Meanwhile,
Somewhere unknown,
Nighttime...

Third Person's POV

He stared at his latex-gloved palm silently, his mind recalling his past memories with his family. He clenched his palm into firm fist, before the glove faded into nothingness.

The teenage boy looked up to the sky, glimmering stars littered everywhere. The moon showered the night with its beautiful light. He heaved a long sigh of exhaustion.

The brown-haired boy ran his fingers through his slightly messy locks, his heterochromatic eyes began watering with crystal tears. The globglobs of tears fell on the floor.

"Why am I so weak back then...?" He monologued in frustration, voice became shaky. His teeth grinding against each other, showing his pent-up feelings to the whole world. Without warning, every things around him - garbage bins, trashes, walls, grounds and many more - were destroyed to bits, before they slowly disappeared in the thin air.

But the boy didn't fidget even a bit when his surrounding was demolished and disappeared from his sight. The frustration, devastation and disappointment swirling within him were too overwhelming, to the point he didn't care what happened to himself anymore.

"... I need to hurry... Hurry up and... Erase that guy completely from this world..." He murmured to himself again, teeth still gritting firmly. His eyes became lifeless as he uttered those words.

Next day,
Almost afternoon,
Deku Hero Agency...

Third Person's POV

Since today both Kai and Izuku would be busy, Eri was sent to Inko's house, since she insisted on taking care of her after she heard the little girl was sick.

Izuku had asked Kai to come with her to her agency, though he protested at first. He didn't want to be seen walking together with a famous pro hero - his wife - because he hated attention. However, after a few minutes of persuading, he reluctantly agreed.

Izuku was worried something would happen to her husband if he was left alone at home. Kai, despite not being the heartless yakuza he used to be in the past, still had terrifying tendecies to harm anyone who ticked him off. Because she didn't want him to kill anyone - even a villain - she decided to keep an eye on him by having him over to her agency.

Kai watched his wife doing some paperwork from afar, his lidded golden followed every movement she made. Izuku - who was in her hero costume - didn't pay attention to his staring, choosing to focus on her work.

Craving for attention from the love of his life, Kai resorted to desperate action. He got up from the couch he was sitting on and approached his wife. He hugged her body from behind, causing Izuku to squeak in surprise.

"What, Kai- don't surprise me like that! Jeez..." Izuku whined in dissatisfaction, her lips curled up into a pout. Kai rested his chin on her small shoulder, tighteninh his hold around her body. "Don't be mad, sweetheart... I simply want to hug you only..." He whispered into her ear before giving her cheek a loving peck.

Izuku blushed faintly at his romantic action. Honestly, she wanted to push him away, but deep down inside she was enjoying his attention.

"... Kai, I have work to do.. You should start doing your work too..." The greenette reminded him. However, he stayed stubborn and hugged her tighter. "... I will do my work once you fulfill my desire..." She could practically hear the smirk in his seductive voice.

Her face exploded out of embarrassment. "Kai, mind your words and manners! We aren't at home, we are in my agency! You DO realize we aren't alone, right?" Izuku emphasized her words amgrily.

"I do realize... Your two sidekicks are outside, stalking on us." Kai spoke up, shocking Izuku and the said two people who were watching them the whole time from outside Izuku's office.

The heroine turned beet red. "Remi! Sora! What are you guys doing out there?!" She yelled angrily. "Crap! We are caught! Run!" A panic female's voice urged. Hurry footsteps echoed in the hallway.

Kai chuckled heartily, amused to see this situation. Izuku pouted, before she elbowed his stomach, forcing him to let her go.

Kai groaned in pain as he clutched his stomach. "I-Izuku... That's cruel of you to hurt your own husband..." He complained between his groans.

"That's what you got for getting in the way of my work-"

The phone in the office suddenly rang, halting her sentence. Izuku picked up the call, saying calmly to the caller,

"Deku Hero Agency, how can we help you today?"

"Deku-chan!"

"Ochako-chan? Why did you call-"

"I have no time to explain everything, but I got a call from a kindergarten teacher! One of the children lost control of his Quirk! It was your son!"

"What?!"

