[mizuki-7]

Actually people don't give a lot of credit to her earliest vocals I mean 98/99 I know that she was singing abnormally high but most of her lives in 99 were pitch perfect and crystal clear it seemed so effortlessly to reach the higher register for her ... of course that was not really the case because it was not her natural tone nonetheless in comparaison her vocal the year after
(2000) sounded way more nasal and scratchy.
2003 2004 were amazing though such a shame if only she was able to maintain this vocal quality things would be so different.
