Hiddenite is one of the Neo Shitennou, the general corps that appears in the Sailor Moon stage musicals. He stands in the position occupied by Nephrite elsewhere in the series.
A humanoid man, Hiddenite is designed to look strikingly close to Nephrite, whose role he mirrors on stage. His name traces back to hiddenite, a variety of the mineral spodumene, and he goes by the human name Hideo Yoruno as well.
Little is set down about his character apart from where his allegiance falls. He stands with Queen Beryl and the other Neo Shitennou, one of the generals tying the Golden Kingdom to the Dark Kingdom.
