Yuki Kaji has always been passionate about his character as a voice actor. Starting in 2004, Kaji is most famous for his roles in Guilty Crown, Tokyo Ghoul, and Attack on Titan. Last year, Kaji announced his newest project, Soyogi Fractal, featuring a vocaloid-like character from another world. His purpose? To serve as an "immortalized" voice bank for voice actors, as they grow and their voices change (with permission, of course!). The program will be made using CeVIO AI, a software similar to Vocaloid that utilizes both singing and talking from voice banks, that can be used freely.
