Mana is a beautiful young woman who bears a strong resemblance to Erina Nakiri except that Mana has thigh-length salmon-pink hair (in contrast to Erina's orange hair) that is tied back on top while the rest is tied at the bottom with two small hair strands hanging in the middle and two medium ones resting on her shoulders, sharp purple-pinkish eyes that has long eyelashes, pink lipstick and small, round eyebrows.
Her first appearance in the anime and manga saw her in a long, possibly traditional Japanese kimono, wearing a dark-colored cardigan and donning a traditional fan.
Mana has a cold demeanor who refuses to show any emotion, even in front of her long-unseen daughter. Moreover, she can be interpreted to have a very stand-out personality (possibly a negative one), to the point that Erina can pin-point the bracket re-setter (Mana herself) just from the placement. She also has been shown to have an obsession towards "Superhuman Abilities," specifically those that Les Cuisiniers Noirs possess (i.e. Asahi Saiba's Cross Knives), despite vehemently denying Erina's God Tongue, referring to that as an unneeded super human ability.
However, Mana can be best described as having a severe culinary obsession, one that seeks to find new forms of food that can satisfy her, with unhealthy levels of fanaticism. So much is her disgust at eating current food that she can no longer eat normally, so she gets her nutrients via IV injections. It is her strong desire to find food that pleases her that made her abandon her daughter.
She seems to feel little if nothing about this, as proven with the fact that she deems Erina as somebody she doesn't need to fulfill her goals.
During the BLUE, after seeing Sōma Yukihira and Erina battle in the final round and seeing how far Soma would go to make Erina say "delicious", regardless of her God Tongue and the enormous difficulty it presents, Mana has since come to realize how important it is to dedicate oneself to making the best food possible for one special person. With that, Mana's goals and personality were shaken to their core and she has since reconciled with her daughter and happily rejoined the Nakiri clan, no longer languishing in solitude with her culinary obsessions.
Mana was born with the God's Tongue, a rare genetic trait from the Nakiri family that develops every few generations. Along the years the God Tongue became a curse for her as she could not taste food normally, becoming physically and mentally disgusted with tasting food to the point that even odors were repulsive enough for her. This broke her as she despaired at being unable to find food that could satisfy her, when everything else she tasted made her regurgitate. As a result of this depressive state, she left the Nakiri household and abandons Erina during her early childhood.
Senzaemon Nakiri would tell Erina that Mana went on a journey to cure herself of a sickness affecting her and that she would eventually return. Eventually, Mana became the Bookmaster and using her position she would try to find a chef that could satisfy her, albeit unsuccessfully. At this point, she would inject nutrients into her body in order to sustain herself.
