Yoshiki Nakamura is one of my favorite mangakas, hands down.
I love that she is not afraid to change audiences and genres. Her heroines are consistently interesting and refreshing and her stories are consistently deeper than just the surface. I love the psychological aspects and darkness she works into her plots.
I first fell in love with "Tokyo Crazy Paradise" (also known as "Kurepara"). My current craze is "Skip Beat!". I have also enjoyed "Dramatic Love Album" and "Blue Wars", though not as... obsessively as I have enjoyed the others.
Though I am uniting them under the name of the creator, I will keep my categories separated to avoid confusion.
Happily Ever After Never Happens ([post] Kyoko/Shotaru Fuwa) Kyoko just found out Sho was using her. She lays awake that night after changing everything about herself, thinking about how she's never been fairy-tale material, anyway, despite how much she loved them.
Tokyo Crazy Paradise
Aftermath Universe which follows the end of Tokyo Crazy Paradise and includes Asago's wedding, Ryuji and Tsucasa's life together, Tsucasa's new friend Aoi who has secrets of her own, and Tsucasa's first pregnancy --oh, and Tsucasa and Ryou's wedding after he finds out she's pregnant.
