My Harem System In My Hero Academia

Yami sprinted toward the Zero Pointer, his ribs lashing out like blood-soaked white tentacles, clearing debris and yanking injured examinees to safety. 

Some students screamed, fainting at the sight of his gory, bone-like tentacles. Yami barely noticed their reactions; he focused on the massive robot towering above the fake city.

'Damn, that thing's huge,' he thought, the corners of his mouth twitching into a smirk.

As he ran past the fleeing students, his golden eyes recognized Ida, who had run away from the robot. 

Yami's gaze hardened. Without slowing down, he shot Ida a sharp look that screamed, "Pussy" as their eyes locked. 

Ida flinched as Yami sped past him, leaving him in a cloud of dust.

Yami weaved through the stampede of examinees, his ribs slicing through fallen streetlamps and smashed storefronts to clear his path. 

His mind raced, analyzing the Zero Pointer's weak points. "Leg joints...maybe the neck?" he mumbled. "Gotta find a way to bring that thing down without—"

A loud mechanical groan cut stopped his thoughts. The Zero Pointer's arms moved, swinging as it pulverized a nearby building. 

The impact sent shockwaves rippling through the ground, throwing several students off their feet and forming clouds of dense dust.

Yami gritted his teeth. "Of course you do."

Once he was within range, Yami propelled himself forward with a powerful thrust from his ribs. 

The force shattered the bones, but Yami didn't care. They would regenerate. 

He landed on the robot's leg with a heavy thud, his fingers digging into the cold metal for balance.

The vibrations from the machine's movements rattled his shattered bones. His ribs splintered further under the strain, but Yami quickly retracted them, petrifying the fractures to heal the damage. 'Stay focused', he told himself.

His ribs shot out again, opening like pincers and digging into the robot's leg. 

With each strike, he climbed higher, his bones acting as makeshift grappling hooks. Sparks flew as the sharp, petrified coated ribs, now obsidian-like appendages, scraped against the robot's armour.

The climb was brutal. Each movement sent waves of pain through his chest, but Yami pushed through, grinning like a maniac all the way to the top. 

He lived for moments like this—moments when the odds were stacked against him, and every second counted; they made him just as alive as sex.

As he reached the robot's upper torso, Yami stopped to catch his breath. His left arm and chest petrified, the black, obsidian-like texture glinting in the sunlight. 

With a sharp inhale, he slammed his petrified arm against his chest, sharpening it into a jagged blade.

"Let's see how tough you really are," he growled, positioning himself near the robot's neck. He raised his arm, preparing to strike—

"SSSMMMAAAASSSSHHHHH!!!"

The deafening scream made Yami turn back into the air. Yami's eyes snapped to the source of the sound just as the Zero Pointer's head caved inward, its massive body swaying like a felled tree. 

Yami caught a glimpse of a green-haired kid—Midoriya—hanging mid-air, with his fist broken at an impossible angle and glowing.

'Oh, that hurts', Yami thought, remembering his training and how that particular angle hurt like hell since the bone didn't entirely cut the skin but made a mess through the muscles.

As the robot began to collapse, Yami couldn't help himself, "Shit," he cursed.

Thinking fast, he propelled himself backwards with another rib thrust, narrowly avoiding the falling debris. 

His ribs cracked and retracted again, healing as he flew through the air. The wind whipped against his face, and for a brief moment, he just enjoyed the sensation of weightlessness.

Then he saw Midoriya plummeting like a rock, screaming his lungs out.

"I-I'M FALLING! I'M FALLING!" Midoriya's voice cracked with panic as he flailed helplessly, his body descending faster than Yami's.

Yami cursed under his breath. "Of course, it's him," he groaned.

Yami's ribs shot out instinctively, wrapping around Midoriya's waist and pulling him close. 

Yami hugged the broccoli head tight, holding him against his chest as his entire body petrified to absorb the impact. The air rushed past them as they plummeted toward the ground.

Midoriya's panicked screams filled Yami's ears. "WE'RE GONNA DIE!"

"Shut up," Yami growled. His focus narrowed as he braced himself, turning around to hit the ground with his legs.

Just before impact, Yami felt something soft touch against his back, stopping their descent. 

After a few seconds, Yami continued his fall, but it was slower than when he was at the peak height.

His petrified body slammed into the concrete, sending cracks spidering out from the point of impact. Dust and debris clouded the air around them.

Yami blinked, his golden eyes scanning his surroundings as the dust settled. The ache from using [Open Ribs] throbbed in his chest, and his legs were shattered, his femurs pulverized, but before he passed from shock, Yami instinctively petrified and depetrified his legs, and ignored the pain from his chest.

"You alive?" he asked Midoriya. Midoriya trembled in his arms, nodding rapidly. "Y-YES! Y-Yeah… I think so…"

"Good." Yami unwrapped his ribs from the lettuce hair and shoved him to the side, sitting up with a groan. 

His petrified skin cracked as he moved, bits of black stone flaking off his chest. 

He depetrified his body, letting his natural skin show—only to hiss when the sunlight hit his naked chest.

"AHH! Fuck! Shit." Yami screamed as he looked down, realizing his shirt was completely shredded. The special cream Angela made was long gone, leaving his skin vulnerable to the sun's burning rays.

Without a second thought, he yanked Midoriya's green jacket off him.

"H-Hey!" Midoriya protested weakly.

"Borrowing this," Yami said flatly, draping the jacket over his shoulders and zipping it up. The fit was too tight, but Yami didn't want to walk any longer with his chest petrified, and the jacket covered his chest well enough.

Yami stood up, dusting himself off as he looked around. His sharp gaze landed on Uraraka Ochaco, lying on the ground nearby. Her chest rose and fell rapidly, and her arms were spread wide. She looked exhausted, with her limbs trembling.

