ふだつきのキョーコちゃん

Kenji Fudatsuki has a reputation at school as a sister-obsessed delinquent, forever hovering over Kyouko, straightening her oversized ribbon and scaring off anyone who comes near her. The truth is stranger: Kyouko is a jiangshi who needs his blood every day, and the ribbon is what holds her back. With it on she is sharp and irritable; if it slips, she turns sweet and apologetic while instinctively lunging at whoever is closest. Short comic chapters follow the pair's daily balancing act, and Kenji's real crush on his classmate Hibino.
