Mana Nakiri

Mana Nakiri is the Bookmaster of WGO and the wife of Senzaemon Nakiri the mother of Kirumi Nakiri and the grandmother of Erina Nakiri.

Appearance
Her first appearance in the manga saw Mana in a long, possibly traditional Japanese dress, wearing a dark-colored cardigan and donning a traditional fan.

Personality
Mana Nakiri has been shown to have an obsession towards "Superhuman Abilities," specifically those that Les Cuisiniers Noirs possess (i.e. Asahi's Cross Knives), despite vehemently denying Erina's God Tongue, referring to that as an unneeded super human ability. She has a cold demeanor, refusing 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.

Mana, however, 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 leave the Nakiri Family.

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.

History
Mana early life is unknown but she married to Senzaemon and had Two Children with him according to Kirumi stated that her mother use to have the God Tongue but lost it some year later before Erina was born and mention that she was only look after Erina when Kirumi herself was very busy with her own responsibility and stated that she trained Erina Nakiri God Tongue during Erina's childhood but she gave up all hope and left Nakiri Family and not being there even before Azami's God Tongue training begins.

Plot
Nakiri Mana makes her first appearance in Chapter 300: Prayer Book, in which she was revealed to be the Bookmaster by Nakiri Erina, as well as the person responsible for Erina's disadvantageous gauntlet-like bracket in BLUE.
