Mayumi Morita

World famous surgeon Black Jack meets a family with a strange predicament...their grandma is constantly demanding money. They struggle to deal with this beligerent elderly woman whose motives are shrouded in mystery. But when her medical problems come into play, Black Jack and his adoptive daughter-slash-assistant Pinoko are ready to operate!

In heaven, boys and girls were assigned their gender by being given a blue heart for boys and a red heart for girls. One of the cherubs does not want to stop being a cherub, so he gives one of the girls (Zafiro) his blue heart, because of Cachito's mischief, who is sent to earth as punishment to correct his mistake. The story really begins when, after a few years, the elf-like angel finds the girl and tries to convince her to return the extra blue heart he gave her. At birth, her situation is already complicated: in her kingdom, the Salic law prevails, so the king passes his baby girl off as a boy to prevent unscrupulous nobles from seizing power.

This is the story of the extraordinary Benkei, who after having met his enemy Yoshitsune in his childhood (then named 'Ushiwaka') came to guard him as a lifetime partner in later years.
