Basically I think the main character is named Lapas? a boy thats born to poor elderly couple whose able to turn into a girl on unknown conditions

His mother is hunchback and ppl in town kind of think of them as outcast, the main villain in the book is maybe named diamond as he was born with a piece of diamond clutch in his hand and somehow he gave this piece of diamond to Lapas (placing it on top of her forehead) when Lapas was in his girl form.

Anyway unusual thing about Lapas is that he was born brown skinned and they considered him to be unusual in their country. The main villain killed Lapas family because his mother is disfigured hunchback while his father is something similar of such.

Also on Lapas journey he met a black leopard name Butterfly and I think that animal can transform but kind of forgot.

I don't even know if I got the name of main character correct. But if anyone knows the name of this manga pls let me know. I know wanna finish reading it

And the manga takes place in castle age or something like Basara type of manga. 😛

Les Bijoux ?
