Saeko Sakima

Saeko Sakima is a student of Saotome Gakuen, initially sorted into S Class, but was later downgraded into A Class in the anime. She is also a member of the idol group µ's.

Personality
Saeko is very energetic, sociable and has a very strong sense of perseverance. Her positive, can-do attitude gradually begins to affect everyone around her as well as the anime progresses. Her energetic and perseverant nature also makes her rather impatient and easy to tease about giving up, only to make her even more perseverant on achieving her goal. Whenever she is unlucky or having a bad day, she remains confident.

Due to her usual positive nature, however, she tends to hide her more sensitive side, and tries hard to not cry when she is frustrated, as she feels it would drag down others' morale if they were to see her cry.

Her personality is similar to Rin's because they are both determined and hard-working.

History
Her parents are divorced, her father and her mother left her because of Saeko's ambition to become an idol. She struggled to become an idol. After a short period of time, her agent began to push her to do other things instead of singing, which bruised her pride and took her away from her passion. She lived a double life as Hikari, her "twin sister", in an attempt to "have a normal life", with her childhood friend, Tokiya Ichinose, or Hayato. She was not very close with her family, she did not spend many holidays with them due to the busy work they had to do and she grew up lonesome especially on Christmas Day.

Hobbies
Saeko enjoys swimming and collecting stickers. Her special skill is often finding money on the streets, which she attributes to good luck. She likes reading as well.

Saeko becomes the group's main lyricist, and writes the song "START:DASH!!", along with most of the rest of their songs. She either created the dance steps for START:DASH!! or aided Rin in coming up with the choreography.
