And, I also think Sato-san's words are amazing, to the point that one day I'd like her to write some sort of poem collection, and make it into a book. If Sato-san were to release a book, I'd definitely buy many copies (laugh).

  • Karin Miyamoto said on the show Idol Moiccho that Masaki always says "I can't do it", but when things begin, she suddenly changes like someone else and works it out. Karin thinks of herself as a hard worker who can achieve only by practice, while Masaki is gifted by nature. So "I want to beat her gifted talent with my effort." The host (known as Gurasu-san, a big fan of Masaki as well) says Masaki is in some respects a tensai (genius) and Karin agrees on it.[16]
  • Lyricist and Musical teacher Niira Etsuko [17] told in a Youtube video[18] the behind story about Princess Margaret song in LILIUM. According to her, the arrangement of the song is mostly done by Masaki. Original demo was like 1:15~25, which Masaki changed to 1:26~35. Niira says Masaki is genius and you can't easily find someone like Maa in Japan. Masaki was scolded for her too much arrangement, but Niira says it's her fault because she's the one who approved it. And lastly she says that changing other's work to the extent that you are scolded for that is amazing and that musically Masaki hit the nail on the head. "From the point of view of normal Japanese woman or their peace-at-any-price principle, Maachan is the one who causes trouble." “I can see why she likes Reina” she says with a laugh.
  • AKB48 superstar Sashihara Rino is a big fan of hers [19][20][21]. Ito Chiyuri (Team Syachihoko) and LingLing (BiSH) are confessed wotas of Masaki as well [22][23]
