OVA
Description
Tooru Ichii, a first-year high school student, stands at 141 centimeters with a slender build. Her small frame often leaves her swimming in ill-fitting clothes, sleeves extending past her hands. She typically wears her school uniform beneath an oversized purple sweater and thigh-high black socks that pool loosely around her thin legs. Very dark brown hair frames her face with two long side bangs and a front strand, complementing her dark red or deep pink eyes. Tooru expresses distinct dissatisfaction with her height and slimness, yearning for a more substantial build and feeling self-conscious about needing children's clothing sizes.

Her reliable and intelligent nature pairs with a generally stoic demeanor, leading some to label her a Kuudere. She harbors intense protectiveness toward her childhood friend Run Momoki, dating back to elementary school. This manifests as fierce jealousy and aggression toward anyone perceived as encroaching on Run's attention, including threats with a baseball bat. Initial hostility colors her interactions with Yuuko Nishi, stemming from a misunderstanding where Yuuko appeared compromised with Run. Tooru frequently teases Yuuko, partly fueled by envy of Yuuko's taller, more developed figure, though their relationship eventually evolves into friendship.

Social integration beyond her core circle—Run, Yuuko, and Nagisa Tennoji—poses a struggle; Tooru shows scant interest in classmates. She finds persistent attention from classmate Yutaka Imai bothersome, though gradually tolerates interactions with Yutaka and her friend Miho Noyama. Academically diligent and responsible, Tooru maintains a positive rapport with her homeroom teacher, Kimiko Kito, often assisting her. Elderly neighbors hold her in high regard, occasionally offering small gifts.

Dependency on Run defines her; separation breeds loneliness while proximity brings contentment. Conflicts, like an argument over Run's graduation, heighten Tooru's anxiety about eventual separation. Reconciliation typically follows small gestures, such as Run anonymously providing a drink. Tooru also demonstrates care for animals, adopting an abandoned kitten named Tansan and integrating the pet into daily life, even bringing it to school.

She participates increasingly in broader group activities—beach trips, summer festivals, New Year shrine visits. Key developments include her role in reconciling disagreements, like collaborative cooking resolving tensions at a Halloween gathering, and supporting sick friends. Initial reluctance toward social rituals, such as singing at karaoke, diminishes under Run's encouragement.

Tooru enjoys sweets, which friends use to placate her, and horror movies, which she leverages to tease Yuuko. Her personal growth shows in incremental shifts: accepting Yuuko and Nagisa as integral to Run's life and managing jealousy more constructively across portrayals.
