Chapter one and two follow Yaasu, a character with psychic abilities who has recently been possessed by a spirit. This spirit is hoping to confess to Ritsu, a childhood friend of Yaasu's companion named Yuuma, before moving on from the mortal realm. The spirit requests spending the evening with Ritsu but the question remains: will Yuuma comply? Even if Yuuma does climb into bed with Ritsu, will the latter reciprocate? Furthermore, why does the spirit have legs now?
Chapter three and four focus on a uke who must decide how to handle his grandfather's latest invention. The seventy-nine-year-old man is a mad scientist, and his latest product turns the uke into a twenty-nine-year-old. The justification for this invention is to gain the uke's lover's attention. Will the grandpa's insistence on groping and capturing the couple finally lead to their mutual desire for one another? Or is the grandfather just seeking a new plaything?
