This blog page is about Shirota-san's interview in the magazine published on August 26. This is only summary of some info and not literal translation.
・The idea of purple costume in LGC was from Jeff.
・Yuzuru was thinking of repeating LGC saying "I'll do it perfectly in the next season!", but Shirota suggested, "You are the champion, so how about the program like the chamipion?", "Good program is still good after having done many times".
・The new costume of Chopin is in "the color of winning".
・Yuzuru really cares about the sound and he sticks to Zimerman's. (he doesn't want others')
・Yuzuru is curious about learning to play the piano after his skating life is finished.
・In the Words this year, Yuzuru was so depressed after the SP. But Shirota encouraged "You have to land the jumps to win!", then Yuzuru changed his mindset quickly and started to calculate BV and he knew he had still chance to win if he landed all the jumps. Shirota said to him she was worried about 3Lz the most, but he said, "I'll be alright, I won't fail!"
・Shirota worries about the sound effect in the venue of Pyeongchang Olympics, she felt there was the gap of the sound depends on the place the skaters stood in the rink. She really hopes it will be fixed in the Olympics.
