As a premium channel AT-X is also known for showing uncensored versions of several anime like Fight Ippatsu! Jūden-chan!!, Amaenaideyo!!, Girls Bravo, Elfen Lied, Mahoromatic and High School DxD which would normally get censored on TV-stations like TV-Tokyo because of the large amount of nudity and other factors.
