Like a lot of teenagers and 20-somethings, "Eric Draven" used to keep a Tumblr. The microblogging platform has a strong community aspect, and it's easy to find people who like the same things — or are undergoing the same struggles — as you. There aren't many people undergoing the exact same struggles as Draven (a pseudonym taken from goth classic The Crow), though: unlike most teenagers and 20-somethings, Draven isn't, he claims, human. He might present as human, yes, but really he's a "fictive and otherkin who, in previous lives, has been a Deku Scrub and a dark elf." He's also "transethnic (Japanese) and andrognous [sic]."
What does this mean? An otherkin is a being born into the wrong body. Not just with the wrong parts, but as the wrong species: people who identify as otherkin believe that they are a wolves, or elves, or really any kind of being, born into a human body. (Furries, who focus on anthropomorphic animals and are known for dressing up, aren't the same thing as otherkin, many of whom don't dress up or change their appearances at all.) A fictive is like an otherkin where the true, internal identity is a fictional character — deku scrubs are tiny creatures from The Legend of Zelda series of video games. Transethnicity is this same phenomenon applied to ethnicity.
Draven, in other words, is a Japanese wood creature from The Legend of Zelda who was born into the body of a regular white kid.
