The first time she took the number one spot was after the release of her first album, "apple symphony" , on the 4/17 ranking, which took place three months after the album was already released. It seems that the album release put a spotlight on "Jiku Tours" , and the song took #1 during the weekly USEN HIT Anime Ranking (A-31 Channel) for the 5/1, 6/5, and 6/12 ranking charts, for a total of four times at the top.
In the past, Yuzu's "REASON" (theme song for The Movie:HUNTER x HUNTER Phantom Rouge）broke the record and stayed at #1 from January 23-February 13, 2013 , four weeks in a row, however, Yuzu and Ayana Taketatsu are the only two artists who have ever taken the top spot for a total of four times. Those who have come close include Ikimono-gakari's "Haru Uta" （theme song for Detective Conan: The Eleventh Striker）which was #1 for three weeks in a row from 4/18-5/2 of 2012; Utada Hikaru’s "Sakura Nagashi" （theme song for Evangelion: 3.0 You Can (Not) Redo）which placed #1 for a total of three times during the December 5, 2012, December 26, 2012, and January 16, 2013 ranking charts. Among these, Ayana Taketatsu is the only one whose song has non-exclusive rights.
