Overhaul must have sense the spike of danger the instant she moves because Izuku watches when the villain suddenly stands up from his chair and is about to use his quirk and probably reconstruct his underground office into a death trap.
However, Izuku is faster than he is.
"I don't think so Overhaul," She says even though the villain can't hear her yet.
In a burst of speed, she zips forward and in a matter of seconds she is right beside the villain.
Without hesitation, Izuku grabs a hold of his arm and swiftly slams the villain's tall, lean figure against his L-shaped desk.
At once, the stacks of papers, desk organizers containing pens and other office supplies scatter and come tumbling down the moment Izuku pins the Yakuza-leader into the flat surface of his oaken desk.
Izuku momentarily notes the way Overhaul's amber eyes widen in obvious shock at her unexpected and rough manhandling of him.
He is clearly taken aback by how she has managed to pin both of his arms on either side of his head before he can use his quirk.
In her ethereal form, Izuku is incredibly and inhumanly strong, which allows Izuku to pin her prey while she feeds on them. However, in the last month, Izuku has only been feeding on her sleeping classmates. Kai Chisaki, on the other hand, is wide awake and who thankfully can't see her yet.
Hence, Izuku takes advantage of that and lets her instincts dictate what she needs to do.
She is there for a reason and one reason alone.
Izuku Midoriya is finally going to satiate the growing hunger deep inside her.
At the thought, a rush of venom floods her mouth while she can feel how her shadow fangs lengthen and ready to bury itself into the villain in front of her.
Soon she will be able to taste the darkness she can sense within his heart.
Izuku is hungry - starving really, that she can no longer hold the monstrous thing that hungers for the villain partly lying on the desk before her.
Overwhelmed by blinding need, Izuku climbs unto the desk, straddles Kai Chisaki's lean hips, and tears off his navy blue vest and the pristine white dress shirt beneath it with the use of one hand.
The sound of cloth tearing is nearly deafening inside the room, which is soon followed by the sharp consecutive clicks as buttons fly everywhere the instant Izuku tears the villain's upper clothes.
She briefly manages to hear Overhaul's sharp intake of breath when she shreds his probably expensive dress shirt and the dark vest in mere seconds.
However, Izuku's mind is no longer her own.
It has not been on her own the moment she falls asleep, where this dark part inside of her - the hungry part of her - awakens to feed.
The original Izuku is not aware of the dark persona that resides inside of herself.
Her.
Dark Heart.
The dark Izuku who is able to travel through the ether. The monster who hungers for darkness living within her enemies.
Meanwhile, when the original Izuku wakes up again in the morning, she will not remember all of this. The oblivious, innocent Izuku Midoriya will simply assume these night time hunts as nothing more than dreams - no, nightmares truly.
As Dark Heart gazes down at the man beneath her, she can no longer reign herself.
She needs to feed on Kai Chisaki.
Consequences be damn.
After ripping the impediment off from her prey, Dark Heart quickly wraps her hand around Overhaul's wrist and pins his arms on the desk back before the villain can stop her chance to feed on him.
Izuku briefly notes the villain's sculpted chest and the hard planes of his abdominal muscles. Then, her gaze ends on the area where she can almost hear the wild racing of his heart and senses the swirling darkness there as well.
When she can feel the lurking darkness within Overhaul, there is a sudden - and almost animalistic - growl that reverberates from the back of Izuku's throat while she tightens a hold on her prey, whose body lay frozen and tense beneath her.
"What are you - " Overhaul is about to say, but he is unable to finish his sentence the instant Izuku bares her shadow fangs and finally moves unto him with predatory intent.
Driven by pure instinct alone, Dark Izuku finally sinks her shadow fangs into the flesh of her enemy right where the darkness resides.
As soon as Izuku clamps her mouth on Overhaul's exposed skin, she hears him gasp in surprise which is soon followed by a hiss from the villain's lips after her fangs punctures through his very soul.
And when Izuku starts feeding - starts sucking on him, Overhaul's entire body involuntarily arches beneath her.
Instantly, an unbidden moan of pleasure slips past her parted lips when Izuku tastes the darkness whirling in her mouth and seeps at the tip of her tongue.
Overhaul's darkness taste sinfully divine. Like a sweet, forbidden fruit that Izuku can't help but savor and succumb to its temptation.
Finally, finally...Izuku is able to satisfy the gnawing emptiness - the raw hunger that she tries to suppress for nearly a month.
More than that, her feeding also entails that she has access to her prey's consciousness.
So the second Izuku begins to siphon the darkness inside of her prey, her mind is soon bombarded by images, information, and secrets that her enemy has kept in all the twenty-eight years he has been alive.
As Izuku continues to feed on Overhaul with no restraint, she also manages to tap on her prey's current emotional state.
Now, she can sense his emotion as deeply as he must be feeling hers at that moment.
She feels an amalgamation of fury, a hint of fear, a flicker of excitement, and the building lust that is often triggered from her potent venom and this will only increase if Izuku continues to feed on him.
Hungry for more, she tightens her hold around Overhaul's wrist to keep him pin beneath her while the villain tries to throw her off him by bucking his hips against her.
