Rinne is a classmate of Ichinose Houtarou at Furasu High School. As a student at Furasu, Rinne presents herself as a model student with impeccable grades and manners. However, this is a facade as unbeknownst to many, Rinne is a student attending the secret Alchemist Academy under the mentorship of her teacher, Minato.
Rinne is the daughter of the prodigious alchemist Kudou Fuuga, who vanished 10 years prior the start of the series. Rinne grew to resent her father for stealing the Chemies from the Alchemist Academy prior to his vanishment, whilst having mixed thoughts about the reason behind her father's act.
Rinne uses the AlchemisDriver to transform into Kamen Rider Majade.

Trivia
Renge jokingly calls Rinne "honor student" since Rinne is usually studious and by-the-book, whether as a student in Furasu or in the Alchemist Alchemy.
In her transformation, the Prominence Horn refers to a Solar Prominence and a unicorn's horn, both aspects of the cards she uses to transform.
