Takeshi Naito, a desperate man seeking to lose his virginity before ending his life, summons a succubus through a dark ritual. Instead of a fearsome demon, he meets Miyu — a tiny, inexperienced succubus girl with a loli appearance and surprisingly skillful techniques. Her small body, mischievous smile, and relentless hip movements drain him repeatedly, pushing him toward ecstasy and death. Yet something deeper begins to stir between the novice succubus and her target.

In parallel, office worker Shuu discovers a mysterious blonde doll in his room that gradually transforms into a living girl named Nina. This innocent-looking doll girl develops an obsessive attachment to him, indulging in playful yet intensely lewd acts. Her curiosity and lust know no bounds, even when Shuu’s girlfriend Hiroko gets involved, leading to daring displays of dominance right beside the sleeping lover.

Tiny Evil masterfully mixes lolita-style domination, succubus fantasy, and doll horror with heavy eroticism. The petite girls use their childish charm to overwhelm adult men, extracting pleasure while subtle emotional bonds form. Short, intense episodes focus heavily on explicit scenes, teasing dialogue, and a unique mix of sadistic playfulness and budding affection. Perfect for fans of dominant loli characters and supernatural hentai.
