The Classroom Across the Universe

Angela attends night school, supported by her husband and daughter; she visits her teacher, Fujitake, in the physics prep room and is surprised to find her classmate, Taketo, conducting a science experiment.

An enigmatic science teacher is assigned to teach a group of challenging students with different ages and backgrounds.

With Taketo, Angela, Kasumi, and Nagamine, the science club is officially established; Fujitake suggests they attend an academic conference to present their research; Mai, who works in a hostess club, sees that Taketo is unusually down.
