An Hanakoizumi

An Hanakoizumi stands out as one of the most unforgettable characters in Amanomifune Academy's so-called Happiness Class — not for her academic achievements, but for her extraordinary streak of bad luck that seems to follow her everywhere, with water-related mishaps being a particular specialty. Despite the relentless misfortunes life throws her way, An never lets negativity take root; her cheerful disposition remains unshaken no matter the circumstances. Ironically, though she adores animals with all her heart, they consistently respond to her with hostility or outright avoidance. Fueled by reckless enthusiasm and genuine warmth, she charges headfirst into campus life alongside her friends, turning every stumble into a reason to smile.
