The Shojo is a spiritual-like monster one of the few hence why it could be trapped inside a Sake bottle. Majority of all monster aka Eve's children are mutated humaniod creatures with enhanced strength, some shapeshifting, and enhance senses. Very few monters have real supernatural powers that isn't related to their shapeshifting like gaining craws or fangs. Like how their are spiritual hellish creatures that aren't demons the Daeva and hellhounds.: The Twilight of Your Despair 21:38, April 6, 2012 (UTC)
From the Transcript of what was on the page Sam how on his computer.
A Shojo (Heavy drinker or Orangutan) is a kind of Japanese sea spirit with a red face and hair and a fondness for alcohol. Legend has it, that workers at the breweries in Japan have seen a Shojo lurking about after indulging in their products. With the right Spell Box you can harness a Shojo to your will. The legend is the subject of a Noh play of the same name. There is a Noh mask for this character, as well as a type of Kabuki stage makeup, that bares [sic] the name. The Chinese and Japanese characters for Orangutan are the same, and can also be used in Japanese to refer to someone who is particularly fond of alcohol.

First off, it's noticeably NOT a child of Eve, didn't fit the profile. It's like a Wraith; invisible, but able to exert physical force. All in all, you're all right. -- ImperiexSeed, 8:08 PM, April 6th 2012
According to Salute to Supernatural season 6 all supernatural beings besides Angels the collective terms, deities, demons, hellish creatures the whore, hellhounds etc, fairies, levianthans are linked in someway to Eve.: The Twilight of Your Despair 00:17, April 7, 2012 (UTC)
You know what, the whole thing's confusing. It was called both a spirit and a monster in the episode, I don't get it myself. -- ImperiexSeed, 8:26 PM, April 6th 2012
Its a spiritual like monster. It may not eat humans, but I find hard to believe that Eve only created monsters that have only mutated powers like enhance strength or craw or fang generation. Hell the crocotta is able to devour souls of its victims that more supernatural that a vampire's teeth as they are just located higher in the gums and its a monster not a demon, deity or fairy and for sure not an angel. The same with a shtriga sucking out Spiritus Vitae with is latin for "Breath of Life." : The Twilight of Your Despair 00:34, April 7, 2012 (UTC)
