Sora Kasugano is one of the Love Interests from the obscure Visual Novel Yosuga no Sora. She is a non-violent, light yandere.



Sora resembles her brother, having grey eyes and silvery hair. Her pale complexion accents her long hair, which is worn in twin-tails held with dark grey ribbon. She normally dresses in monotone colors; such as white, black, and grey. She is regarded as being doll-like with a fragile body.


Sora is lazy and withdrawn, spending her time usually surfing the web or eating junk food. She refuses to ever leave the house unless it involves Haruka or by force. She seems to lack any moral grounds or caring for the social norm- such as knowing how incest is not supported by anyone where they live, or breaking into Haruka's class to try to sexually please him beneath the desk.

She is easily envious and will resort to petty tactics to get Haruka away from other girls. She can become lonely without him, and only tries to show a caring side around him.

As she tries to resist doing anything in the open regarding her feelings as a result of the above, she often experiments on herself while fantasizing about him.



Haruka - Her twin brother who she obsessively loves and attempts to be with. Haruka returns her feelings, but breaks up with her after they were caught making out. Sora attempted to drown herself but he saves her, deciding to leave their new home in order to find a place more welcoming of their incestious relationship. Their relationship is the Canon one.

Nao Yorihime - An old friend from their childhood. After she caught her "seducing" Haruka and catch her force herself onto him in the past, she stopped liking her. She is hostile and rude to her, and before even hooking up with Haruka, she claimed they were having sex to rid of her.



  • She is the only girl to get pregnant in the game.
  • She enjoys pocky.
  • She fears mosquito's to the point of trying to use hair spray to rid of them.
