Kanoko Himemiya
About
Half-sister of Mayu Himemiya. She wants nothing more than to live an ordinary life and secretly keep on helping out Mayu to rise to stardom.
At first, she thinks nothing much of the butterfly-shaped birthmark on her finger but as Tsubame, most popular boy in school, approaches her with the story she is his destined love from long time ago, she gets dragged into discovering more and more about their past lives and the past lives of many others with the same mark.
She too is a reincarnation of Agemaki, but from a different time, thus not being the Agemaki Tsubame searched for.
Despite not liking him at first, they grow close and start dating as time goes on.
