The perverted serial killer who shook the world, "Shinagawa Piero," has been arrested. The killer turns out to be a 20-year-old woman! A boy, seeking to find his murdered father's missing head, writes a letter to her in prison under the name of Arata, a child welfare center worker who was counseling him. To fulfill the boy's request, Arata meets her, but when she realizes Arata did not write the letter, he abruptly proposes marriage to her to capture her interest.
The film, much like the original cartoon that gained popularity for its bold subject of marrying a murderer, starts off intriguingly. The story captivates viewers as it delves into the hidden secrets of her murders and identity, and as the relationship between the two evolves while uncovering the truth. Directed by TSUTSUMI Yukihiko with a compelling performance by YAGIRA Yuya, this bizarre marriage can be witnessed for the world premiere at BIFAN 2024.
