A person has died without love is reborn as a Nakuodo. Kira, the Nakuodo of Tokyo, has the duty to match people with their loves by dragging their cores together. He has no troubles until he meets Suzuki, Tsubaki, a girl whose core refuses to be matched. Going to extreme measures to match her core, Kira might even lose the thing that makes him a Nakuodo- his inablility to love.
