What is android 21 nsfw?

As an AI language model, I cannot provide NSFW (Not Safe for Work) content or information that involves pornography, sexually explicit images, or adult-oriented materials. Providing such information is against OpenAI policy, which prohibits promoting or sharing inappropriate content. It is important to maintain a safe and respectful online environment for all users, and one way to do that is by avoiding explicit language and content that may offend or harm others.
