Kubota Makoto's phantom unpublished work has been made into an e-book! A young man, TAKAO, was forced by his mother to wear a ring that said, "I have the power to destroy the world." I try to let go of it right away, but I can't throw it away because there's something in my way! On the other hand, a group of demon lords, who are planning to recapture the ring, aim for the "promised land" and travel aimlessly. What will happen to the end of the world!? Ironically Delisted
