Hibiki #12 is a very calm Sekirei of Seo Kaoru. She was adjusted by Asama Takehito. She is the twin sister of Hikari. Both have the power of electricity. In the first and second stages Hibiki seeks to fight unwinged Sekirei together with Hikari. It is later stated by Homura that although she and her sister are the underdogs they have more expertise in fighting than himself.
She is aware that Seo is not the most impressive of Ashikabi (which gives her and Hikari the reputation of being the Sekirei of the "Loser Ashikabi"), but they both like and are willing to defend him. They refuse to let Seo wing any other Sekirei by striking Seo with lighting. Her name means "sound" literally or "thunder" allegorically.
Hibiki is tall with a slender build. She has long black hair that she wears in two ponytails and hazel eyes. Despite being Hikari's twin sister and looks exactly like her, the only physical difference between the two is that Hibiki's bust is significantly smaller.
In the anime Hibiki is wearing purple or pink suits (brighter ones in the manga). Minato called the sisters in the beginning of the series often as the "Onee chans with S&M clothes".
Hibiki is the absolute opposite of her twin-sister Hikari. She is calm and composed and often enough suffers from the short-tempered attitude of her twin sister.
Abilities and Powers
She has the power of electricity. Her Norito is a rather unique one, cause she seems only be able to use it together with Hikari. The prayer "We're the pledged thunderclap. No disaster will hit our Ashikabi" causes a huge lightning strike.
