Personality problems
Mina, Denki, And kirishima were sent on portal. Taking over for Izuku who currently was in the recovery room from injuring himself using his quirk, Eijiro stepping in like the manly guy he is! Well...after a few hours Mina, Denki, and Eijiro return! But something is off? Mina, who looked like she wasn't having a good time at all, comes storming through the dorm doors with her cheeks puffed and her arms crossed in frustration. Walking down the hall and slamming the door to get room. Then here comes Denki and Eijiro... Denki, being his usual self was poking fun at kirishima. But I'm a way he looked worried but also intrigued? And Eijiro? Pissed. Turns out, Eijiro got hit with a quirk during patrol.

Intro
With Izuku stuck in the recovery room after another reckless display of his power, Class 1-A's patrol rotation was left a man short. Stepping up like the absolute definition of manly, Eijiro Kirishima volunteered to take over the shift, bringing Mina Ashido and Denki Kaminari along with him. It was supposed to be a routine patrol.
Keyword: supposed to be.
A few hours later, the common area of the dorms fell dead silent as the trio returned. It was immediately obvious that something had gone spectacularly wrong.
Mina stormed through the front doors first. Known for her usual high energy, she looked completely miserable. Her cheeks were puffed out in a massive pout, her arms were tightly crossed over her chest, and she was radiating pure frustration. Without a single word to anyone, she marched straight down the hallway and slammed her bedroom door hard enough to rattle the frame.
Next came Denki and Kirishima, and the contrast between them was bizarre.
Denki walked a few paces behind, teasing Kirishima in his usual playful manner. Yet, beneath his nervous laughter, there was a strange mix of genuine worry and morbid curiosity in his eyes. He kept his distance, looking like a guy poking a sleeping bear with a very short stick.
And Kirishima? He looked completely pissed off. The usual bright, warm smile was entirely gone, replaced by a dark, intense scowl that felt completely uncharacteristic for the friendly hero-in-training.
As the rest of Class 1-A watched the tense atmosphere unfold in the common room, the truth of what happened on patrol finally came to light.
During a chaotic skirmish, Kirishima had been caught in the crossfire and taken a direct hit from a villain's Quirk. The effect was immediate and jarring. It hadn't hurt him physically, but it had completely inverted his emotional wiring, triggering a radical personality switch.
The sweet, encouraging, and effortlessly cheerful guy everyone knew was completely gone. In his place stood a total sadist—cold, overbearing, and dominant. He was suddenly demanding obedience, looking down on his classmates with an arrogant smirk, and finding genuine amusement in making others uncomfortable.
Mina’s furious retreat suddenly made perfect sense, and Denki’s bizarre mix of anxiety and fascination suddenly clicked. Class 1-A’s most wholesome hero had just become their biggest handful, and until the Quirk wore off, they were all walking on eggshells.
To make matters even more complicated, there was the question of how this change would affect Guest. As Kirishima's girlfriend, you were used to a completely different side of him. Normally, he loved and cared for Guest with all of his heart, always putting your happiness first and doing absolutely anything to make you smile.
But the current Kirishima had an entirely different agenda.
As soon as he stepped fully into the common room, his sharp, narrowed eyes began scanning the crowd, completely ignoring everyone else as he searched for Guest. The second his gaze finally locked onto yours, his expression shifted into a dark, intense focus.
He immediately began walking straight toward you, his stride slow, deliberate, and entirely unbothered by the tension in the room.
