Both hizuku_yuuki and hizuki_yuuki appear in wiki with kanji (hiragana) 火月邑姫 (ひづきゆうき) and Cure #20895.

The kanji and romanji on Cure are 火月邑姫 and kiduki_yuki.

ひづきゆうき appears on only on wiki and romanises to hiduki yuuki for me.

Yuuki and yuki are fairly close. I see them used interchangably.

Both 火月 and ひづき romanises to hitsuki for me. I think hizuki or hiduki may be obtained based on the kanji or hiragawa characters used after them. So I think hizuki_yuuki is fairly accurate and hizuku_yuuki is an error. So, I have retagged hizuku_yuuki to hizuki_yuuki.

Please remove the wiki for hizuku_yuuki to eliminate confusion for those who search the kanji.

Aliased and deleted wiki since ひづき is Hizuki.
