On December 10, 2014, a supporter of politician Daisuke Sakamoto (Party for Japanese Kokoro) dressed as Demon during a public event supporting Sakamoto in the 2014 Japanese general election to represent Hiroshima 7th district. When news of the cosplay spread on the internet and TV, Demon wrote a blog post stating that because it was not made clear that it was a fake, any similar acts in the future would result in legal action. Sakamoto apologized stating that it was a "careless" decision.
