"So.." Katsumi started, trying to break the awkward silence.

"Don't even try it." Katsuko grumbled killing any possible conversation.

Katsumi just sighed sadly before pulling out an old picture.

"Don't you think it's odd that we both look exactly alike. The only difference is our hair colours." She said as she continued to look at the picture intensely which made the ash blonde a bit curious at what she was getting to.

"What do you mean? I thought your quick was to copy people's face and you just enjoyed copying mine because you wanted to annoy me." Katsuko voiced out her thought which made Katsumi scoff.

"Don't be stupid. I already told you that I don't have a copying quick and even if I had it, why would I want to copy your ugly face. Plus I have been fighting you with my crystal explosion. You really are an idiot." Katsumi fired which made the other girl also let out a scoff.

Katsuko could feel her blood start to boil and she wanted to attack the white haired girl but she decided not to because she didn't want to get into more trouble and her mom would also kill her.

"You are calling me an idiot when you basically called yourself ugly. We look alike peabrain. If I'm ugly you are ugly. Also don't ever call me an idiot or else." Katsuko fired back which silence Katsumi.

She really should have thought about her words. A awkward silence followed but this time Katsuko was the one to break it.

"Your quirk, explain it to me." She said as she extended her hand to play with the water below her.

Katsumi looked a little shocked but soon smiled.

"Well I can make explosions but instead of them being fiery they come out as an ice crystal. I don't know how to explain it further." She responded which made Katsuko stop playing with the water.

"Your quirk is kinda cool. It's actually like my mom's. She can make ice crystals but they don't explode like yours." She explained which made the other look at her curiously.

"Wow, you know your quirk is also actually similar to my dad's. He can also make explosions. He is actually a hero back in Japan. I want to be a hero just like him." She said with a small smile.

"What's his name?"

"Well his hero name is Dynamight and his birth given name is Katsuki Bakugou." She said which made the other girl gasp but she tried to cover it up with a cough.

"Wait... Bakugou? Are you sure?" She asked.

"Of course I am sure. He is my father after all." Katsumi scoffed.

"What's your name?"

"Wait you don't know my name after all these days?" Katsumi asked.

"Well you don't know my name either and why the hell would I care about a damn extra's name?" Katsuko scoffed while rolling her eyes.

"No need to be rude ok... Anyway my name is Katsumi Bakugou." She responded proudly which made Katsuko gasp once again but this time she did not try to cover it up.

"How can your names be so similar to mine? How is it such a coincidence that we look alike and have almost the same name?" Ko questioned as she tried to understand it.

"W-well what's your name?" Katsumi asked looking back down at the picture in her hands.

"Katsuko Bakugou-Cruise." She responded and Katsumi almost fell out the boat from pure shock.

"When's your birthday?" They both asked at the same time.

"First September." They both responded and when they got their answers they just looked at one another.

"D-do you have a father?" Katsumi hesitantly asked.

"No."

"S-so... So you don't have a father and I don't have a mother. T-this can't be a coincidence... I have an old picture of my mother that my dad gave me. Do you have a picture of your dad that your mom gave you?" She asked as she looked back down at the picture in her hand.

Katsuko nodded before pulling out the picture that she never left the house without. She also had one of her mother.

"Yeah. But mine is a pathetic little picture. It was torn right the middle." She said before looking at the old photo of her father.

She hesitantly moved closer to Katsumi and reached out her photo while Katsumi did the same with her's. The picture slowly connected and both girl's couldn't help but to gasp.

"That's my mom."

"That's my dad."

They both said at the same time and looked at the picture for a few more seconds before turning to look back at one another.

"So this means we are twins?"

"Yep!"

The both then sat in silence as they tried to process the information that they had just recieved.

It was shocking that they both spent the last eleven years without knowing that they had a sibling.

Katsuko opened her mouth to say something but was interrupted by the voice that rang through the air.

"KATSUMI BAKUGOU AND KATSUKO BAKUGOU-CRUISE! IT'S TIME TO GET OUT THE WATER. YOUR PUNISHMENT IS OVER!" Shinso's voice said making both girls roll their eyes.

They both began to row back to the pier silently.

"What does mom do?" Katsumi asked as both girl walked back to the camp.

It was also surprising that Katsuko had stayed so calm.

"She also used to be a hero but now she is a fashion designer. Grandpa also works with her." Katsuko explained.

"Do you mean grandpa Masaru?"

"Ya, he basically lives with us now which is actually not as bad as I thought it would be at first." She responded truthfully.

"I get ya. Dad and I also live with grandma Mitsuki and uncle Ei. He is my partner in crime. We are always pranking dad which he totally hates. Come to think of it you basically have the same personality as dad." Katsumi said with a little giggle which made her sister just stick out her tongue at her.

The two continued to get to know each other until they got two the cabin where Katsuko pretended like she wasn't just soft a few minutes ago.
