Chika

The novel's main "heroine".
Unusually for the setting, born into a household with both parents present.
In order to make society once again have social intercourse, she runs a community intended to help people build their communication skills.
Perhaps as such an aim would suggest, she has an affable and light personality.
Full of passion, she always refers to herself as "ore", and is always performing all sorts of strange actions such as staging plays on the streets to help attain the interest of others. Those who she thinks are promising, she adds to her group.
Perhaps on account of her charisma and androgynous character, she is very well-liked.
