This idea popped up in my head when i was listening to a few Vocaloid songs. So... BTW the Vocaloids are human with great singing voices in this story.
THIS IS THE DISCLAIMER: I DO NOT OWN VOCALOID OR OURAN HIGH SCHOOL HOST CLUB
Chapter 1: The Host Club and the Strange Trio
Introduction: The Host Club was created by 6 beautiful male high school students and 1 female cross-dresser (sorry Haruhi) with lots of free time on their hands. They spend their free time serving female students. It is a luxuriant recreation for super rich school.
Haruhi Fujioka was running up the halls towards the abandoned music room. She was wearing a boy's uniform, which seemingly matched her short brown hair and her big brown eyes. She looked like a feminine guy.
I'm late! Haurhi thought as she burst through the doors of the Host Club.
"Welcome!" said six male students.
"Haurhi! your late as always!" a pair of twins said, synchronizing their voices together. But Hikaru Hitachiin's voice sounded more high-pitched than his twin, Karou's, voice.
"I know, I know." Haurhi exhaled. It was a bright and perfect day for a nice club to open~
"Your eyes," Tamaki Suoh flirted, "Are shining." The girl blushed completely red.
All the hosts acted perfect to make all the guests blush. Hunny (Mitsukuni Haninozuka) was eating cake lovingly with his bunny, Usa-chan, and Mori (Takashi Morinozuka) just sat there next to him, both surrounded by girls. The Hitachiin twins were using their brotherly love charms. Haruhi chatted with a few girls. Kyouya Ootori was selling photo albums of the host club. Everything was normal.
"Do I have to wear a dress?" A faint whine was heard. The hosts paused to listen.
"Do you think I want to wear one too?" another soft voice replied the first.
"So WHAT? You wear skirts."
"I wear short leggings under them."
"Oh"
The Host club quieted down. A male voice joined the other two voices, "Ha ha, you both look so cute!"
"SHUT UP!" Then the sound of someone hitting the floor is heard. Most of the guests and all of the hosts of the host club ran towards the entrance, only to find two girls(?) and one boy on the floor with a scarf. The two girls(?) looked behind them, they had shoulder length blonde hair and beautiful blue eyes they looked like twins. Then one of the girls(?) ran off. The other screamed, "HEY!" and ran after the other girl(?). The boy on the floor stood up and ran after them.
"Fine! You don't have to wear a dress!" He screamed after them.
"That was strange..." Tamaki finally spoke. "But at least my Haruhi is safe!"
So~ are you suspecting who they are? They will officially meet next chapter!~
Sorry if it's short. I'll make the next chapter longer. Oh and ignore the bold lettering in the story until I tell you to notice it.
