"Impressive. So, just be quiet." In an exhibition tracing the trajectory of Mr. Yasumichi Oka's career, I came across a line from a Fuji Television commercial that aired thirty years ago, and it left me with a strange sense of freshness. There are many righteous people. There are many angry people. The volume of sharp, logical arguments that people want to convey in today's society is significant, and it feels uncomfortable, almost like sleeping under an elevated highway. When it becomes a social issue, this discomfort becomes more pronounced. People often use it as a disclaimer to say what they want without facing any consequences, yet it feels like a sensitive topic that can easily backfire if touched upon. I met Mr. Oguni during the COVID-19 pandemic, and his attempts to address issues like the shortage of masks and welfare were right in the heart of such social problems. However, the light-hearted atmosphere of his team and the comical name gave a refreshing sense of excitement, like something one would experience at a school festival. Even though I joined in the middle of the process, I found myself enjoying it and ended up pulling an all-nighter to work on the design. Looking back, I think I was like a solitary figure, shedding my coat in the light of the sun. Now, I have the opportunity to create a book with Mr. Oguni, and I do a little dance of joy while reading the manuscript. The book gives the feeling of having a casual chat with Mr. Oguni, as he stands nearby, chuckling softly. It's simple and exciting, and I even found some areas where I could improve. It's the kind of book I want to keep at home and open occasionally. "No matter how important it is, if it doesn't get conveyed, it doesn't exist." This book is like a dictionary that cultivates the brain to make things understood, a gentle and inviting sun that shines on everyone. It's bright and enjoyable. It's not about studying, and it's not forced. There's no need for definitive answers. In this era of loud voices where being correct is emphasized, I hope this book finds its way to those who need it. I also hope it can become a charm, continuously protecting and comforting them in a corner of their homes. With these thoughts in mind, I considered the form of this book.

Mr. Oguni, resembling the sun, generates a collection of projects that transform even weighty social issues into enjoyable and positive endeavors. These sun-like initiatives, familiar to everyone and easily comprehensible at a glance, have been represented through a straightforward and iconic "Nico-chan" mark, creating a design that is easily recognizable.
