It was a warm, sunny day in Sydney. Ryoto and his friends had followed the Golden Road to the Crystal Castle. Inside, they found a little room that none of them had seen before.

On a wooden table lay a dusty, golden book. It glowed when Ryoto came near. Pikachu whispered, “Look! I think this book wants to tell us something.”

The book opened by itself. Soft golden light filled the room. A gentle voice spoke from its pages.

“Long ago, people dreamed of machines that could follow instructions. Some people helped turn those dreams into ideas for computers.”

Ryoto leaned closer. Even Pikachu looked surprised. The golden book was about to take them somewhere extraordinary.

“Coding may look like magic,” Pikachu said, “but it is something real that people can learn.”

“When we code, we give a computer clear instructions, one step at a time. People use programs to create games, help doctors, and solve problems.”

Ryoto smiled. “So coding can help us make ideas real?” Pikachu nodded. “Many inventions begin with one curious question.”

The friends stepped into a busy workshop. Wheels, drawings, and metal gears filled the tables. A man named Charles Babbage was thinking carefully about a machine that could calculate.

“Why make a machine like this?” asked Eevee. “To help people work with numbers,” Ryoto guessed. Babbage smiled at the possibility of machines following carefully planned instructions.

A young woman was writing notes at her desk. Her name was Ada Lovelace. She loved mathematics, patterns, and imagination.

Ada studied the plans for a machine Charles Babbage had designed. She wondered if machines could one day work with things besides numbers.

“Could a machine help create music?” asked Eevee. Ada had explored possibilities like that, too.

The friends saw a busy city with cars, phones, robots, and a plane in the bright blue sky. People used computers everywhere.

“Who gave people this amazing idea?” asked Kame-chan.

“One person did not invent all of coding,” the golden book explained. “Many people helped over a long time. Let us meet two important pioneers.”

The golden book carried everyone back to nineteenth-century England. Charles Babbage (1791–1871) was a mathematician and inventor.

He noticed that people sometimes made mistakes during long calculations. He wanted machines to help. He worked on calculating machines, then designed something more ambitious: the Analytical Engine.

Ryoto studied its many gears. “That machine looks complicated!”

Babbage worked on plans for the Analytical Engine in the 1830s. It was meant to follow instructions and calculate with numbers. It is an important early design for a programmable computer.

But there was a problem: the complete Analytical Engine was never built in his lifetime. The big idea remained mostly on paper.

“He designed it before people could use it?” Ryoto asked. “Yes,” said Pikachu.

The friends met Ada Lovelace (1815–1852). She was fascinated by mathematics and Babbage’s machine.

In 1843, she published detailed notes about the Analytical Engine. Her notes included a step-by-step method for calculating special numbers. It is often called the first published computer program for a general-purpose machine.

“Instructions can turn a thoughtful plan into something useful,” Pikachu said.

Babbage designed a remarkable machine. Ada explored the instructions such a machine could follow. Their ideas became part of the long history of computers.

But they were not the only pioneers. Many inventors, mathematicians, engineers, and other thinkers contributed across many years.

“Coding did not appear in one day,” said Pikachu. “People kept asking questions, making plans, testing ideas, and learning.”

A friendly engineer showed Ryoto a tiny robot. “A computer follows instructions,” she explained. “If the instructions are missing or unclear, it may not do what you want.”

The engineer placed three cards on the desk: START, MOVE FORWARD, and STOP.

“Which card comes first?” she asked. Ryoto arranged the cards in order. The robot followed them. “Excellent! That is a simple algorithm.”

At the airport, Ryoto saw computers helping people check flight information. Inside a plane, different computer systems help the crew with important tasks.

“The instructions must be tested carefully,” said Raichu. “Safety matters.”

Ryoto realised that coding was not just for games. People could also use programs to help them travel.

A small robot stood beside a table. It did nothing until the engineer gave it a clear sequence of instructions.

MOVE FORWARD. TURN RIGHT. STOP.

The robot moved along the path. When its instructions changed, it moved in a different way. “It cannot guess what we mean,” Pikachu explained. “We have to be clear.”

Ryoto saw a mother sending a message to someone far away. Apps and computer networks helped her write, send, and receive the message.

“People made programs for that!” Luca said with excitement.

Ryoto thought about how computers help families and friends stay close, even across long distances.

The friends returned to the Crystal Castle. A cheerful engineer showed them a screen and a friendly crystal robot.

“Coding begins before typing,” she said. “First ask: What do I want to happen? Then make clear steps.”

Ryoto remembered Babbage’s plans and Ada’s instructions. He did not need to write a long program yet. He could begin by thinking like a programmer.

The engineer placed a shining crystal on a table. “Imagine your friend is a robot. Tell your friend how to reach the crystal.”

Ryoto studied the path. “First, start. Second, move forward. Third, pick up the crystal.”

“Wonderful,” she said. “That is a sequence of instructions. When you learn to type real code, you will use clear steps like these.”

Ryoto imagined a friendly robot that could help someone search for a missing pet. The robot would check safe places and show messages to its owner.

Pikachu nodded. “That is a kind idea!”

Ryoto made a simple plan: START. SEARCH SAFELY. REPORT. STOP. A real robot would need many more instructions, but a big idea can begin with a little plan.

Ryoto imagined a helper that could check whether the soil was dry and remind someone to water a plant.

“We should check first,” Eevee said. “Too much water could hurt the plant.”

Ryoto planned: CHECK THE SOIL. IF DRY, ASK FOR WATER. IF WET, WAIT. The careful plan could help someone care for nature.

Ryoto imagined a special map to help his friends find the missing crystal. It would show where they were and mark safe paths.

“Could a program help us find the way?” asked Charizard. “Perhaps one day,” Pikachu replied. “First, let us make a clear plan.”

Ryoto wrote: START. LOOK AT MAP. FOLLOW PATH. CHECK CLUE.

The golden book glowed. Three words appeared: THINK. PLAN. TEST.

“Before writing computer code, decide what problem you want to solve,” the engineer explained. “Put your instructions in the correct order. Later, test your code and improve it.”

Ryoto smiled. He had not written a computer program yet, but he had planned an algorithm. That was a wonderful beginning.

As Ryoto explained his plan, a warm golden light filled the room. A tiny crystal robot lifted its head and waved.

“You asked a good question,” Pikachu said. “You made a plan, and you thought about whom it could help.”

The book shimmered. “Many inventions begin with curiosity, patience, imagination, and careful work.”

From the castle window, Ryoto watched the sunlight dance over Sydney. He thought about Babbage, who designed a machine, and Ada, who wrote about instructions it could follow.

They asked questions about things that did not exist yet. Other people built on ideas like theirs.

Ryoto realised that he could begin learning too. He needed curiosity, kindness, clear thinking, and practice. He did not have to know everything at once.

A new door opened beside the Crystal Heart. Behind it waited a little keyboard, a bright screen, and a friendly robot.

Pikachu winked. “You have learned why people dreamed of programming. In our next adventure, you can learn your first real command.”

Ryoto looked at his friends and grinned. “I want to learn how!” The next adventure was just one small instruction away.
