The official website for the B Gata H Kei television anime series has posted an "important notice" from the anime's production committee about multiple threatening letters that the anime's studio and writers have received. The letters ask for changes in the anime's content and presentation, and threaten the studio and writers with harm if they do not respond.

The website notice points out that the anime's content and presentation are established by the production committee as a group, and are not the sole responsibility of the studio or the writers. The notice added that the production committee is not responding to the letters' demands and have contacted the police about the matter.
