First of all, who will be the first person in the series to become three-dimensional? I had a lot of trouble...I'm attached to all the characters, but I decided to make ``Yagiri'' the most popular character by a narrow margin first. It took half a year to release the prototype. From there, it took another half a year to sell it, and after about a year in total, we were able to deliver it to everyone. Of course, I wanted to make all the characters three-dimensional at the same time, but if I started working on it all at once, it would take an enormous amount of time, two or three years later, before I could make an announcement. Characters other than Yagiri will continue to be made into three-dimensional characters in the second and third editions.
