After meeting Harmonia, she became one of the legendary warriors, Cure Butterfly, who represents the butterfly effect and the consequences of small actions.

Appearance
Sachika is a girl of average to short height. She has large, magenta eyes, thin eyebrows and buttermilk blond, fluffy hair that reaches her shoulders. Sachika dyes the tips of her hair pink, and often wears it down with a half-ponytail held by a fluffy pink hairband.

Sachika loves fashion and is a bit vain, thus she cares a lot about her appearance. She could be refered to as stylish.

Personality
Sachika is a naturally talkative and confident girl, who has a bit of a self-centered and bossy nature. Before meeting Kazumi, this side of her personality was more apparent and she used to boss everyone and think of herself as the center of the world. Due to this, Sachika didn't have friends and was told by Chie that she never would have, which somewhat lowered her confidence.

But when she befriended Kazumi, Sachika started to realize that not everything was about her and began understanding other people's feelings, becoming a much more friendly and easygoing person, although her bossy, spunky and noisy traits remained. After that, she became very popular and started to truly value her friendships.

Sachika is also musically talented, being able to play the piano, guitar and having a good singing voice. She often sings along with her friends.

Relationships
Ohara Kazumi - Since the two met, they have become inseparable best friends. Sachika is extremely thankful to her friend for being her first friend and cares deeply about her, saying she's her most precious connection. The two often sing and play instruments together. However, after they become cures and find out about the prophecy of the dark cure, their bond seems to weaken and they star having many fights, until Kazumi eventually reveals that she resents Sachika and eventually cuts their ties, making Sachika extremely saddened. From then on, the two fight in enemy teams, but Sachika still seems to love her.

Ueno Chie - At first, they didn't get along at all. Chie considered Sachika an annoying and spoiled little girl, and once even told her that she would never have friends. This turned out to be a wrong accusation, since Sachika soon befriended Kazumi and then became much more popular. But when Chie's friends left and she found herself alone, Sachika approached her and said they should leave the past behind, offering to be her friend. Though it took some time, the two eventually became good friends, especially after Chie became a cure as well.

Abilities
Sachika is a young girl who is fashionable and musically talented, being able to play the piano, guitar, and sing. After meeting with the fairy Harmonia and receiving a Harmonious Link, Sachika gained the power to transform into a legendary warrior, Cure Butterfly, who can only transform if she's with Ohara Kazumi, known as Cure Choice. Later, after Kazumi pledges alliance to the Dark Agony, Sachika needs to purify her Harmonious Link in order to be enabled to transform again, this time without having to be with Kazumi. She isn't very strong, but is quite fast.
