That's a concerning question to pose, but I don't think anyone can answer that. Age is treated quite vaguely when it comes to Servants, and their apparent age often doesn't match their actual age. On top of that, all of the information we could use from the Servant Universe is even vaguer. The best you can do is just guess.

Going off of her stage 2 Ascension and that she's roommates with MHX, we can assume she's in high school, so she's at least between 15 and 18. If we assume she's the same age as MHX, we can assume she's somewhere between 16 and 18, since MHXX is just MHX who got a job "2 seasons later," referring to the two years since her debut.

That is also assuming the Servant Universe doesn't let minors get jobs.
