The second installment of "School Swimsuit: School-Approved Lewd Costume" finally arrives after more than 11 years! Bright and cheerful schoolgirl Mirai harbors romantic feelings—but not for a boy her age. Instead, she's drawn to the middle-aged janitor. Unable to connect with boys her own age, this mysterious man becomes her only emotional outlet. Then one day, an upperclassman suddenly confesses his love and forcefully starts touching her body. Confused and overwhelmed, Mirai decides to surrender herself completely—but in that moment, it's the janitor's face that appears in her mind.
