What is SPECIMEN OF YAN?

SPECIMEN OF YAN is an 18+ in-development visual novel demo by FATHER (yaniswatching), the creator of SURVIVE MIN. It moves the yandere horror formula into a different AU centered on Dr. Yan, the handsome mad doctor from the official game description.

Mature Yandere Horror

A creepy psychological horror and dating-sim story built around yandere tension, parasites, and an unsettling mad-doctor premise.

Dr. Yan's AU

A separate alternate-universe story planned to expand both Dr. Yan and Y/N with clearer motives and backstories.

Demo Now, Bigger Story Ahead

The creator's June 17, 2026 development update explains that SPECIMEN OF YAN began as shorter extra content, but grew into a longer AU project with more story, more art, and additional scenes. The full release may be pushed further while FATHER continues writing, drawing, and coding as a solo developer.

In Development

The current public build is a demo. The full game is still actively being expanded.

More Character Depth
