The Tale of Mary Sue (like, OMG!)
There lived a Fangirl.
Let's call her Mary Sue.
Mary Sue was kind to all, but had a dark side, indeed, she was in horrible pain, and nobody knew of her suffering, except all the people she tearfully told.
Yes, Mary Sue was
(emo/preppy).
Everyone
(hated/loved)
her for her
(bad attitude/lovely disposition).
Mary Sue lived
(In a basement locked there by her evil foster parents, because her parents had died in a terrible accident when she was a small child, and the pain shows in her absolute inability to care for other people/in a lovely home with foster parents that loved her but couldn't see the hurt inside from her parent's death in a tragic accident that left her determined to smile not matter because that's what her parents would want).
And Mary Sue loved.
A kitsune.
No, really. That is the only option available.
One day when Mary Sue was watching television
(avoiding talking to her evil foster parents about the fight she had gotten into at school, the jerk had deserved it/quietly hiding from everyone so she doesn't have to keep up her act of not still being sniffle hurt about her parents death)
Mary Sue reaches forward, touching the screen and says
"If only I could meet you surely you'd see me for who I really am and you would soften my heart and finally help me get over the misplaced guilt I have about my parents' deaths!"
And suddenly the pendant on Mary Sue's chest glows, and she looks down and gasps
("That guy at Hot Topic sold me a radioactive necklace!"/ "Mother's necklace? But why?")
And Mary Sue is sucked into the television.
She, of course, falls onto the character of her dreams
"It's you!" She gasps.
"Hello. Do I know you?"
"I'm like your biggest fan EVER. Can I meet Youko?"
"Oh, no, it seems you know my secret. Allow me to burst into tears and be joyous that someone sees me for who I really am!"
Mary Sue is then wrenched up by the back of her shirt.
"It's another one."
"What should we do with it?"
"This one seems quite potent. It appears she has brought a wet-cardboard version of me in with her."
"Did you see what one of them did to shorty the other day? I'll give you a hint, it started with power and ended with drill."
"I didn't think it was possible for your stupidity to grow so exponentially."
"Throw her in with the flamers, dimwit."
And so Mary Sue met her untimely demise, unable to realize her full potential as a half-god, half-demon, half angel and half-demon, half-unicorn, half-dragon, all sparkley poo. She was burnt to a crisp by the Flamers, who attacked with spears of grammar correction, correct facts, and the knowledge that Kurama is not some pretty sap with a rosebush, but in fact a demon who couldn't care less about her trials, human conscious notwithstanding.
The moral?
Mary Sues are an insult to the characters.
Don't write them.
Every time someone writes Kurama paired with one, Kurama punches a baby.
Think of the babies.
Don't write Mary Sues.
