Akane starts as an unconfident, moody teenager lacking motivation, actively avoiding school due to social anxiety from a conflict within her friend group. This anxiety stems from her failure to support a friend ostracized for refusing to wear a hair clip. She also resists meaningful communication with her mother, feeling burdened by her requests.
The day before her birthday, Akane’s mother sends her to her aunt Chii’s eclectic curio shop to retrieve a gift. There, she encounters the alchemist Hippocrates and his elven apprentice Pipo emerging from the basement, revealing a portal to Wonderland. Identified as the prophesied "Goddess of the Green Wind" destined to save Wonderland from a drought threatening its water supply, Akane is whisked away alongside her adventurous aunt Chii. Her initial reluctance is symbolized by a practical ponytail shifting to loose hair as she crosses into this parallel world.
Traversing Wonderland’s diverse regions—rustic villages, industrial towns, deserts, and snowy landscapes—Akane remains passive early on, relying on guidance from Hippocrates, Pipo, and the proactive Chii. Her role as savior feels imposed rather than earned, and she depends on adult figures instead of driving the narrative. Encounters with whimsical inhabitants like oversized sheep, cat-bureaucrats, and fairy-like beings rarely demand decisive action from her.
A pivotal shift occurs during the climax against Zan Gu, a cursed prince. Rather than using force, Akane resolves the conflict through empathy, understanding his transformation stemmed from fear of failing a critical rain ceremony where past kings sacrificed their lives if unsuccessful. This emotional connection breaks his curse, restoring Wonderland’s water. Her development culminates in crafting a "Momentum Anchor" necklace for the prince, symbolizing newfound agency.
Returning to her ordinary world after three days, Akane exhibits subtle internal growth: increased self-confidence and kindness. She proactively reconciles the school conflict by gifting Wonderland souvenirs to her friends, including the ostracized girl. Visually, her renewed bond with her mother is emphasized as she sits beside her in shared sunlight, contrasting their earlier separation. She retains a lasting deference to cats, acquired during Wonderland’s courtroom encounter with feline judges.
