Hinako Tsuwabuki is one of the leading members of the Zuka Club and is known as "The Lady of the Daisy." Hinako is the youngest member of the club's leading council, being in her first year of high school, and is arguably the most energetic of the three girls. However, as acknowledged by Chizuru, Hinako seems to be very intelligent. Hinako's nickname is "Hinagiku" as mentioned by Chizuru Maihara in Ep 09 - A Challenge from Lobelia Girls' Academy!
