Her call and response during concerts begins with "Chikyuu no minna, tadaima!" (lit. Everyone on Earth, I'm back!), to which the audience replies "Okaeri!" (lit. Welcome back!). She then says, "Uchuu ni todoku kurai ookina koe wo kikasete kudasai! Se~no!" (lit. Please let me hear your voice that's loud enough to reach outer space! Ready~?), and the audience replies "Ayumu!" She then finishes with "Arigato gozaimasu. Uchuu ichi shiawase desu!" (lit. Thank you so much, that made me the happiest girl in the whole universe!).
Her call-and-response is a reference to Choboraunyopomi's 4-koma manga where Ayumu, as part of the Famitsu group, went to Mars and was popular as a school idol there.
Her image color during concerts is pink.
