Hatsune Miku cameo[]
After removing the dream cameos I had to double check the Hatsune Miku one... I couldn't find a license notice anywhere (I also tried checking the manga, but I couldn't find the chapter serving as the basis for the episode, if it even exists... the cameo could be an invention of the anime adaptation anyway as it added various pop culture references) however this site correctly pointed out that the character is voiced by her original voice actress, Saki Fujita, and that she's called "Hatsune Miku" in the cast credits, even being so kind as to provide the screenshot of the credits (her name is fifth from the right).
So, given that they would probably not use the official name for a spoof, and thanks to Ms. Fujita giving legitimacy to the cameo, I assume the appearance is indeed authorized, so I'm leaving it in as type 1.--Kombatgod (talk) 23:21, April 12, 2019 (UTC)
