The next Shin Megami Tensei V demon to appear is a bit of a deep cut.
Turdak will show up in SMT V. While some time passed since Turdak appeared in a numbered SMT game, the character did show up fairly recently worldwide.
Shin Megami Tensei V will come to the Nintendo Switch in Japan on November 11, 2021 and worldwide on November 12, 2021.
