Juliet was still a little girl when her family (the Capulets) was massacred before her very eyes by the Montague family (Montagues), and Juliet was saved by the skin of her teeth.
14 years later, the Montagues, who have reigned over Neo Verona since the assault, are still searching for the last Capulet descendant.
She is, however, well hidden and dresses as a boy to remain unnoticed; her "protectors" call her Odin so as not to arouse suspicion. She spends her time protecting the widow and the orphan under the name of Red Wind/Purple Wind/Red Tornado (depending on the translation)
Despite all this, Juliet doesn't know anything, doesn't remember the massacre of her family and doesn't understand why she always has to dress as a boy, but all will be revealed to her on her 16th birthday.
Meanwhile, Romeo, son of the tyrant Neo Verona, is engaged to a girl he couldn't care less about.
