Nakiri Erina♀

The main female protagonist and primary antagonistic rival to Soma, until becoming more than a friendly rivalry. Due to her background as one of the prestigious families of high class Japanese food chain industry, the Totsuki Corporation, Erina often looks down upon whoever is considered "common" and unjust to her taste due to her family regal pedigree. Having a fearsome reputation for her God's Tongue to taste any food and accurately describe the taste, Erina is able to disqualify anyone whose dish tastes "bad" and her foul critique could break chef and student alike. However, she also gives credit to chefs with skill (other than Souma). She is also part of Elite Ten Council as the 10th seath.
