Aiko Niwa (丹羽 亜衣子 Niwa Aiko?) is a student from Paulownia Academy High School, a character first introduced in the Corpse Party: Book of Shadows light novel, and a survivor of Heavenly Host Elementary School. She makes her first game appearance in Corpse Party -THE ANTHOLOGY- Sachiko's Game of Love ♥ Hysteric Birthday 2U.

Design

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.

In Corpse Party Cemetery0 and Book of Shadows light novel, Aiko is seen wearing a normal Paulownia girl's uniform.

Personality

Aiko is an intelligence agent with an interest in spiritual items and money. As a successful young woman, Aiko gives off a façade of cheerfulness, but underneath she is greedy and not someone to trust with anything. She is willing to align with good or evil depending entirely on which side benefits her more. 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 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, unethical ways. Despite this, 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.

Aiko then explains that no one is allowed to separate from the group or they will be bashed just like Shougo is, as the key to winning this game is teamwork.

Aiko then tells them that he is incorrect and that Heavenly Host still exists. Aiko then shows them a "thoughtograph" of a hallway in Heavenly Host, featuring what seems to be Yuki Kanno holding a hatchet and a book. The survivors question on how Aiko was able to produce a photo, so Aiko shows them the Everafter stones, which were inside the red box that Ayumi found in the Makina's residence.
