Kirisaki Jack no Kokuhaku.

The body of a young woman is discovered in a park in Tokyo with all her organs removed. The case is assigned to Detective Inukai, a usually cool and unemotional detective known for seeing through the lies of others. But Inukai has a young daughter in need of a kidney transplant, so when the first crime is followed by two similar crimes, Inukai is caught between his roles as a detective and a father.
