it because I felt like it."

"If you made the code, at least give us a hint." Yumi pressed.

"Even without a hint, if you're prepared to marry Master Taiko, you should be able to solve the code quickly." Hachitsuka scoffed. "If you're prepared to be a true married couple, that is."

A married couple? Conan was stuck by the statement. Wait a minute, that code was in the trash can, wasn't it? Then if we fold that paper into that shape... "Fumio, lend me your ear." he gestured the blond boy closer and whispered something into Fumio's ear.

"Yumi-san, let us borrow that." Fumio snatched the paper away and started working on the paper, folding it into a paper crane.

"That's amazing." Sato gushed after Fumio completed the paper construction. "It spells something. Yumi, enter the eight digit password." she told Yumi after Fumio slid off the chair.

"Those aren't numbers." Ayumi pointed out.

"It's katakana." Mitsuhiko stated.

"It's okay." Haibara assured. "Most adults could decipher an eight digit code from that."

"And the code Fumio-kun showed wasn't the only one." Conan added. "There's a pair."

"Ai-chan was right." Ayumi gaped when Yumi just entered the eight number password. "Yumi-san entered an eight digit number without hesitating."

"But the code was written in katakana." Genta noted.

"Why did those characters appear when you folded the code sheet?" Mitsuhiko wondered. "You didn't get any hints."

"We did get hints." Conan corrected. "The fact that he went out of his way to copy the code sheet and that the sheet was in the trash can were hints."

"Copied?" Mitsuhiko echoed.

"What would have been obvious if he hadn't made a copy?" Conan questioned.

"Like a sketch or whiteout?" Haibara suggested.

"Then, take this sheet I just folded." Fumio showed the other three unfolded paper. "What disappears when a copy is made?"

"It's the ceases." Ayumi exclaimed.

"That's right." Conan confirmed. "If there were ceases on the paper, we would've known right away how to fold the sheet."

"But how were we supposed to know how to fold it without them?" Mitsuhiko asked.

"That's why the sheet was inside the trash can." Conan replied.

"It's an old expression." Fumio started.

"'A crane in the junk heap'." Haibara quoted. "It refers to someone exceptionally talented or beautiful mixed in with a group of unexceptional people."

A junk heap is a place where you dispose your garbage." Conan explained. "Since this code was in the trash can, it means we should fold the code sheet into a crane."

"If you fold the crane with the code facing up..." Fumio used the Shogi board as a work-table and refolded the paper. "As you can see," he held up the paper crane. "It spells the words 'root' and 'five'."

"Root five is the number you square to get five is called the square root of five or root five." Conan explained. "Most middle and high school students are made to memorize the first eight digits."

"Enter another eight digit number?" Yumi exclaimed when the entered password brought her to another password-required screen. "You meant root five isn't the only password?"

"It's okay." Conan assured. "We'll just fold another crane out of the code sheet. The old man gave us another hint when he mentioned married couples. Start by folding it back to this shape with the small overlapping squares." he took the crane from Fumio's hands. "Fold like part like so. Then, you just have to fold a crane again. It should reveal a different word like root five."

"It's not katakana this time." Ayumi blinked, seeing the weird symbols on both sides of the crane.

"The symbol on top of the circle is the square root symbol, though." Fumio pointed. "I think we just need to figure out the number that goes inside the circle."

"But our hint is this strange drawing." Conan sweatdropped.

"Maybe it's a nine." Genta suggested. "If the circle's on top is the moon and the thing underneath is a sake cup, then it could signify moon viewing, right?"

"But the square root of nine is three." Haibara stated. "It's not eight digits."

"My dad always says he wants to enjoy a drink while gazing at the moon." Genta pouted.

I see. Conan grinned. That's it.

"Sonant marks?" Mitsuhiko echoed after Conan explained. "These two dots on the upper right side of the cup are sonant marks?"

"But how does that help you determine the number that goes inside the circle?" Ayumi asked.

"Then, try counting up from one." Fumio suggested. "How do you count fingers?"

"Ippon, nihon, sanbon, yonhon..." Ayumi recited.

"How about mice?" Fumio turned to Genta.

"Ippiki, nihiki, sanbiki, yonhiki..." Genta counted.

"How about beverages?" the question was directed at Mitsuhiko.

"Ippai, nihai, sanbai, yonhai..." Mitsuhiko counted.

"You've figured it out by now, right?" Conan smiled. "When counting objects, which number uses sonant marks?"

"It's three." the other three chorused.

"Apparently, you're supposed to enter root three." Haibara told the two female officers.

"What is this?" Yumi stammered when the screen shimmered to reveal the her live image. "The screen just switched to showing what's being captured by the camera on top of the computer. Where's the envelope?"

"Look closely." Hachitsuka snorted.

"The envelope's in my coat pocket." Yumi gasped, spotting the envelope tucked inside her coat.

"I see." Sato realized what Hachitsuka had done. "When Yumi ran into you in the entryway, you used your pick-pocketing skills to hide the envelope in Yumi's breast pocket."

"Chukichi's marriage registration is mine." Yumi beamed, pulling out the unfilled registration form.

"The championship match is taking place at the Jinya Inn in Kanagawa." Sato referred to the internet news using her phone. "They break for lunch until 1:30, so..."

"I can make it in time if I rush there in a taxi." Yumi grinned. "Someone's calling." she blinked. "It's Chukichi." she recognized the Caller ID. "Chukichi?" she took the call. "I thought you couldn't use your phone right now."

"It's all right." Haneda assured. "The match is already over. You can throw away the envelope. It's meaningless now."

"Oh no!" Mitsuhiko exclaimed, as the news bulletin came in on his phone. "They're reporting online that Master Taiko lost the match."

"Let me see." Sato took the phone. "'Evidently, troubled by something else, Master Taiko made one poor play after another and lost before lunch.'" she read the newsflash. "Apparently, it's true."

"But, Chukichi..." Yumi started.

"Stick to the plan." Haneda insisted. "It was the motto of my brother-in-law, the respectable Shogi player, Haneda Koji. I'm sorry, Yumi-san. Men don't like to go back on their word."

"Really?" Yumi muttered and tore the envelope and the registration form into shreds. "I don't know what you put inside this envelope, but if you've got something to say to me, say it to my face. If you ever get your seven or eight whatevers and become a champion again, I'll hear what you have to say. So, don't let anyone beat you until then, you balding mouse!"

"Yumi, that was awesome." Sato applauded.

"I thought she was Cha-cha, but she was Nene after all." Hachitsuka gaped. "I can see she wears the pants in their relationship."

"Don't you mean Nobunaga, Hachitsuka-oji-san?" Fumio sweatdropped. "I sure hope tou-san and kaa-san aren't as dramatic as these two."
