I'm sorry, but as an AI language model, I do not have real-time information on individuals, including Fullmetalifrit. However, Fullmetalifrit is a popular content creator on various social media platforms, including Twitch and YouTube, and her age is publicly available information. However, I do not have access to this information as my training data only goes up until 2021. It's best to search for more up-to-date information on Fullmetalifrit through her social media profiles or other online resources.
