Gensoukyou:Rin Satsuki

Background
Rin Satsuki was born into a family of music players,her mother's side played woodwind and string instruments while her father's side played percussion and brass instruments. She was given a erhu as her birthday present a few years back and learnt how to play it perfectly. But,instead of being a performer like her family,she studied medicine,and was a nurse for a short while at a local clinic somewhere in Japan for a couple of years. After something happened to her family,she stumbled into Gensoukyou by a complete accident,most people thought she looked like a human despite her Kirin heritage. She lives on a cliff somewhere now and wants to meet all of Gensoukyou's residents.

Personality
Rin is usually very quiet and shy,so she doesn't speak that much. But doesn't know how to use danmaku either,so she often writes down how people use their powers and transform it into danmaku to see if it might work for her.

Power
Although it isn't clear what her ability may be,some people think it has to do with Music,like the Prismriver Sisters. She might learn how to use danmaku when playing her erhu. She mostly resorts to smacking someone upside the head with it when angered.

Major

 * Iku Nagae: She knows Iku from them meeting somewhere once,and knows that she is very protective of Tenshi,like Tenshi also,she looks up to her a bit and thinks she is a good resident/friend.
 * The Prismriver Sisters: She looks up to the sisters aswell, mostly liking their music talents which make her feel that she isn't the only one who likes to play music.

Minor

 * Every other resident in Gensoukyou: Rin doesn't know that many people, so she doesn't have that many relationships.

Trivia
Rin Satsuki is often considered a fan character due to the lack of information.

She was supposed to be in Embodiment of Scarlet Devil, but was removed before the final copy was released, people can find Rin in the game's source code. Yet she does have quite a few fans, leading to people making a fanmade theme, art, their own theories who Rin is, etc.
