Akemi is Yui's younger adoptive sister, like Yui. Akemi was sent along with her older sister to her distant relatives since Akemi might struggle to live on her own. While in there, she began to hear noises, witness Yui being bitten or even some odd things happening around, therefore it was backfired to hers as well. Sometimes being the little sister was actually the hardest and scariest. Especially if you have a stupid, submissive older sibling around you, it wasn't the usual situation she experiences back then. It was even more thrilling when someone has his eyes on her and will be determined to be his. [originally from quotev. i am also the author here]
