Background / History

Chika grew up in a fractured household. Her mother was largely absent, while her father became an alcoholic gambler who demanded her earnings, accumulated debts, and abused her. Much of Chika's childhood care came from her grandmother, whose teachings about smiling and happiness became central to Chika's outlook. 20 21 165 386 399

After her grandmother's death, Chika struggled as an idol trainee. Her fellow trainees ostracized her, hid her shoes, and tampered with her clothes. At her lowest point, the Pendulum left by her grandmother activated, allowing her to become a Magical Girl. 19 386

Using the Magician's appearance-changing magic, Chika adopted Tachibana Aeruru as her idol identity. The name honors her grandmother's original surname, while the Iris crystal is likewise a treasured inheritance with roots in R'lyeh. Her career became successful enough to pay the household's debts, but her father continued taking her income and abusing her. 19 20 217

Chika returned to school because she wanted to study, despite her anxiety around classmates and poor academic performance. A home visit by her homeroom teacher, Haihara, exposed the abuse at home; Haihara intervened against Chika's father and took Chika away. Chika subsequently stayed with Haihara temporarily. 14 20 21 22

Lord Gemstone recognizes Chika as the descendant of her former acquaintance, Ailu, who loved Earth and mortals before dying of old age. 26 109

Appearance

In everyday life, Chika is a petite, delicate girl with chestnut-blonde hair that curls slightly at the ends and light-brown eyes. Her reserved posture and tendency to lower her head make her appear especially small and anxious. 14 406

• Often wears her Iris Pendulum around her neck. 14 16
• Appears in elaborate, polished idol costumes as Tachibana Aeruru, including a dark-red performance outfit. 378 407
• As Star Flower, she wields a flamboyant microphone wand and wears floral-themed magical attire. 16
• A rose-red, flower-shaped crystal ornament later appears on Star Flower's chest. 403

Personality

Chika is deeply timid in civilian life. She stutters, avoids eye contact, becomes overwhelmed when singled out, and has difficulty speaking to strangers despite being a public idol. She is nevertheless sincere about studying and grateful for classmates who try to include her. 14 19

She becomes attached to kindness quickly, often idealizing people who treat her gently. This is especially apparent in her feelings for Haihara, whom she sees as beautiful, dependable, and heroic after being rescued from her father. Her insecurity makes her fearful of being forgotten or replaced. 14 56 69 165 333

As Star Flower, Chika presents the confidence she cannot access normally: playful, theatrical, self-assured, and eager to make people smile. Her transformation amplifies traits already within her rather than changing whom she cares about. 16 56

Tachibana's nightmare forces Chika to confront her dependence, loneliness, and habit of enduring pain in silence. Rather than breaking, she chooses to resist and later returns to the battle with greater resolve, refusing to let Tachibana demean her grandmother or decide her future. 384 386 387 407
