ANN has it listed under "(Le) Portrait de Petit Cossette (OAV)" and "Cossette no Shouzou (OAV)". Since "le" (and/or "la") is "the" in French, you skip it when listing by alphabet. So it is categorized under "P". The odd thing is that the title that is on the top of the page is "Petite Cossette (OAV)", but there is no listing under that particular variation of the title.HeavyMetal wrote:Cossette go by another name? I could not find it on Anime News Network.
Anyways, I'm not sure these will fit your bill, but I'll throw in Lunar Legend Tsukihime and Vampire Princess Miyu (OAV). There is also a hard to find VPM TV series out there that I've never personally seen.
