-Chapter 1-

Sherlocnyan

"Hiroki is…kidnapped?!" Prof. Layton exclaimed.

"No way!" Luke gasped.

"Unfortunately, it is true…" Sherlocnyan said in depressed tone.

Prof. Layton and Luke were shocked. Not only were they surprised from meeting an actual real yokai in front of them, but also the revelation of horrible news that the professor's old colleague was kidnapped.

"Sherlocnyan, could you explain the whole story?" Prof. Layton asked calmly.

"Certainly. However…" Sherlocnyan looked with curious, yet suspecting eyes. "I'm not quite sure if I should."

"What do you mean by that?" Luke questioned.

"I am not sure if I can trust you both, even though my friend, Hiroki knows you, Professor Layton," Sherlocnyan explained.

"What!? Why? Do you doubt on the professor!?" Luke shouted in anger.

"Now, now, Luke. Calm down," the professor said as he padded the boy on his shoulder. "I understand how you feel, Sherlocnyan. Is there any way I can gain your trust?"

"Well, if you are who you claim to be, I would like to test you here and now…with a puzzle," the cat yokai stated.

"A puzzle?" Prof. Layton repeated as he placed one knuckle on his chin.

"That's right," Sherlocnyan nodded. "Hiroki always said to me that you are famous puzzle solver of all England, so I would like to test you through a subject that you are very knowledgeable on. If you do solve the puzzle I will give you, then I will acknowledge you and you gain my trust."

"Hmmm…" Prof. Layton hummed as he closed his eyes. He reopened it in few seconds later. "Alright then. I accept your test."

"Professor, are you sure about this?" Luke asked.

The wise professor smiled at his worrying assistant. "Do not worry, Luke. You should know more that I've solved many puzzles, some difficult one in the past. Whatever puzzle that Sherlocnyan will give me should not be too challenging."

Luke gave a light smile. "You're right, professor! Good luck."

"Very well, then. Here is a puzzle!" Sherlocnyan started. "There are three sheep, one guard dog, and two wolves. The shepherd wants to cross the river, but his boat can only carry two things at a time. He wants to get all of his sheep and the dog cross over the river to the other side. How many times does it take for him to get all of his sheep and dog to the other side of the river? Also to note, he cannot leave a single sheep alone with the two wolves and one ride consists of one trip."

"Three sheep, one guard dog, and two wolves…." Prof. Layton thought. "Luke, what do you think of this puzzle?"

"Hmmm, I think…oh, I get it!" Luke realized.

"It seems like you already figured out, Luke," the professor chuckled. "Sherlocnyan, I believe we have an answer."

"And what would that be?" He asked.

"That would be 5 times," the professor proposed.

Sherlocnyan gasped with his eyes blank in surprise expression. "What!? How?"

"Care to explain, Luke?" The professor suggested.

"Certainly, Professor!" Luke agreed. "You see, the shepherd can only carry two things on his boat at a time, and he cannot leave a single sheep with the wolves, like you said. He can carry the first sheep with the guard dog on his first, and then the second trip, he can come back with just a guard dog. Then, he can carry one sheep and one of the wolves on his third trip, and leave the guard dog with the last sheep, so that the other wolf won't harm the last sheep. Finally, he come back again with the first wolf on his boat, leaves it, and carries the guard dog and the last sheep with."

"Just as I thought, too. Well done, Luke," professor praised as Luke blushed a bit.

"I can't believe it! You really are DE Professor Hershel Layton!" Sherlocnyan exclaimed. "For that, you both gain my trust!"

"Thank you, Sherlocnyan," Professor Layton said. "Now, would you care to explain what happened to Hiroki?"

"Certainly!" He complied.

Professor Layton and his assistant, Luke joined into discussion with Sherlocnyan as he explained about Hiroki's kidnapping.

"You see, it was about two weeks ago. I was helping Hiroki with his works when one day, he disappeared!" He exclaimed.

"Disappear?" Luke echoed.

