HP: You Stand in the Way of My Crown

Alan Wilson, the star performer of the Universal Circus and a rising star in the world of magic, always thought he'd become like the ringmaster: make a fortune and become the man every noble young lady adored.

After entering the magical world, Alan understood: It was time to show off his charm! Show time!

So Tom Riddle, who had been secretly forming alliances and recruiting underlings, discovered that a glittering obstacle had suddenly appeared on his path to becoming king.

Tom: Hmph, how foolish. Sweet, cloying old bee, do you think he can stop me?

Everyone at Hogwarts: Ahhh, Alan is such a handsome, adorable little angel! I want to squish him!!

Tom: ... (charging up his dark transformation) Fine. Just you wait.

Theme: The hero failed to defeat the Demon King and ended up giving himself away instead.
