Is There an Error in This Book?

I'm incredibly lucky that my publisher, Pyacchus do such a beautiful job with them. Ultimately, I 100% take responsibility for what is on the inside of the book. With this particular book, just a week ago, I realized that one of the Japanese characters in the book is wrong. And there's only one word out of 50,000 words. But for that moment, I'm just saying with a typo in English.
