OVA
Description
Chizuru Akaba holds the position of secretary in Hekiyou Academy's 32nd Student Council. She exhibits a tall, model-like stature with dark brown or black hair and purple eyes, born on November 22 with blood type AB. Her demeanor projects maturity, seriousness, and a cool elegance, often appearing aloof and difficult to approach. Beneath this composed exterior lies a pronounced sadistic streak, particularly evident in manipulative behaviors such as "brainwashing" Ken Sugisaki and affectionately nicknamed "Aka-chan" Kurimu Sakurano. This sadism fully surfaced after forming a friendship with Kurimu, whom she enjoys controlling through cuddling or sisterly "abuse," frequently referencing her penchant for domination. Despite her typically collected nature, she occasionally reveals a playful side, like hopping in a sheep costume while uttering "mokyu." She struggles with mornings and shows vulnerability when confronted about her feelings for Ken.

Emotional scars from middle school shape her past, where bullying by former friend Kanade Mayashiro—stemming from Kanade's complex household—led Chizuru to reject friendships upon entering Hekiyou Academy. Kurimu's persistent overtures eventually broke through her defenses, forging a bond that simultaneously intensified Chizuru's sadistic tendencies. During her second year, a chance autumn encounter with heartbroken Ken Sugisaki facilitated mutual healing, mending her middle school trauma and unveiling latent compassion.

Throughout the series, subtle hints of unresolved romantic feelings for Ken emerge. She routinely calls him her "slave," even setting his ringtone to repeat "my slave." Their interactions evolve to include moments of nervousness and fluster, particularly during emotional vulnerability. In the Valentine's Day OVA, she battles uncharacteristic shyness while attempting to give him chocolate. By graduation in "Lv.2," her hostility toward Ken diminishes amid increased meta-commentary on otaku culture, though her core traits persist. Her story concludes without definitive romantic resolution.

Additional details include her dislike of overly sweet foods and preference for cheese. Her name carries symbolism: "Chizuru" (千鶴) merges "thousand" and "crane," alluding to a Japanese wish-granting legend, while "Akaba" (紅葉) means "crimson leaves," aligning with her autumn motif. She occasionally takes part-time roles like detective or consultant and demonstrates financial acumen through stock market insights. Lilicia Toudou deems her the sole dangerous figure in the student council due to her manipulative prowess.
