Recently Natalie, a Japanese news entertainment site, set up a Q&A with Perfume where fans could tweet their questions. I'd like to bring your attention to question 17.
母校アクターズスクール広島の後輩達が近年様々な場所に登場して来ています。その内幾人かとは共演もしましたが、彼女達と何か交流はありましたか？#ナタリーPerfume質問企画 #prfmQ17. Over the past few years, your juniors from your alma mater, Actors School Hiroshima, have started popping up at all sorts of places. Have you ever appeared together with any of those girls, and how do you interact with them? #ナタリーPerfume質問企画 #prfm

Probably the other prolific Actors School Hiroshima alumnus that idol fans would be familiar with would be ex-Sakura Gakuin member Nakamoto Suzuka, perhaps more familiar as SU-METAL of BABYMETAL fame.