Yami approached her, stepping over chunks of debris. "Guess that was you, huh?"

Uraraka blinked up at him, her eyes glassy. "Huh?"

"You saved me some trouble," Yami said. "You put me in zero gravity, right?"

"Oh… yeah," Uraraka mumbled, her lips curving into a tired smile. "Couldn't… let you guys… crash…"

She looked ready to pass out.

Yami crouched beside her and pressed his hand to her forehead. "You're burning up. You used too much energy."

Uraraka let out a weak laugh. "Guess… I overdid it…" she said, closing her eyes slightly.

Yami sighed, shaking his head. "You're no good to anyone like this."

He activated the only technique the system had given him, [Stamina Sharing]. 

As Yami channelled some of his own energy into Uraraka's body, he thought about Angela and how he usually used this technique when she passed out, and her womb was packed to the brink of cum.

Her eyes widened as the colour returned to her cheeks. "Whoa… What are you doing?"

"Helping," Yami muttered. "Relax. You'll feel better in a second."

Uraraka's breathing steadied, and she sat up slowly, her eyes never leaving Yami's face. "That's… amazing. What kind of quirk is that?"

Yami shrugged. "Don't ask too many questions if you want to be happy in life."

Uraraka was a bit stranged by Yami's words, but a soft blush creeed into her cheeks as most of her stamina was already back to her body. "Thanks… You didn't have to do that."

"Yeah, well." Yami stood, offering her a hand. "You saved me some hassle first. Call it even."

Ochako took his hand, her fingers wrapping around his firmly. "I'm Ochako Uraraka. Nice to meet you."

"Iwatani Yami," he said, pulling her to her feet. "Try not to pass out next time."

Uraraka giggled, brushing dirt off her clothes. "I'll try."

Midoriya stumbled over to them, his broken arm hanging limp at his side. "T-Thanks… for saving me too, Ehmm, Iwatami..."

Yami barely spared him a glance. "Didn't do it for you."

Midoriya nodded slowly, looking down at his feet. "Right… Still… thanks."

Yami rolled his eyes. "Whatever."

Present Mic's voice boomed over the loudspeakers. "TIME'S UP, EXAMINEES! THE PRACTICAL EXAM IS OFFICIALLY OVER!"

Cheers and groans erupted from the remaining students gathered in the plaza. 

Medbots and faculty members rushed to tend to the injured, including Midoriya, who was whisked away on a stretcher before an old lady came over and spat on his arm.

Yami watched the chaos with a detached expression. His golden eyes scanned the crowd, searching for familiar faces.

Uraraka tugged on his sleeve, drawing his attention back to her. "You really were amazing out there. You'll definitely make it into U.A."

Yami smirked. "I don't need you to tell me that."

Ochako laughed softly, shaking her head. "Cocky, huh?"

"Confident," Yami corrected.

Ochako bit her lip, her blush deepening. "Well… thanks again. Maybe I'll see you at U.A.?"

"Count on it," Yami said, turning to walk away. As he left, his system chimed in.

[Mission Complete: Help Ochaco!] 

[Reward: +1 Skill Rank] 

[Bonus Reward: You got her attention… but not her number. Tsk tsk, Yami. Slacking off?]

Yami groaned inwardly. "Shut up."

[Hey, just saying. She's interested. Are you gonna let that slide?]

Yami ignored the system as he exited the exam area. His ribs retracted fully back into place, healing his body as he walked. 

His chest ached, and he could feel the fatigue creeping in, but he pushed it aside.

[Well, I better see her fat ass bouncing on your fat cock, or else I'm making you kaboom!]

'Fuck off'

[Ok... Don't be so rash...]

With a loud sigh, Yami walked home after filling out some paperwork. 

The mission was done.

Now, it was time to wait...

...A week later, Yami sat at the dining table with Angela, enjoying a quiet breakfast after a night of fucking non-stop.

Yami went out of his way to ask for some of his points to be given to Midoriya since he remembered that in the original story, he didn't get any points, and in this life, he had left more of an impression in Uraraka than Midoriya.

The sunlight streamed through the kitchen window, illuminating the soft smile on Angela's face as she sipped her tea, naked and with cum leaking her pussy.

"You'll get the results today, right?" Angela asked.

"Yeah," Yami replied, cutting into his toast.

Angela's green eyes sparkled with pride. "I know you did well. I'm so proud of you, sweetheart."

Yami met her gaze, a rare warmth in his expression. "Thanks, Mom."

Angela reached across the table, gently squeezing his hand. "No matter what happens, you've already made me proud."

Yami squeezed her hand back, his golden eyes softening. "I know."

The sound of the doorbell interrupted their moment. Angela stood, wiping her hands with a napkin, and went to her room to put on her kimono. "I'll get it."

After putting some clothes off and wiping her pussy so no cum leaked into the wooden floor, she opened the door, a familiar voice was heard from the street.

An old deliveryman who had been working since Yami was a kid had a package, and he was smiling brightly.

"Delivery for Iwatani Yami! From U.A. High School!"

Angela returned with a sleek white envelope, her smile widening. "It's here!"

Yami took the envelope, his heart pounding in his chest. He slid his finger under the seal and opened it carefully.

A small, round device fell into his palm. The screen lit up, and the image of All Might appeared.

"Congratulations, Iwatani Yami!" All Might's booming voice filled the room. "You've passed the U.A. entrance exam with flying colors!"

Angela clapped her hands together, tears of joy welling in her eyes. "I knew it!"

Yami grinned, his chest swelling with pride. He glanced at Angela, his golden eyes shining.

"Guess I'm officially a hero-in-training."
