Asia, surrounded by Rias' busty friends, feels a pang of jealousy as she compares their developed bosoms to her own. In a fit of envy, she retreats to her room, stripping off her clothes to examine her naked body in the mirror. She cups her breasts, wishing they were bigger, and begins to touch herself, her fingers finding her wet slit. Her imagination runs wild with fantasies of her breasts growing and attracting the attention of her friends and classmates. Lost in her self-pleasure, she doesn't hear Rias enter, catching her in the act. Asia, embarrassed, confesses her jealousy, and Rias reassures her, promising that her breasts will grow with time.
