....

Once upon a time, to a life where everything is a wonder ; a series of  unexpected events. A boy with a green hair that is partnered with some black color with it, named Izuku Midoriya, was running excitedly to approach his friend ; Kacchan.

"Kacchan!" The boy caught his attention with him turning. "Deku! You're almost late!"

The boy ; Izuku, rests his hands in his knees as he was panting to catch his breathe. "S-sorry! I was just so excited about tomorrow!" He apologized as he gave Kacchan a smile. "Excited? For what? There's nothing special." Kacchan shrugged.

Izuku shooked his head. "No! My lil' sis is coming tomorrow!!" He yelled in excitement at the thought of his sibling tagging along. It was like the same excitement with All Might's, but more emotions rised than his excitement to his idol.

The thought of telling her how cool it is, how nice.

"Lil' sis? Heh, I didn't knew you have a sister, deku!" Kacchan huffed. "S-sorry." He smiled sheepishly. "Well then! I bet she is amazing unlike you who is pathetic for his whole life!" Kacchan laughed as their peer was about to come.

Izuku became depressed. He knew, yes, he was pathetic.

But he didn't let that came over him as he thought about you and he beamed. He let that thought slide away.

"That's not true!" He said, but Kacchan was about to retort, and again their peers came and Bakugo started off their adventure.

'A sister , huh? I bet she's ashamed about her brother' kacchan thought.

＊ The Next Day ＊

Kacchan waited for his playmates. And as he saw someone familiar, he called. "Deku! You're unexpectedly early?" He questioned. "Y-Yeah...I got excited hehe." He admitted.

Kacchan saw his other hand holding someone's hand. Revealing another green haired kid. She was smaller of course since she was young. She was really nervous about meeting another kid, and another thing, he was a boy.

"N-nii-chan..." The younger green haired girl tugged onto her older brother's arm. "Don't worry Izuchan! Kacchan is kind! Kacchan this is Izuki, Izuchan this is Kacc-err Katsuki!" Izuku introduced the both of them to each other.

"Nice to meet ya!" Kacchan held his hand for Izuki to take. Izuki, nervously took his hand and shaked it. "N-nice to m-meet you t-too, K-Kacchan." She beamed a smile, but a nervous one.

"Oi don't call me that! No fair!" Kacchan pouted. "E-eh? What do you mean?" Izuki asked shocked. "You give deku a proper nickname! You should give me too!" He continue to protest.

"B-but I don't know...." She became embarassed. "Izuchan, sorry! I have to go help mom while you stay with Kacchan!" Izuku dissapointedly excused himself. "B-but—" then Izuku interrupted her.

She sighed.

"Sorry Kacchan! It's really an emergency!" He ran.

They were left there speechless.....

.....

"Y-you know Kacchan—"

"Don't call me that!" He sternly growled. "S-sorry, but until then I would call you that!" You gave him a goofy grin. He was shocked of how fast your personality changed. "Tch, YOU LITTLE—"

Not used to deal with people, you panicked and quickly bowed clutching tightly on the hem of your clothes. Eyes are closed tightly as well. "S-s-sorry!!!" You apologized nervously.

He stood there, shocked at this. "Tch don't apologize." He said then walked off.

"W-where are you going?" You asked curiously as you regained your posture. He turned to you with a grin. "I'm going to an adventure where I'll venture the forest! And kill monsters in there with my quirk!" He said proudly as cracks of explosions emitted from his hands.

Your eyes was glistened with admiration. "Wow! Amazing!!" You squealed as you run near him with your eyes with stars and your hand in a position like Izuku's when he gets excited. He smirked at the praise.

"C-can I come?????" You asked with puppy eyes. Kacchan blushed.

'Damn your cuteness, stop with those puppy eyes shi—ugh!'
He shrugged the thought.

"S-sure! Just don't get in my way!" He said. Izuki nodded her head vigorously.

As the too kids marched forth to the forest, Kacchan bragged on about this Bakugo hero agecy thing, while the other younger one listened and supported.

While marching, something caught Kacchan's interest.

"Hey shorty, how 'bout we go on a cave adventure?" He turned to his companion with a grin. "Cave adventure?" You asked, ignoring the nickname. "Over there!" He pointed to the cave that was just far across the river. By crossing the river, you need to follow the path towards it then boom! You reached the destination.

