According to Baidu Encyclopedia, the humanoid computer angel heart is not butter. The humanoid computer Heart of an Angel is a Japanese cartoon, which mainly tells the story of an ordinary young man, Bensu and Hideki, who has an expressionless girl and accidentally meets a humanoid computer entity called "Chobits". Although this cartoon involves some sci-fi elements, it is a relatively warm cartoon work as a whole, and has nothing to do with butter (that is, pornography).
