Fudatsuki no Kyōko-chan (ふだつきのキョーコちゃん) is a Japanese manga series written and illustrated by Sōichirō Yamamoto.

Kenji Fudatsuki is a high school student who is a delinquent and seemingly has a sister complex as he is very protective of his sister Kyōko, fixing her hair ribbon, and not allowing anyone to get near her.

Furthermore, the reason why Kenji is always by Kyōko's side is due to her being a jiangshi who regularly needs to feed on his blood, with her ribbon serving as a talisman to prevent her from attacking people.

Keiji is determined to find a way to look out for Kyōko while overcoming his reputation so he can confess his feelings to Hibino.
