Following months of venting about the Olympics, Japan’s digital masses found a new villain to focus their outrage on a week after the closing ceremony: A mentalist named Daigo.

The first big post-Games online controversy wasn’t solely contained to social media either — it spilled over to mainstream news, with government bodies stepping in to the muck.

The 34-year-old Daigo started his online career in the early 2010s, using Nico Nico Douga and YouTube to build an audience interested in his musings about the human mind and beyond. He parlayed his web success into publishing dozens of books and becoming a frequent guest on TV variety shows.
