This paper toy is Super Sailor Pluto, one of the four Outer Senshi of the Solar System, as well as the guardian of the Space-Time Door, and was the sixth Sailor Senshi to be introduced in the Sailor Moon manga, this paper craft was created by Bruno Vilardi.
Her civilian identity is Setsuna Meiou. Her attacks are based around time, the underworld, space, darkness, death, precognition, and powers granted by her Garnet Orb. Sailor Pluto is stated to be the daughter of the Greek god Chronos who Chibiusa calls upon to travel through time.
She is a ruthless Senshi who strictly follows the laws, eliminating any intruders who dare came in search for the Gates of Time, stating that "all who break the taboo must be eliminated". Luna states to the others that no one is to even know that Sailor Pluto exists, and that to her knowledge no one has ever seen her. Luna calls her a "lonely warrior," noting the sadness in her eyes.
It is questionable whether she is actually human as she has been described as a goddess that guards Space and Time for eternity. [Source: wikia]
