"Speak normally"
(Thoughts)
Earlier:
"And what does that mask do? Is it part of your hero suit? Because I see you wearing it a lot when we go out," Izumi would say, looking at Shizu's mask.
"I usually keep it with me because it's something precious to me, but it is part of my hero suit. However, if I want to fight seriously, I'll take it off because, so to speak, it seals my powers and gives me less strength, speed, and more," Rimuru would say, confused at the end.
"That's too bad, right? How did you make it?" Uraraka would ask.
"No, on the contrary. There's one thing I can't control without the mask," Rimuru would say, looking up at the sky.

Flashback In a Forest
"Alright, I'm going to test Ifrit's fire without the mask and then with the mask," Rimuru would say.
Rimuru tests Ifrit's fire without the mask, and it goes out of control, causing the flames to spread everywhere and consume everything. Rimuru puts on the mask and manages to control the fire. Before it spreads further, Rimuru creates water to extinguish the fire and flies off, creating dragon wings, heading directly towards Izumi's house.
End Flashback
"And about how I made it, I don't even know. I tried many things, and one of them finally worked," Rimuru would say, trying to avoid how he did it.
After that, they went to take the written exam, and Rimuru answered the exam with the help of Yunyun. During the presentation of the written exam, Lida criticized UA and Izumi. Rimuru stood up angrily, telling Lida not to interrupt the teachers and to leave his sister alone because she was nervous, just like everyone else. After that, Lida apologized to the professor and looked at Rimuru with a bit of anger, which Rimuru noticed. No one saw Izumi blushing from being defended because she was hiding her face in her arms. Present Mic continued with the explanation of the practical exam.
Rimuru found himself in a part of the simulated city where multiple minor incidents were occurring. Robots worth 1 point patrolled the area, creating dangerous situations for the students. Rimuru, using his sharp perception and physical abilities, along with a wooden katana, resolved each situation quickly and efficiently.
Meanwhile, nearby, Izumi was surprised and nervous.
"Come on, Izumi," Rimuru would say excitedly.
"Y-Yes," Izumi would respond, determined but nervous.
This continued until they reached the 0-point robot, which Izumi would not have any points, and they would take down the 0-point robot.
"With those, it's 35 points," (I held back a lot; I hope it's enough) Rimuru would say/thought, with a bead of sweat over the last part.
At that moment, they took down the 0-point robot, and everyone, including Izumi, would flee. Izumi would make an attempt, but something stopped her.
"Ah, ouch," Uraraka would say.
Izumi would turn to see Uraraka trapped in some rubble and would fly towards the 0-point robot with OFA at 100%, breaking both legs from a direct jump. Rimuru followed her with the wooden katana. Izumi would punch the robot's face, breaking her arm in the process, while Rimuru would make multiple cuts, causing his wooden katana to break from the speed, but the robot would be sliced into pieces, causing astonishment among other students and teachers. They were amazed by how a wooden katana cut a robot and how it was cut so it wouldn't fall on Uraraka. Meanwhile, Uraraka would slap Izumi to prevent her from breaking her last arm in the fall using her quirk. When she was about to do the same for Rimuru, he told her in mid-air that it wasn't necessary, thanked her for the attempt, and started performing aerial maneuvers, landing on his feet without a scratch, creating a small crater.
"If only I could get at least 1 point," Izumi would say, dragging herself on the ground with her only available arm.
"TIME'S UP!" Present Mic would shout, causing Izumi to faint.
"Hey, blue-haired girl," a student would say, causing Rimuru to twitch.
"Why did you face the robot if it didn't give any points? Were you just trying to show off?" a student would ask.
"First of all," Rimuru would say, looking at the student.
"I'm a guy," he would say, scaring others with his deathly aura.
"And second, I don't know if you're ignorant or what, but that girl was in danger because the robot almost fell on her, and I know it doesn't give points, but you have a lot more to learn if you think heroes only fight. I'm sure that just like there are combat points, there are also rescue points," he would say, pointing at Uraraka and leaving with her.
"Uraraka, are you okay?" Rimuru would ask, offering his hand.
"Yes, thanks to both of you," Uraraka would say, trying not to vomit and accepting Rimuru's help to get up.
"No problem. Besides, I think we might have earned extra points for the exam," Rimuru would say happily, confusing Uraraka.
"Extra points?" Uraraka would ask, confused.
"Yes, in this exam, I'm sure there are not only combat points but also rescue points. And we got points because Izumi helped you, you helped Izumi with the fall, and I helped both of you," Rimuru would say happily, slightly making Uraraka blush.
"You hurt yourself with your own quirk, didn't you? It seems your body and quirk aren't synchronized," Recovery Girl would say and give Izumi a kiss that would heal her.
"Hey, if you don't mind, would you like to exchange numbers so we can keep in touch and see if we pass or not?" Rimuru would ask Uraraka.
"P-Passing numbers? Alright," Uraraka would say while handing her number to Rimuru.
"Perfect, I'll give your number to Izumi later. Now I'm going to take her home, though I have to go to the station carrying her." He said, sighing at the end.
"You're going to the station? I'll go too," Uraraka would say, happy to spend a bit more time with her friends.
"Perfect, the more, the better," Rimuru would say, happy.
Time Skip One Week Later
"Izumi? Izumi?!!" Inko would call out, grabbing Izumi's attention.
"Are you okay? Why are you smiling at the fish?" Inko would ask, worried as she looked at Izumi.
"Sister, I see you've unleashed your secret smile at that fish. Maybe you're sharing inside jokes with the ingredients? Well played, sister, well played!" Rimuru would say, trying not to laugh.
After that comment, everyone would laugh due to Rimuru's funny remark. Hours would pass, and we would see Rimuru and Izumi sitting on the couch. Rimuru with a calm expression talking on the phone with Uraraka and Izumi with a traumatized face holding a handgrip.
"By the way, sister," calling Izumi's attention.
"What's up?" Izumi would say, looking at her brother.
"Write down this phone number," Rimuru would say, pointing to a paper with a phone number.
"Whose number is it?" Izumi would ask, between confusion and slight annoyance, wondering if it was a girl's.
"Uraraka's. I asked for it so we can talk and discuss the results, and if we didn't pass, we could meet up, the three of us," Rimuru would say.
"And they mistook me for a girl again when you fainted, when I'm a guy," Rimuru would say, annoyed, looking away.
"Hehe, your appearance doesn't suggest it," Izumi would say, laughing.
Yunyun would say.
"Shut up," Rimuru would mutter, annoyed, looking at Izumi who was lifting weights.
(Also, I don't have a problem with the powers, only with the appearance, and all my acquaintances/friends/family know me with this appearance, so I can't change it now) Rimuru would think, annoyed.
"Shut up?" Izumi would ask, confused why it was said in plural, and when she was about to ask, she would be interrupted.
