Natsuko Igarashi

Natsuko Igarashi (五十嵐夏子) is a main character of Electric! Pretty Cure. She is the human alter ego to Cure Spark (キュアスパーク Kyua Spaaku), the Cure of determination. Her transformation device is a laptop, which is currently rendered useless by the Outage, but when she transforms she is able to use it like before the Outage existed. Her theme color is magenta and her power revolves around fire.

Appearance
Natsuko is a slightly shorter-than-average 15 year old (prior to episode 15, she is 14) brunette with brown eyes and an average build. She wears her long hair down with small clips on her fringe near her eyes. Her casual outfit consists of a pale rose jersey, white long-sleeve top, white track pants, pink sneakers and magenta messenger bag.

Her school outfit, seen in episodes 17 - 27, is a pleated black skirt with a white business shirt, grey stockings and black leather shoes.

As a Cure, her hair becomes a pink ponytail that grows to her waist, with a small braid running down the middle. She gains a white headband with a golden starburst symbol on her head. Her outfit consists of a white vest and a magenta dress with golden hemming and boots. Both the boots and the dress go to her knees. Her transformation device becomes a bracelet made of magenta rectangular stones that she can reconvert into its previous form for use while she is transformed.

Prior to episode 21, her parents would not let her get her ears pierced. However, after episode 21, she wears golden stud earrings in her civilian form and rose quartz/gold starburst earrings in her Cure form.

Personality
She is a lively girl who is a bit gullible, but perfectly willing to stand up for what she believes in. She does everything she can to the best of her ability, but if she is aware she cannot do what is being asked of her in the first place, she will get angry at the one who gave her the task (which, most times, does not help matters). She insists she is an anime and Cure Light fan and not an otaku, but when she gets started, one can only describe her passion as "obsessive". If she feels disheartened, her normally formal style of speech becomes casual, which can land her in trouble.

Relationships

 * Hikari Kaminari - She treats Cure Light as an equal and a best friend once the two become a duo because Natsuko knows that Kaminari doesn't like being treated as a celebrity.

Etymology
Igarashi is a surname that translates to "fifty storms", tying in with the theme of electricity. It is known that lightning storms can start bushfires, while both electricity and fire can create sparks.

Natsuko means "summer child", with the "-ko" being a common name ending for girls. Summer is associated with the element of fire.
