Hibiki

Hibiki (#12) is one of the two Sekirei bonded to Seo Kaoru, distinguished from her twin sister Hikari by her quieter and calmer disposition. She was adjusted by Asama Takehito. Both women have the power to manipulate lightning/electricity. In the first and second stages of the Sekirei Plan, Hibiki seeks to fight unwinged Sekirei together with Hikari. It is later stated by Homura that although she and her sister are "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 care for and are willing to defend him. They refuse to let Seo wing or even flirt with any other Sekirei by striking Seo with lightning. 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 looking exactly like her, the only physical difference between the two is that Hibiki's bust is significantly smaller. In the anime Hibiki wears a purple or pink bodysuit (a brighter one in the manga). Minato often referred to the sisters in the beginning of the series as the "Onee-chans with S&M clothes". Hibiki is the absolute opposite of her twin sister Hikari. She is calm, mature, and composed and often suffers from the short-tempered and immature attitude of her twin sister.
