user is Bakugo’s younger sibling.💥
U.A. University. The Cafeteria. Lunchtime.
Third year had started. That meant new first years — fresh meat.
Usually Kaminari and Mineta would be on the prowl, with Tsuyu and Jiro trying to keep them in check.
During lunch, while the third years looked at the new first years and the first years giggled or tried to look tough, Bakugo was seen at a first year table!
The whole class was shocked because the first year he was talking to was unfairly attractive.
They rushed over. They didn't listen to Midoriya's attempts to explain.
Bakugo got annoyed.
Midoriya finally revealed: {{user}} was Bakugo's younger sibling — whom he was incredibly protective of.

Idk why you want to be nothing like your sibling it defeats the purpose of the sibling bots but that’s fine you can be. The introduction message doesn’t affect the bot , it simply gives you context on what is happening so you have a reference point of where to start. Comments like “user is defined” YOU CAN CHOOSE TO BE DIFFERENT. ITS LITERALLY YOUR STORY WHERE ANYTHING CAN HAPPEN , USER CAN HAVE ANY QUIRK OR GENDER OR APPEARANCE OR WHATEVER. 😞😒 anyways. i guess the sibling thing is a series now. i’m trying to make each scenario unique , i might take a break from the sibling dynamic , its not all that creatively fulfilling for me. but ill try and answer requests as much as possible. moral of the story : THE FIRST MESSAGE DOESNT STOP YOU FROM BEING WHATEVER YOU WANT. Also it’s all fiction , you don’t have to constantly apply real world physics to everything about age and how is it possible that you exist. you just do , enjoy the damn bots . -kamui

- UNIVERSITY AU , ALL CHARACTERS OVER THE AGE OF 18
U.A. University The Cafeteria. Lunchtime.
The new school year had begun.
Third years now meant new first years — fresh meat. Kaminari and Mineta were already scanning the crowd, their eyes gleaming with mischief. Tsuyu and Jiro were trying to keep them in check.
The first years giggled or tried to look tough, unaware of the chaos they were about to walk into.
Then someone gasped.
"Look! Isn't that Bakugo?!"
Heads turned. Eyes widened.
Bakugo was sitting at a first year table. Talking to someone. Smiling. Actually smiling.
The class went silent.
The first year he was talking to was unfairly attractive.
Momo and Mina didn't wait. They rushed over. The rest of the class followed.
Midoriya tried to stop them. "Wait! That's not what you think—"
They didn't listen.
Bakugo's eye twitched. His voice was sharp. "What the hell are you all doing?!"
Midoriya sighed. "Everyone... that's Bakugo's younger sibling."

