The romanization we at Doremi used for the name "HadzukiI" was due to how her name is pronounced in Japanese. The translator for the earliest episodes, Neclos, spelled it that admittedly unusual way, and we chose to maintain his spelling of her name after he disappeared in May 2006, leaving that series stalled midway into the first season. The series remained stalled until I found a Chinese translation that allowed another translator to take over. We used that 2-step translation process (Japanese-Chinese-English), double-checking it against the Japanese audio, to complete that season while he was studying Japanese. There are two kana that have been given the romanization of "zu" in Hiragana, - the "unvoiced" one 「ず」 (vocal cords not used) at the "zu", position - the "voiced" one 「づ」 (vocal cords are used, making it sound "dzu") at the "du" position. Hadzuki's name (「はづき」 from Toei's seiyuu credits) uses the latter.

Well aware of the history behind the translation and I still want to thank you lot for everything regarding the series. However, this main intent behind the release was not the Hazuki change but rather replacing something that was added by those who put out the 720p release with what was in the original D-F sub script for this episode

Not a bad job, but the subtitle timing wound up getting out of sync with the corresponding audio in several places.

I made no other edits to the sub apart from what I mentioned so that's probably why there's the timing errors.
