Cross-Dressing Voices: Black☆Star is voiced by Yumiko Kobayashi, a woman. This becomes more evident in his character song, "My Star".
Also he is voiced by a female in the English dub.
You may recognize Crona's voice as Fujioka Haruhi's. But well... we're not sure WHAT Crona is yet, so this trope may not fit. But it might. Maybe not, though. It possibly could—why are you so confusing, Crona!?
This is the Japanese voice actor - Maaya Sakamoto, not Caitlin Glass. (Maxey Whitehead voices Crona in the English dub).
Check this out: Spirit is Tamaki Suoh, Giriko is Kyoya Ootori, Death the Kid is Hikaru Hitachiin, Medusa is Hunny-senpai, Free is Mori-senpai, Kim is Haruhi Fujiioka, Tsubaki is Renge. This is almost the entire main cast of Ouran.
It's by Funimation, who uses like 80% of their entire acting troupe in all of their anime. The same thing can be said for their other shows.