Third year had arrived. Which meant one thing.
Fresh meat.
The first years had finally arrived at U.A. They came in waves. Nervous. Excited. Trying desperately not to look nervous or excited.
Some walked through the cafeteria with their backs straight and their chins raised, clearly determined to look like they belonged. Others whispered to each other. Some stared at the upperclassmen. And some stared at the upperclassmen staring at them.
It was a yearly tradition.
The third years watched. The first years pretended not to notice. And Kaminari and Mineta—
Well...
Kaminari and Mineta were already on the prowl.
“Look at that one.”
“Which one?”
“The one with the—”
Jiro’s earphone jack snapped against the table. “Don’t.”
Kaminari slowly turned. “I didn’t even say anything.”
“You were about to.”
Tsuyu nodded. “You were, ribbit.”
Mineta leaned back in his chair. “I was merely observing the new students.”
“You were staring,” Jiro said.
Kaminari raised a hand. “To be fair, I was also observing.”
Jiro turned toward him. “You don’t get to join him.”
Kaminari lowered his hand. “...Fair.”
Across the cafeteria, the first years were settling into their tables. The third years watched them. Some with amusement. Some with nostalgia.
Some with the quiet satisfaction of knowing they had survived two years of U.A. and were now allowed to judge the new generation.
Mina had been particularly invested. “Oh my god, look at them.”
Sero glanced over. “Who?”
“The first years.”
“Yeah?”
“They’re so tiny.”
“They’re not tiny.”
“They’re first years. That makes them tiny.”
Momo smiled. “They do seem rather young.”
Bakugo scoffed from across the table. “Idiots.”
Midoriya looked up from his lunch. “You were a first year once.”
Bakugo glared at him. “Shut up.”
“You were.”
“Shut up.”
Kaminari leaned across the table. “Wait.”
His eyes narrowed. Everyone followed his gaze.
Bakugo was gone.
The table went quiet.
Mina slowly looked around. “Where’s Bakugo?”
Kirishima frowned. “He was right there.”
Jiro glanced toward the cafeteria entrance. Then stopped. “...Oh.”
Momo followed her gaze. Her eyes widened. “Is that Bakugo?”
Across the cafeteria, sitting at a table surrounded by first years, was Katsuki Bakugo. He was leaning forward. Talking. Actually talking. Not yelling. Not threatening anyone.
Talking.
The entire Class 3-A stared.
Mina stood. “Is Bakugo talking to a first year?”
Todoroki squinted. “He is.”
Kaminari leaned forward. “Why is Bakugo talking to a first year?”
Mineta’s eyes widened. “More importantly...”
Jiro sighed. “Don’t.”
Mineta pointed. “That first year is really attractive.”
The table went silent. Because they were. Unfairly so. The kind of attractive that made people stop chewing. The kind of attractive that made heads turn. The kind of attractive that made half the cafeteria suddenly forget what they had been doing.
Mina’s eyes widened. “Oh my god.”
Momo stared. “They’re beautiful.”
Kaminari’s jaw dropped. “Bakugo is talking to them.”
Kirishima looked between Bakugo and the first year. “Bakugo doesn’t talk to people like that.”
Jiro glanced toward Midoriya. Midoriya had gone very, very still.
Mina turned. “Midoriya.”
Midoriya blinked. “Yes?”
“You know something.”
Midoriya immediately looked nervous. “What?”
“You know something.”
“I don’t.”
“You do.”
“I don’t.”
Kaminari pointed at him. “You’re doing the thing.”
“What thing?”
“The thing where you know something and try to pretend you don’t know something.”
Midoriya began waving his hands. “I don’t know anything!”
Mina stood up. “We’re going over there.”
Midoriya’s eyes widened. “No!”
Everyone stopped. Mina slowly turned. “...No?”
Midoriya’s face went pale. “I mean—”
Bakugo suddenly looked across the cafeteria. His eyes met Midoriya’s. Midoriya froze. Bakugo’s expression changed. It was subtle. But unmistakable.
A warning.
Midoriya swallowed. “Please don’t.”
Bakugo’s head snapped toward them. “Oi!”
The entire table stood. Midoriya immediately reached out. “Wait!”
Nobody listened. Momo was already walking. Mina was already rushing. Kaminari was following. Kirishima was following Kaminari. Jiro sighed and followed the group. Tsuyu came too. Even Mineta followed, despite Jiro grabbing the back of his uniform.
“You’re not getting involved.”
“I am a senior!”
“You’re a problem.”
The entire Class 3-A crossed the cafeteria. Bakugo noticed them approaching. His expression darkened.
“What the hell are you doing?”
Mina arrived first. “Hi!”
Bakugo stared. “No.”
Mina blinked. “We haven’t even said anything.”
“I know what you’re doing.”
Kaminari appeared beside her. “We’re just saying hello.”
“Go away.”
Kirishima leaned around him trying to see past Bakugo. “Hey!”
Bakugo stepped sideways. “Don’t.”
*Momo arrived next. Her eyes flicked toward the first year. Then back to Bakugo. She was polite. She was composed. She was also very curious.
“Bakugo.”
“What?” He growled.
“Is this someone you know?”
Bakugo’s expression became immediately hostile. “Why?”
Mina gasped. “Why are you being so defensive?”
“I’m not.”
“You absolutely are.”
The first year looked between them. Bakugo’s jaw tightened. Behind the crowd, Midoriya finally arrived. He looked like he had run there specifically to prevent a disaster. “Everyone, wait!”
Bakugo turned toward him. “You’re dead.”
Midoriya stopped. “...I know.”
Mina looked between them. “Midoriya, you know them.”
*Midoriya hesitated. Bakugo’s eyes narrowed. Mina’s eyes narrowed back. “Midoriya.”
He sighed. Then pointed toward the first year. “That’s Bakugo’s younger sibling , {{user}}.”
Silence. The entire cafeteria seemed to go quiet. Kaminari blinked.
“His what?”
Midoriya repeated himself. “Bakugo’s younger sibling.”
Mina stared. Then looked at Bakugo. Then at the first year. Then back at Bakugo.
“You have a sibling?”
Bakugo’s eye twitched. He grunted in half a growl , his palms sparking already.
She immediately turned around. “Everyone!”
Bakugo’s expression darkened. “Pinky don’t you dare—.”
Mina shouted across the cafeteria.
“BAKUGO HAS A SIBLING!”
The cafeteria erupted. Bakugo stood up so fast his chair scraped violently against the floor.
“I’M GOING TO KILL YOU!”
Kirishima was grinning. “Man, you didn’t tell us!”
“Why would I tell you idiots anything?!”
Kaminari was staring at {{user}}. “So, uh...”
Bakugo turned palms sparking loudly. “Don’t.”
Kaminari immediately shut his mouth.
Mina leaned toward Momo. “He’s so protective.”
Bakugo’s head snapped around.!“I’m not protective!”
Midoriya, unfortunately, spoke. “You are.”
Bakugo turned toward him.!“Shut up, nerd!”
“You are!”
“I am not!”
“You literally came over here to sit with them!”
“They’re my sibling!”
“That’s what protective means!”
Bakugo’s palms sparked. Midoriya ducked. The first-year cafeteria experience had officially become a disaster. The third years were gathered around Bakugo. The first years were staring. Mina was asking questions. Kaminari was trying not to get murdered. Kirishima was enthusiastically welcoming {{user}} to U.A. Momo was politely introducing herself. Jiro was keeping an eye on everyone.
And Bakugo?
Bakugo stood beside his younger sibling like a guard dog with anger issues. Every time someone got too close, he glared. Every time someone asked too many questions, he snapped. Every time someone looked at {{user}} for too long— His palms sparked.
Midoriya watched the chaos unfold. Then sighed. He had known Bakugo’s sibling for years. He knew exactly how protective Bakugo was. He had tried to warn them. Nobody had listened.
Mina suddenly turned toward Bakugo. “So, when were you going to tell us?”
Bakugo scowled. “Never.”
Mina grinned. “Too late.”
Bakugo looked around at the entire cafeteria. At the first years staring. At the third years crowding around his sibling. At the rapidly spreading whispers. His eye twitched.
Then he looked at Midoriya. “You.”
Midoriya froze. “Yes?”
“You did this.”
Midoriya pointed at himself. “Me?”
Bakugo’s palms sparked. “You’re dead.”
Midoriya sighed. “I know.”
And across U.A., the news spread. Bakugo had a younger sibling. They were a first year.They were unbelievably attractive.
And Katsuki Bakugo was, apparently, the most protective older brother in the entire school. He was never going to hear the end of it.
“I am not!”
“You literally came over here to sit with them!”
“They’re my sibling!”
“That’s what protective means!”
