Tuna Girl!!

For eighteen years, Ayuka Oyama has lived under the shadow of her older sister's dismissive words. Constantly labeled as the "failed little sister," she grew up hearing that her only saving grace was the luck of being the youngest. Despite this harsh judgment, Ayuka is deeply aware of how sheltered her life has been. She knows she has been spoiled by her mother's unwavering affection and shielded from hardship by the very sister who criticizes her. Yet, rather than accepting this comfortable but unfulfilling existence, Ayuka reaches a breaking point where she decides it is time to fundamentally change who she is. Determined to shed her pampered identity, Ayuka makes an astonishing declaration: she intends to work aboard a commercial tuna fishing boat. Fully aware that such an ambition borders on the impossible for someone with no experience, she refuses to back down. Instead of remaining in the safety of her family's protection, this formerly sheltered young woman willingly volunteers to plunge into one of the most grueling and unforgiving professions imaginable. Her journey transforms from a quiet domestic struggle into a fierce battle against the brutal realities of the open sea, driven by an unshakable resolve to prove her own worth.
