The anime character in question would be Mikuru Asahina from The Melancholy of Haruhi Suzumiya, and the original blog which reported this notes “two significant problems with his wish: first, Japan doesn’t allow polygamy, so only one person can marry each anime character; also, Japan gives taxes breaks to married couples, which means people who married anime characters would receive an unfair tax benefit.”
Topless Robot adds “The problem of these people being f***ing crazy is not listed, but I’m going to assume it’s unspoken.”
And I’m compelled to add, “isn’t she too young to marry, anyway?”
Assuming this is at all true. As TR notes, it’s a little difficult to verify for one’s self.
