Fighting bullying using only colors and numbers
An original picture book about the importance of courage.
With vivid colors and simple sentences, one person's courage is expressed.
It makes you feel naturally how much of a change it brings.

There are many books that deal with bullying, but this book is unique in that it addresses the issue using only colors and numbers.
Moreover, it is also attractive that the author subtly incorporates universal lessons into the vivid colors and simple sentences, allowing children to naturally empathize with the book while reading.
Red and blue are both wonderful colors, but their relationship is by no means equal.
Red, who gets angry easily, often harasses the quiet Blue.
Other colors comfort blue, but no one can tell red not to bother blue.
When that happens, 1 appears and says no first.

Through 1, children will learn how important one's courage is and realize how to act.
Moreover, the ending where Red is not chased away but plays as a group is reassuring to children.
Even among us, we often see cases where the 'differences' of each person manifest as 'conflicts' or 'superiorities'.
What can we do in times like these? I hope that the example of 1, who is the first to step forward and say no, will inspire courage in many people.