"Get off me demon! Get the hell off me -!" Overhaul demands in rage, but his yells swiftly die down in his throat when Izuku opens her mouth wide and sinks her shadow fangs even further while her tongue accidentally grazes against his nipple.
Almost at once, Overhaul stiffens beneath her, where she instantly senses the spark of liquid heat that goes through the villain due to her unwarranted action.
Overhaul's blissful response echoes through her because Izuku feels an unfamiliar sensation curling low at the pit of her belly.
She doesn't know what makes her do it, but it must be a mixture between curiosity and wanting to feel that pleasurable sensation again for herself, when Izuku does it again without thinking.
She swirls her tongue around Overhaul's hardening nipple while she continues to feed on him.
As she does so, a choke gasps tears free from Overhaul's mouth just as another flare of what Izuku begins to understand as pleasure forces the villain to arch his back.
At the villain's reaction, Izuku can't help herself from latching into that emotion like a starving beast and whirls her tongue again and feels another sensation of pleasure that sweeps through the villain from the point of contact and seems to travel towards the same area where she soon senses something hot and hard pressing against her.
At the same time, she suddenly feels a rush of moisture right between her thighs.
Izuku wants more.
She needs to feel all of him.
She wants to feel this pleasant sensation again and again that Izuku starts experimentally sucking unto him hard that the villain's breathing turn ragged and Overhaul starts to move his hips against hers.
Izuku feels heady with what she realizes is desire as she repeats the process.
She grazes and sucks unto her enemy's sensitive flesh repeatedly until all she can sense is her prey's growing need to take her right then and there. She listens to Overhaul's loud groans every time he grinds himself against her, which makes her silken heat clench with excitement while another gush of moisture gathers at her core.
Izuku can't help but moan at the explicit sensation.
However, Overhaul's rubbing against her has distracted her so much that Izuku fails to notice her loosening grip on her adversary's wrists.
It is only when Overhaul suddenly moves beneath her that Izuku's realize that she is a fool for becoming distracted by Overhaul's erotic movements.
In a blur of motion, the villain manages to spring free from her hold.
Then, the Yakuza-leader twists around and suddenly slams her back into the desk, where he proceeds to cage her there with his tall, mascular frame.
Overhaul looms over her figure while he traps her on the desk with one gloved hand on her wrists.
The villain's unexpected action has made Izuku hit her head on the oaken desk with such force that it jars her momentarily.
And when she finally looks up, Izuku freezes when she notices how Overhaul is staring at her with his mouth slightly parted. Obviously shocked to see her there.
A roar of adrenaline floods through her bloodstream when Izuku realizes that Overhaul has reversed their position in a span of a few seconds when she has become distracted.
He can apparently see her now too.
Clearly, Izuku has become corporeal after she fed on his dark energy.
"You!" the young Yakuza-leader says in an almost accusatory tone, but Izuku notes the hint of surprise and confusion in his handsome face which remains uncovered even after her arrival there.
"What are you doing here?!" Kai Chisaki demands as he tightens his hold around her wrists.
Izuku notices the way Overhaul's gaze seems to linger on her figure for far longer than necessary.
She can hardly blame the villain, especially when she happens to be completely naked beneath him.
She is always in such a state when she is in her ethereal form and ready to feed. Izuku considers it partly an Astral projection but she only becomes corporeal after feeding on her prey's dark energy while her real body lays somewhere in the U.A. dormitory.
It is also for this very reason that Overhaul has not broken down in hives when their bare skin make contact. He can't affect her or truly harm her in anyway while she is in that form. The villain must have realize the same thing because he takes this unusual occurrence in stride.
In fact, Overhaul's focus seems to sharpen on her very naked figure just within his reach.
Izuku watches as the villain's golden orbs flicker from her face before moving downwards to examine the rest of her womanly curves. From her full breasts, to her small waist, then to her wide hips and lastly to the area between her legs where Izuku uses this to her advantage.
"What do you think? I came here to have a taste of you," Izuku says to him while she shamelessly opens her thighs further to give him a better view of her.
And just like that, Kai Chisaki seems to stop breathing altogether when she tells him this while his gaze remains transfix between her open thighs where she can feel herself getting wet and aroused at the way Overhaul keeps on staring at her with such heat.
With Overhaul temporarily distracted, Izuku makes her final move.
Thus, Izuku tears her hands off from Overhaul's hold, shoves the villain off her, and then forcefully pushes the shock man onto his leather-padded office chair.
Next, Izuku climbs into his lap and roughly grabs a hold of her enemy's silken locks right before she yanks his head to the side, and sinks her shadow fangs into the skin of his neck.
Izuku is not quite done with her feeding and she is not about to stop anytime soon until she has gorged herself in Overhaul's essence.
Meanwhile, Kai Chisaki starts to move against her, but when Izuku purposely grinds herself against that hardness she can feel pressing between her thighs, the Yakuza-leader suddenly lets out a sharp inhale which is soon followed by a curse.
"Fuck!" Overhaul grits out again when Izuku does another experimental roll of her hips, which she learns can elicit that pleasurable sensation centered at her silken core.
It looks to have the desired effect on her enemy because Kai Chisaki seems to be torn between pushing her off him or pulling her hips down on him to create that exquisite friction between their bodies.
In the end, the villain finally chooses to do the latter.
