Doukyo Suru Neneki

Yuuji Fujiwara had an unlucky life. As a child, he was blamed for a vase he did not break, and he was fired from his job for a colleague’s mistake. At the convenience store where he works part-time, Takamiya-san, a younger girl, blames him for mistakes made by others. When he returns home in a depressed mood, he is greeted by a strange girl. When Yuuji is puzzled, the girl reveals her true identity. It turns out to be a mucus organism that has been living with him for the past three months. The creature, which speaks human language and can change its appearance, is in love with Yuuji. He is not at all pleased with the mucus life form’s affection. In order to attract Yuji’s attention, the mucus organism changes its appearance into Takamiya-san, the co-worker at his part-time job, and seduces him.

On his routine train journey back home, Yuuji experiences an unexpected turn when he discovers that next to him is the slime that lives in his house transformed into his coworker, Takamiya-san. After an incident, the slime girl confronts a schoolgirl, but Yuuji manages to calm the situation. Once at home, unable to contain her anger, the slime girl decides to take revenge with a perverted game. She transforms into the schoolgirl and, moreover, splits herself so that the other half takes the form of Takamiya. As Yuuji has these two women at his disposal, he can’t control his passion and fucks them.
