Enfer bleu

Following the death of her parents, Mana is adopted by friends of her family who already have three children: Kakeru, older than Mana, and the twins, Riku and Yu. One might think that in her misfortune, little Mana is lucky to find a loving home. Yet Mana suffers. She lives in fear of being physically and psychologically abused by the eldest of the siblings. Indeed, Kakeru the kind boy, Kakeru the attentive, the handsome Kakeru... is a merciless torturer and tyrant, from whom she wants to escape. But how to do it? Who can believe her? If she spoke up, she would become guilty of discrediting those who generously welcomed her. She seems forever trapped in this unhealthy love, until Akihiro, a boy in love with her, discovers her terrible secret.
