After the little incident with the Subterranean Queen swearing loyalty, the two monsters and hero for fun took a little time to figure out how to make this work.
For starters, Saitama simply gave one simple order to his new servant, besides the fact to not call him Master. That order? The neither she nor her people attack humans for any reason whatsoever.
The second was that the two monsters settled into another room in the apartments. Good and bad news about this arrangement. Bad news? Sub-Queen broke the door open with her strength. Good news? Who cared when humans didn't live here to break in and such?
Which now brings us to the present.
The Subterranean Queen sighed in boredom as she laid down in the empty apartment she and Vaccine Girl had settled into, which was right below Saitama's apartment. Seeing as neither monster had anything, the room was bare of practically everything.
"Bored?" Vaccine Girl asked from where she sat against the wall.
"Unbearably." she moaned as she sat up. "Now that I serve Mas-er, Saitama, I don't have anything to do."
"Same here. Well, except for serving him." Vaccine Girl nodded. "I'm only here because I need time to get my strength back. Once I'm 100%, I'm gone."
"Oh yeah. You said you got beaten by a bunch of little k-"
CHOMP!
"YEOWCH!" Sub-Queen roared in pain as Vaccine Girl bit down on her arm, her sharp teeth digging into her flesh! "GET OFF OF ME, YOU LITTLE PURPLE BRAT!" she wailed as she flailed her arm in an attempt to dislodge the diminutive monster.
"I t'ld you n'ver to mention dat!" Vaccine Girl growled, her jaw refusing to let up as she now began to beat her tiny fists and legs against the larger woman.
"If you don't let go, I'm gonna finish what Saitama started and knock the rest of you to-"
WHAM!
"-pieces?" she finished in a calmer tone, both hers and Vaccine Girl's eyes looking around in confusion. "What was that?"
WHAM! WHAM!...WHAM!
"What was that?" Vaccine Girl asked, having finally let go of Sub-Queen. The strange sound was soon followed by an endless series of what sounded like a massive fight coming from...above?
"Is he fighting someone?" asked the larger monster. Vaccine Girl was about to open the glass door to shout up at Saitama, only to pause when she spotted a black cloud moving in the distance, followed by an announement blaring throughout the area.
"ATTENTION! THIS IS AN IMPORTANT ANNOUNCEMENT! THREAT LEVEL: DEMON! ALL CITIZENS, PLEASE REMAIN INDOORS! I REPEAT-"
"What...was...that?!" both monsters asked in shock.
-Somewhere in City-Z-
The streets were completely barren than usual due to the warning.
SMASH!
Correction: They were semi-barren due to one individual carrying a large sack behind him with one hand and a crowbar in the other.
"Haha! They're all empty because of that warning!" laughed the thief. "Like anyone's gonna die because of a mosquito bite." The punk looked down at his massive bag of loot, a grin on his face. "So what if I lose a little blood? It's worth it if I can get all this." He nearly fell over when something flew past him, blowing his beanie off his head in the process. "Was that the wind?"
He wouldn't have time to wish that it was the wind.
His eyes were glued to the sky, so he didn't even notice until he felt something crawling on his skin that something was wrong.
"What the?!" he cried out before his entire body was covered in what had to be hundreds, if not thousands, of mosquitoes. Very thirsty mosquitoes.
"AAAAHAHHAaaah...ahh..gghh." the thief coughed up before the mosquitoes flew off, leaving nothing but a shriveled corpse behind. The mosquitoes then flew into high into the air and began encircling a figure.
"Mmmm! Ooooh!" the figure moaned before the mosquitoes dispersed, revealing a voluptuous half human, half mosquito woman flying above them.
"Come on guys. That wasn't nearly enough to satisfy my needs." she whined. "Now, go get some more." she commanded before she blinked, sensing something nearby.
"Target acquired!"
Her inhuman speed and reflexes allowed her to safely maneuver around the fireball meant to destroy her. She glared down at the one that would be foolish enough to attack her.
"I see now." began the cyborg standing below her on the ground. "You have the mosquitoes suck the blood out of their victims, and then take it all for yourself. You must be controlling each one via some sort of telepathy. So if I were to get rid of you, their leader, then the swarm should disperse." he finished, his cybernetic eyes locked firmly on her hovering form. The monster merely let out a chuckle as she leered down at him with a smile.
"Our next meal is here. Go drain that fool dry." she ordered. She watched as the cyborg was eveloped in a ball of swirling darkness. Her smile dropped when said ball erupted into flames, killing off every mosquito within it's range, shocking her greatly.
"I will eliminate you." the cyborg stated, the same flame used to destroy the mosquitoes gathering in the palm he was now aiming at her. "Stay right where you are." Mosquito Girl was broken from her shock by his words and giggled at his statement.
"You think you can eliminate me?" she asked before gaining a psychotic smile. "THEN GO ON AND TRY!"
