The evidence cited is: 1, and personal information is completely unknown, only one is from Osaka. As for how old I am, what articles I have written before, what contribution activities I have had, where I graduated, my blog and interviews with the author, I have no information. 2. As the original author, I don't seem to care about the changes of the animated version at all, because the blog Twitter didn't publish anything, and naturally I didn't feel any opinions.