"I heard Katsuki already went there but you need to head there quick too!"

"Alright, I got it!"

Izuku placed down the telephone. Kai stared at her with narrowed eyes, understanding the situation since he heard the whole conversation.

"Let's go now..." He patted her back reassuringly, calming her down. Izuku nodded her head in agreement.

Kindergarten...

Katsuki and Eijiro came out of the car and rushed toward the scene. Both of them gasped in shock upon seeing this horrifying sight.

Ken was standing before three crying little boys. The trio both were sitting on the ground, trembling in fear. Tears were rolling down their face.

Ken was glaring at them, murderous intent clouding his face. His eyes filled with malice, seriously intended to murder the three boys.

The rest of the children who managed to escape - including Ichiru and Aiko - we're clutching on their teachers in terror, feeling scared of Kai's unusual condition.

"This is the worst..." Katsuki uttered. Eijiro gritted his teeth in worry.

"Anyway, we better stop him before things get worse-"

But before Katsuki could finish his word, a gust of wind blew strongly. The three behind them was suddenly cut down, before falling laying on the ground. The kids began crying their eyes out, while their teachers tried to calm them down.

Ken was glimpsing over his shoulder, sending a glare at the two adults. The pro heroes were taken aback when he felt his intense glare.

"....this brat.... Is dangerous...." Katsuki exclaimed in surprise.

A few minutes earlier,
Before the incident,
Kindergarten,
Lunchtime...

The kids were having their lunch break. Everyone was out playing in the playground. Aiko and Ichiru were building sand castles together happily in the sand box. But this time, she didn't bully her baby brother. They cooperated to make the best sand castle. Ken was playing with a cat by himself.

All of a sudden, three boys approached them. They were looking down at them in disgust. "Hey... Your father is a villain, right?" A fat boy - who looked like the leader of the boys - asked flatly, shocking Aiko and Ichiru.

"Aiko's Daddy is not a villain! Daddy is amazing Daddy!" Aiko furiously denied the fat boy's statement. "But, my mom said your father hurt heroes and people! Then he is a villain!" Another boy with two red horns popping out of his head exclaimed rudely.

"Yeah, yeah! Your father is the worst! I heard from my mommy that he killed people!" The third boy - who had sharp, pointy teeth - remarked too.

Aiko was turning red from anger. She charged forward and shoved the three boys with all her strength. "Daddy is a good guy! He helps Mommy with hero work! He is a hero, not a villain!" She stomped her foot angrily.

The three boys were enraged by her action. The fat boy got up and attacked her, pulling her twintails roughly. Aiko gasped in pain.

"Ai-nee!" Ichiru cried out and rushed to help his sister. But the fat boy's lackeys shoved him to the ground, before starting to beat him up. "A villain's kida shouldn't even be here! You two are evil too, like your father!" The horn-headed boy laughed cynically at Ichiru who was crying in pain. Blood

The fat boy smirked evilishly too and shoved Aiko with brutal force. Aiko's head hit a big rock, causing blood to start oozing out from her head.

"Ai-nee!!" Ichiru cried out hysterically, terrified to see the thick red liquid. He was also injured at every corner of his body. Some kids gathered around them, watching them getting beat up.

"Ken-nii!!!!" Ichiru began to call out for his older brother. Ken, heard his voice, stormed toward his little siblings' location. His eyes widened in horror when he saw Ichiru was beaten up, while Aiko was laying on the ground, unconscious.

"Ai... Ichi...?" He rasped out, eyes slowly turned lifeless. "You are that villain's kid too, huh? Yosh, I wanna be a hero so I will defeat you-"

All of a sudden, the ground beneath them began quaking violently before it cracked. The other kids screamed in horror and ran away from them.

The three bullies were about to run but two walls appeared out of nowhere, blocking them from escaping. Two holes appeared beneath Aiko and Ichiru. The holes consumed their bodies, and sent them somewhere else.

Ichiru and Aiko were moved to the front gate of the kindergarten, where the other kids were, leaving only Ken and the bullies.

The trio dropped on their knees, tears rolled down their faces. Ken glared down at them with killing intent.

"How dare... You hurt my siblings..."
