A great bishoujo game from G-Collections and Trabulance, this is Target: Pheromone (previously released as Tottemo Pheromone)!
You are Takuya, an everyday college student who has come to Tokyo from your home city to attend university. You were kind of nervous about living in Tokyo, but your mother asked your cousin Takashi to let you live with him. You like living with your cousin and his beautiful wife, whose name is Silk, but she strikes you as a little odd sometimes. You didn't learn until later that she was really a 500-year-old witch with incredible powers of magic!

One evening while we were relaxing after dinner, an incredibly bright light suddenly filled the room, and a beautiful girl appeared right before your eyes! As she drifted slowly down towards you, you noticed she seemed to be sleeping. Without thinking, you hold out my arms to catch her... and from that moment your life has never been the same.
