  • Koan’s name is derived from the Japanese word for kermesite - “kouankou” (紅安鉱).
  • She was the youngest of the Ayakashi Sisters.
  • Much like her rival Sailor Mars, Koan’s element was fire.
  • In the manga, Sailor Moon killed Koan. Yet in the first anime adaptation, Koan survived and she was eventually purged of evil.

A lot of girls will never understand how hard it is for girls like me to look at ourselves in the mirror. How sad it is to not be the first to ask to dance. To have a guy come up to you and not ask you for your number. To not be wanted. To not be lust after. To be terrified of taking a picture where someone shows your body bc you look a million times bigger than your friends. Or even something as simple as having to hide pieces of you people will find repulsing like..my stretch marks. Everyone says people will love you for who you are…but after 28 years the reality is people dont.