"Yes! I looked for him and didn't found him, except this!" Sherlocnyan pulled out a piece of paper out of his pocket. "I found this on his work desk! It was a note from his kidnapper!"

"His kidnappers?" Professor Layton's eyes sparked. "May I see it?"

"Of course." The cat yokai handed him the piece of paper.

"What does it say, Professor?" Luke asked.

"It says here that 'If you want to see your precious human again, help us find what we are looking for that you are looking for!'" Professor Layton said. "What does that mean?"

"I'm afraid that the kidnapper was referring to what Hiroki and I've been researching about," Sherlocnyan said.

"What were you two researching about that these horrible kidnappers wanted?" Luke questioned.

"The legendary, mythical sword…Excalibur!" The boys gasped at what the cat yokai said.

"Excalibur? Do you mean that DE Excalibur from the story of King Arthur?" Luke asked.

"Yes, that is it!" Sherlocnyan shouted as he came close to Luke's face, too close that is.

"Excalibur…" Prof. Layton mumbled as he walked over to his bookshelf and scanned to find one book, which he soon found what he was looking for. "A legendary sword that the young King Arthur obtained from the legendary Maiden of the Lake. It's an old legend, a story that was told through many generations here in England, but why were you and Hiroki researching about it?"

"Well, Hiroki believed that Excalibur relates with his study on yokai," Sherlocnyan said as he got off from Luke's face, with the boy froze in surprise. "But, because of that, Hiroki, my savior, my friend…is nyoonnneee!"

Sherlocnyan cried as snout came out of his nose.

"I see…Very well," Prof. Layton said. "We'll help you, Sherlocnyan!"

"You would?" He asked as he wiped his eyes and snout off from his face.

"Of course! And we will do it by finding the Excalibur," the professor revealed.

"What!?" Both Luke and Sherlocnyan gasped.

"But Professor, that is exactly what the kidnapper wants us to do, according to the note! How would finding a legendary, mythical sword save Mr. Hiroki?" Luke questioned.

"It's true, but if we find the Excalibur, we will find Hiroki. This note and Sherlocnyan's information are the only clues to Hiroki. Whatever the kidnappers are planning, we must find the Excalibur before them," Prof. Layton explained.

"I guess you do have a good point there," Luke agreed. "Alright! It's time for the famous Professor Layton and his trusty number one assistant, Luke on another case of mystery!"

"Oh, thank you so much! You two are such wondrous champs!" Sherlocnyan bowed to them.

"Of course, Sherlocnyan," the professor replied.

"Until we find Hiroki, I will be on your side, assisting you. As I am a great detective yokai, after all," Sherlocnyan said as he took out something else from his pocket. "Also, take this."

Sherlocnyan handed the professor a medal. It showed himself holding magnifying glasses as he looked around for clue.

"What is this?" Prof. Layton asked.

"That's a Yokai Medal!" Sherlocnyan answered. "We, the Yokai, give those medals to human when bond of friendship is made between them. With it, it means that we are now friend."

"I see," Prof. Layton laughed as he smiled. "Very well, then. I will keep it safe."

Professor Layton and Luke joined forces with Sherlocnyan as they looked determined to save Hiroki and find the legendary sword, Excalibur. However, little did they know that they were being spied by a mysterious being outside the window.


Hello, guys! Here is the long awaited, the first official CHAPTER for my Yo-Kai Watch x Professor Layton crossover story!

Sorry that I haven't updated this story like in two months since the last one (and the last chapter was just a prologue). The crossover movie officially begins with this chapter! The reason why it took so long is because I was too busy in other stuff, such as another new story I am writing. I will get the next chapter sooner than two months hopefully.

With that said, I am still accepting any Englandian Yokai OC. Please read the previous chapter, one of them to read the detail about it and follow the exact guideline. For everyone who already submitted one, thank you for all the submission. I will see you all in the next chapter, which will shows Ken, Keita, and their friends exploring London! See you guys then.
