Fair warning to those who might want to play this. It has animated CGs, and the art is of good quality, but the story is insanely depressing.
It starts with a scene of Rusette (protagonist's mother) being beat up by four bandits. She is saved by a police officer and taken to a hospital, where the doctor tells her that because of the earlier abuse, she won't be able to have children. Cut to a later scene of her walking through the rain, sobbing about how she will never be a mother, when she finds an abandoned child in a basket, Shiruka, the protagonist. Fast-forward about 11-12 years, and Rusette and Shiruka are living together happily, wearing matching outfits.
The player is now given control, and the first thing to do is a trip to the beach with the train. Matching swimsuits are bought at the beach, and after changing into the swimsuits, they run into the same four bandits that abused Rusette in the opening scene. They don't recognize her, but Rusette starts yelling at them, telling them just how the abuse affected here. Realizing who she is, the bandits intend on doing it all over again, this time including Shiruka. Luckily, they are saved by Takashi, a boy of around Shiruka's age. They introduce themselves and realize Takashi lives in the same village, and Shiruka suggests they should play. Then they all head on home.
The next day, Shiruka goes over to Takashi's house and invites her over to her house, where they do typical kid stuff. Shiruka develops a crush for Takashi during this, and tells Rusette about this, including wanting to have babies with Takashi (I wish I was making this up, but that she said). Cut to a scene of Rusette sobbing at night, realizing that Shiruka will one day have children, while she will not, and that Shiruka isn't even really her daughter. Obviously going through some fucked up change.
Because this is when it gets dark. Real fucking dark.
Shiruka wakes up the next morning alone. She notices Rusette isn't home and goes outside on her own. She finds her mother standing in front of the inn with a man, the guy with the cock-nose and ballsack-chin in the red cap. She explains to Shiruka that she arranged for her to have sex with this man as practice so that she knows when what's doing when the time comes with Takashi. She doesn't want to do this, but Rusette commands her to listen to her mother and go through with it. Shiruka follows Cock-nose inside, typical virgin first-time sex occurs, and it ends with Shiruka sobbing about how it hurt.
The next day, Shiruka wakes up and goes downstairs to find her mother sitting at the table, wearing a new fancy outfit. She asks why she is wearing those clothes, to which Rusette replies that she bought it from the money she got from Cocknose.
That's right, folks. Rusette whored out her daughter to Cocknose. But it gets worse.
Rusette then comments on how Shiruka has no activities or responsibilities during the summer vacation, and tells her that she should earn some money. She then sends her outside, naked, saying Shiruka should prostitute herself. Obviously Shiruka is pretty much crying by now.
Then there's a bit of roaming involved, and I played until I got to the brothel, where the dialogue clearly states that Shiruka is just a young girl, no older than 13, and I stopped playing there.
I usually don't mind mindbreak and enslavement and all, but a 12 year old girl being whored out by her own foster mother? Too fucking dark for my blood.
