—Aiko Niwa, Corpse Party: Blood Drive
Aiko Niwa (丹羽 亜衣子 Niwa Aiko ) is one of main characters during Corpse Party: Blood Drive, first introduced in Corpse Party: Book of Shadows light novel. She's a student from Paulownia Academy High School and a younger sister of Kuon Niwa.
Aiko is a teenage girl of above average height and below average weight. She has long, black hair with light blue highlights. Two blue ribbons are tied in it. Aiko seems to have an interesting fashion sense, wearing a gold necklace with a pink gem, and a short purple yukata with a red skirt underneath. She wears geta with long stockings tied with light blue ribbons. She is also occasionally seen wearing Paulownia Academy High School female uniform.
Aiko is an intelligence agent with an interest in spiritual items and money. As a successful young lady, she gives off a façade of cheerfulness, but underneath she is just greedy. As described by the closest person she has to a friend, Aiko is a gossip interested in other people's private lives, using her spiritual powers her to her advantage in order to manipulate other people and find out more about them. With all of her customers, Aiko exchanges information, but they must give her money in return, or a supernatural item of equal value. She turns dark when people do not fulfill their promises to her and seeks vengeance on them in harsh ways.
Despite this, her characteristics are not as degraded as Magari Mizuki's, as she does have genuine care for the few friends that she has and mourns for their deaths and she feels sympathy for Sachiko Shinozaki.
She is the younger sister of Kuon Niwa and often shows her anger towards her sister's controlling nature.
