Miku Okamoto

Seven years after the events of “Chaser Game W2: The Beautiful Celestial Maidens”—Itsuki and Fuyu now live in Ito City, Shizuoka Prefecture, with their daughter Tsuki, who is in middle school. Amid their busy daily lives filled with housework, parenting, and work, the time they spend together has gradually become something they take for granted. Over the course of those seven years, their relationship has shifted from “lovers” to “family,” and subtle emotional distance has begun to emerge between them. Though their hearts are shaken by each other’s casual words and actions, they continue to maintain the appearance of a peaceful household. However, their daughter Tsuki senses the growing unease between her parents. One day, after getting caught up in trouble, Tsuki is helped by a taxi driver named Kozue. This encounter becomes a turning point, prompting Itsuki and Fuyu to finally confront their true feelings and reexamine the form their love has taken as it drifted apart.
