I'm Here to Help

"Crystal Tokyo."

"Crystalline structures, delicate spires of magic reaching to the heavens like angel's wings."

"People laughed, people smiled, people almost never cried. Why would they? They lived in Utopia."

"I hate it. I hate them. I hate her."

"Serenity. 'Neo-Queen' Serenity."

I'm Here to Help is a Sailor Moon fanfic mostly written in 1998 (but finished in 2007) by Mark Doherty. What seems to be a typical "Big Bad wants to change history" plot upon first reading quickly becomes much, MUCH more. Notable for being one of the first and best written Crystal Tokyo As Dystopia stories, which many have since tried to match.

""I killed it. A creature, youma, demon, call it what you will. Did it have dreams, aspirations, hopes? Did it wish for its life, to be hunted and killed? Did it want to be left alone?""

 * Deconstruction Fic
 * Dramatic Irony: The protagonist is unaware that Sailor Moon is Queen Serenity.

 * Identity Amnesia: Emerald cannot remember his own name or much of his past.
 * , remembers everything about his past, leading to a moment of sheer, screaming horror as these memories overwhelm him.

 * One Hit Kill: Emerald does this to one of Kunzite's youma, with Kunzite himself standing there.
