Sagara Shitara works as a school nurse. Her defining characteristic is her persistent, overt pursuit of student Takagi, who consistently rebuffs her advances. Their encounters occur frequently in the school infirmary, often initiated by Takagi's accident-prone nature leading to injuries requiring treatment.

Her attempts to seduce Takagi involve constantly plotting new, perverted methods. These efforts consistently fail, forming a recurring comedic element within the series. This sexually aggressive and shameless behavior defines her narrative role.

Her interactions contribute significantly to the series' prevalent sexual innuendo. Originating as a four-panel manga utilizing quick-paced, interwoven storylines with a regular cast, Sagara Shitara's pursuit of Takagi represents one of these core storylines.
