Kichiku Megane

Katsuya Saeki is a 25-year-old unsuccessful salaryman working in a marketing subsidiary of a pharmaceutical company whose division is at risk of being laid off. Weak-willed and shy, one evening, he comes across Mr. R, who gives him a pair of glasses that he claims to change his life. When Katsuya wears the glasses, he becomes confident and domineering, but the more he wears them, the more brutal and sadistic he becomes. The endings that the player achieves depends on which character is selected as Katsuya's love interest, whether Katsuya keeps wearing the glasses, and other choices made throughout the game.[2]
