Sadly...there was an error.
There was a problem getting the anime information from the database. Basically, the website tried and failed to get the anime's information harder than Subaru dropped kicked Rem's feelings when he told her he loved Emilia after the most heartfelt confession ever. This can happen when the internet does funny things, or the database gets a little too excited.
Stop being dumb and realize that Rem is best girl. This error can generally be cleared up by trying to reload the page you were on. If it continues, it's possible the url may not be correct, so try checking that. Also...who is Rem?
I apologize for the inconvenience.
