Dieselmine is a Japanese dōjin soft circle that primarily develops adult visual novels and role-playing games. Active since the early 2000s, the group is known for its prolific output, often focusing on dark fantasy, corruption, and transformation themes. Many of their titles feature turn-based combat or simple adventure-game mechanics wrapped around narrative-driven scenarios. Dieselmine games are typically distributed through platforms like DLsite and have gained a niche following among players who enjoy storylines involving moral decline or supernatural coercion. While their content is explicitly for adults, the circle is recognized for consistent art styles and recurring character archetypes.
