'To this end, Arenai Medical Encylopedia was removed under “Article 13, Paragraph 1, Item 1 (stimulation of sexual feelings), Item 2 (inducing roughness & cruelty), and Item 3 (encouraging drug use)”, while Arenai Craft Encylopedia fell victim to Items 1 and 2 as well as worry that it my “hinder healthy growth”.'
