Upon finding out that his magic circle design was used in the seventh episode of No Game No Life, Japanese illustrator Ikkakujyu complains about the plagiarism act to the TV anime producers via Twitter. The staff has acknowledged their fault and apologised to the original owner of the design.
A written apology was posted on the TV anime’s official website. According to the production staff, they were supposed to use the illustration as a guide but ended up copying exactly as it is.
Ikkakujyu has accepted the apology and is expecting revisions in the Blu-ray and DVD releases.
