Yuiko Kurugaya is Riki's classmate whose exceptional intellect and formidable combat prowess have earned her the revered title of 'big sister' among her peers. Despite her outwardly composed and mature demeanor—often seen carrying a replica sword—she harbors an unexpected soft spot for all things adorable and delights in playfully teasing Riki. What makes her arc particularly compelling is her initial absence of ordinary human emotion; through her bonds with the Little Busters! crew, she gradually awakens to the full spectrum of feelings that connect people together.