"In there, there are many beasts and scary monsters awaiting! It is also dark and spooky.." Kacchan stated, with a smirk and grim expression, trying to scare the girl away. The greenette was taken aback by this, for you are scared of the dark. Kacchan noticed this, and expected a scared response.

The girl decided to speak. "S-sure! I am e-excited now!" She wavered, it was obvious she wasn't. Kacchan was shocked at how her personality.

He nodded nonetheless. "Then let's go!" He cheered as the young girl followed behind happily but nervously. They crossed the river, Kacchan just stepped on the rocks easily, while the other one is having a hard time to prevent herself from slipping.

After crossing the river, they somewhat instantly got to the cave's entrance. Izuki was panting, while Kacchan, well as usual, no effect. "Here goes nothin'" he said as he started to take a step in.

You were too caught on the butterfly that you saw. You followed it as you didn't noticed where you were. Kacchan abruptly stopped on his tracks and looked back to spot you.

But unfortunately, you weren't there. He was worried a bit. 'URGGHH WHY AM I EVEN WORRIED?!' He mentally slapped himself. "Besides, I don't know why am I even worrying.." He started. He ran out of the cave and started to search you. "IZUKI! WHERE THE HELL ARE YOU?!" He yelled through places.

But...it was useless.

"AGH!!" A scream screeched through the forest, as Kacchan perked up at this.
"IZUKI!" He quickedly sprinted towards the source of voice. Tracking the direction using his instincts.

As soon as he saw you, he eyes widened at this. He quickedly went near you.

Omg....

How terrible....

"Jesus christ it was just a fricking PLANT!!" Kacchan yelled as he knocked her head. "Oww.." She winced. "Sorry, Kacchan...." She apologized. While Kacchan can't be mad at her at a long time. He sighed. He didn't responsed back and just grabbed her away.

They went back the cave. "Just....don't get lost, or I won't be able to face deku!" He said. You nodded. You smiled a bit, since he got worried, like man, how fast this escalated quickly, joke.... it's just the start of affection.

You and Kacchan walked in the cave, testing your courage. "K-Kacchan, don't we need a flashlight? I hate the dark.." You asked.

"Pffttt-- only weaklings need that crap." He mockingly said. "But it's dangerous! Anything c-can happen unexpectedly- " hearing twigs snap, you were paranoid and held tightly on Kacchan's arm. "Tsk, go back? You can do that all you want and be pathetic for your life, dummy." He said.

You shooked your head. "If y-you say so..." You gave up and just held onto him as you guys explored the cave. Just simple things are present.

And luckily, he stopped. "It seems it's boring here, there are no monsters! Mission accomplished." He proudly said, and a bit irritated because he didn't have time to show off. But, it was to assure you. "Let's go back now." He stated and you nodded. Again, life is a series of unexpected events.

Suddenly, a hand grabbed you from him and separated the two of you. "IZUKI!" His eyes widened as his hand attempted to reach you. Your hand reached as well, but it was no use. It came to the time where darkness was all around you and you couldn't see Kacchan.

You noticed the hand that grabbed you was cold, and it only had four fingers holding your hand.

"I'm sorry I have to do this." A raspy voice, but you somewhat found attractive, spoke.

You turned to the guy- or you assumed to be the one who was a lot older than you earlier. He had a ligh blue hair, you and him had met each other's eyes. His eyes were red, like Kacchan's.

"U-Uhm..." You nervously started. And there, were it clicked.

"Ah! You're the boy from earlier! Tomura-san, right?" You asked nervously, but lit.

He removed his hand from yours. "Yeah..." He responsed back.

"What are you doing here? I thought you left me.." You asked a bit dismayed about him leaving you.

"That friend if yours already got you, besides, I don't want to disturb that momentum." He said nonchalantly. "O-okay, what did you want from me? Why did you separated us?" You asked him desparately.

"That place is dangerous for a kid like you. Besides, I have someone for you to meet." He said, a smirk creeping out of his faces. This caused the girl to flinch. "B-bu-b-but...what about Kacchan??" You asked somehow worried.

"He'll be fine, I already had someone to take him out of there." He assured you.  Being the kid you were, you were easily convinced and just nodded and let him take to this 'person'.

.......

But in all honesty.....
That was the last day, that you were seen.
