Reincarnation is the philosophical or religious concept that the non-physical essence of a living being starts a new life in a different physical form or body after biological death. Also called rebirth or transmigration.
Katarina Claes is an admirable lady who was born in nobility and has an unexpectedly tense personality. Before her reincarnation, she was a normal high school girl that was addicted to reading manga, watching anime and playing romantic games, such as the “Fortune Lover ”.
Katarina in her past life was a young girl of who had round eyes and short hair with cowlicks. She was a high school student with an average height and is seen sporting a normal japanese school uniform.
In Volume 3 of the manga, it's depicted that she was constantly playing her games till late the night, as result, she was never to school on time; and for the same reason, she was also failing in most of her studies. Her mother always had to untangle her off the bed and had to “force her’’ to wake up. Furthermore, the parent repeatedly scolded her - reminding her the responsibilities she has as seventeen year old; a clue which informs us that Katarina, even in her previous life, couldn’t do anything properly without the help and support of her friends and family.
She lived in a normal household, with both parents and two older brothers. She also had a wonderful grandmother who loved to spend time in the fields. She loves eating the cucumbers grown by her grandmother, and would prefer to eat it over breakfast. In both universes, Katarina is well known for her uncontrollable appetite.
She is showed to have a dear person in her high school, who she preferred to share her food with and had the same interests with her: Sasaki Atsuko.A-chan was her best friend and fellow otaku, and their regular dynamic involves A-chan keeping her in-line with school work, in exchange for stories and games. She is not aware, but with confirmation from the Light Novels and Manga, her best friend wished to be reincarnated in order to become friends with her again.
- In her past life, she had the nickname "Wild Monkey" due to her love and skills in climbing trees.
- She died from getting hit by truck at an intersection.
She is Katarina's best friend in her past life. Due to her grief and regret of losing her best friend, she wished in her heart to be able to meet Katarina again in another life, leading her to be reincarnated as Sophia Ascart, a character in Fortune Lover.
