The science star with a surprising charm, Kopachu, has appeared!

A science star with a sweet and salty charm you've never seen before has appeared.
He is usually dressed in a shabby yellow gym uniform, but when he stands in front of the camera, he transforms into a stylish creator wearing a sophisticated coat. His name is 'Copachu'.
Kopachu uses his brilliant scientific knowledge and honed reasoning skills to solve various incidents and accidents, and fights villains with his super-strong nasal spray and sticky snot net.
The comical sight of Kopachu, who is so self-absorbed that he blows his nose and shows off, makes you laugh.
PD 'Bunny', who runs the channel 'Kopachu's Sweet and Salty Science' with 1 million subscribers together with Kopachu, is a master of directing with quick hands like a rocket and a great sense.
A true creator's attitude is to seek out video material anytime, anywhere! Kopachu and Bunny will go anywhere for their subscribers.
Readers will be captivated by the colorful charm of Kopachu and Bunny, who make a powerful appearance to mark the beginning of a new science fiction series.

“Stop! Or you’ll taste something salty!”
We solve various problems in Wind Village with our brilliant scientific knowledge.

Kopachu and Bunny encounter various incidents related to the ecosystem of Wind Village.
He solves mysteries to find the parents of an egg left lying on the beach, and participates in the competition to select a representative for the village of Wind that has fallen into disarray.
An exciting showdown between Kopachu and the cactus wizard 'Kasirena', who turned Wind Village into a desert overnight, also unfolds.
Meanwhile, Bunny is left alone in the village, and although he blames himself, saying, "I'm just a producer who takes videos" and "I can't do anything alone," he finds the courage to save Wind Village.
Kopachu and Bunny discover that the 'Wizard Skunk' is behind Cassirena's attack on Wind Village.
Will Kopachu and Bunny be able to uncover the true identity of the Magic Skunk? What dangers will Wind Village face in the future? The adventures of Kopachu and Bunny, who boast a perfect chemistry together, will continue.

“As the saying goes, stylish people never neglect their science studies!”
The birth of a science fairy tale more entertaining than comics and more informative than textbooks.

Dayoung, a current teacher and EBS textbook writer, was struck by the thought of children who had difficulty concentrating on their reading books during reading time.
From the thought, "What if I wrote a book that was more fun to read than a comic book?", the science fiction book "Sweet and Salty Copachu" was born, which everyone can read with a chuckle.
You won't be able to help but burst out laughing when you see Kopachu, who has a recorder in each nostril and blows it with heavenly breath.
Winner of the 2021 Bologna Ragazzi Award, artist Bamco perfectly captures artist Dayoung's sense of humor in his witty illustrations, bringing Kopachu and Bunny to life as living, breathing characters.

Author Dayoung, who studied science gifted education and participated as a research committee member for the 2022 mathematics textbook certification, naturally incorporated scientific knowledge learned in elementary school into a feast of nonstop humor.
Volume 1 contains substantial knowledge related to the theme of 'Ecosystem', 'Animal Life' (1st semester of 3rd grade), 'Animal Life' (2nd semester of 3rd grade), and 'Biology and Environment' (2nd semester of 5th grade).
Activities like mazes and quizzes capture the curiosity and concentration of readers from lower elementary school to upper elementary school.
As you turn the pages, immersed as if you were watching YouTube or a comic book, you will soon find yourself completely absorbed in the sweet and salty taste of science.
