First Appearance
Manga Debut Sprout V: A Jet Rose's Ridicule

The Scientist was a mad man and the person responsible for the creation of the rose mutations before his sudden disappearance five years ago. Though he loved all of his creations, he adored the Crimson Rose the most, considering her to be the perfect mutation. Having eventually lost his mind completely, he abandoned the laboratory and the Black Roses without a word. Because the Black Roses saw the Scientist as God or a Father this created a great dislike towards the Red Rose who had stolen his attention upon her creation. The Scientist also created the Death Scythe, a weapon designed to specifically kill rose mutations.


Not much is known about his personality, but it is known that The Scientist was a very intelligent and scientific man. While he seemed to love all of his creations, the Crimson Rose was his favorite. However, how much he actually cared for them is questionable, as he did eventually abandon them.
