Answer
Aya Ueto portrayed a high school student named Yuka Morishima in the popular Japanese drama series "3-nen B-gumi Kinpachi-sensei." Yuka's character grappled with gender dysphoria, a condition where an individual's gender identity does not align with the sex they were assigned at birth. Ueto's portrayal brought depth and nuance to the exploration of gender identity and the challenges faced by transgender individuals.
