Harukanaru Ring

(from wikipedia.ja):

Yu Takamine was fascinated by the female pro-wrestlers she saw as a child, and overcoming her parents' opposition, she auditioned for and passed the Tokyo Women's Pro Wrestling Association Match to become a pro-wrestler.

However, this was only the first step to becoming a wrestler.

This is the story of Yu, an amateur wrestler who is not particularly strong, and her growth as an apprentice, rookie, heel, idol, and senior wrestler as she explores various fighting styles.
