A Pierrot

Brothers Izumi and Haru get linked to a rash of arson fires in which suspicious writing is left on the walls. Haru was conceived when his mother was brutally attacked and raped by a criminal, and yet he is still treated as part of the family. Various ideas are explored, such as his father’s ability to love him even though they’re not biologically related and whether or not genetics actually matter within a family. —Eiga Wiki
