Oshima Toshinobu was a renowned businessperson who had published a lot of books. Tamura, the main character of this story, attended a seminar held by Oshima and met a woman named Sakamoto. Through Sakamoto, Tamura gradually came to know what Oshima was like. In Japan, there are many cultic groups, and though this story is a fiction, you will be able to catch a glimpse of such groups through reading it. I first wrote this story in Japanese and translated it into English.
