One-off short stories

The Adventures of Sky Endo (dangansquad edition)

I'm having this take place freshman year, even though I was inspired by the scenario in senior year.
--------
"Sis, I've been thinking about something exciting!" Sky said, smiling. She had an idea she thinks will work.
"Huh, what is it? You want to go off exploring again?" Aiko asked.
"No, no, nothing like that! I just, want to be less shy. But I think I know how I can do that. I've figured it out!" Sky said excitedly.
"R-really?!" Aiko sounded excited too. It was rare her sister would be so happy and upbeat over something like this.
"I just have go to school being a superhero!" Sky said.
"Wait, wha---?" Aiko was a bit confused.
"If I'm a superhero, and I'm not showing my identity as Sky Endo, but then I could be whoever I wanted
to be. And that hero wouldn't be shy!" Sky said.
"Oh, ummmm," Aiko thought for a while,"That, could work. But isn't it better if you try to get over your shyness by being yourself?"
"I don't think I could, to be honest. At least not yet. But becoming some kind of masked hero! Then I'm sure that will help me." Sky said, she clearly had her heart set on this idea.
"There's no way I could argue with you when you're this persistent." Aiko said,"So, let's go make you a costume."
--------
"To call upon the powers of friendship and love...I, the hero Scarlet Heart have arrived!" Sky struck a pose. She'd been practicing being a hero in front of a mirror for a while now,"No, that's not good enough. Come on, Scarlet, think! Hmmmmm. Hmmmmm."

"To save a world distraught in pain, one girl comes from the Sky to help everyone! That is, me! The hero Scarlet Heart!" Sky struck a different pose,  thinking for a moment,"No, that's no good either. What should I do?"

"Argh! This is hard. Come on Scarlet, don't try so much. Just be a hero. Let it flow." Sky told herself.

"Soaring through the night sky and walking through the day. One hero is here to make the whole world smile. That is me, Scarlet Heart! The Ultimate Superhero of Hope's Peak Academy!" Sky struck one last pose,"Perfect! She looked down at her costume. She'd taken off her binoculars, she didn't need them as a hero. And was wearing a slightly fancy red shirt and skirt. She also had a pair of glasses on. In other words, she was completely recognizable. But Sky and Aiko didn't quite have enough money to buy her a costume that actually disguised her. So Sky was counting on using her superhero skills to act in a way nobody could tell it's her.
--------
"Everyone." Aiko said, at the start of class,"You might notice Sky isn't here yet. Which is strange, because we almost always arrive at the same time. But, um, when she shows up. Please, let me ask a favor of you. Act like you can't tell who she is. You'll know what I mean when you see her."

Rives also said,"Yes, if you just called her Sky. She'd probably break down. She's trying something new. Be accepting of her."

Sky, I mean Scarlet, stood outside the door, fixing up her glasses. It's just your classmates. It shouldn't be too hard. You're a hero, remember! Yeah! A hero! She slammed open the door. Alright then, now superhero entrance speech, go!
"Soaring through the night sky and walking through the day. One hero is here to make the whole world smile. That is me, Scarlet Heart! The Ultimate Superhero of Hope's Peak Academy!" Scarlet said, and smiled, taking a pose.
The classroom was shocked into silence. It was so obviously Sky it was pretty much funny. But Aiko and Rives clapped, and basically forced the rest of the class to go along with it for the day.
Still, Scarlet was having a ton of fun. She talked to everyone, and tried to help them, and was clearly enjoying herself. At least, so long as nobody mentioned the name Sky. But she did almost feel like a classroom superhero. At least, compared to how she usually was.
--------
Sky sat down on the couch back at home,"That was tiring." She said, taking off her glasses.
"Still, you had a ton of fun, I could tell." Aiko said, smiling.
"Yeah! I might do that some more. I didn't buy that costume to only use it once!" Sky said.
"Oh no..." Aiko muttered. She was more worried about what would happen once one of them accidentally spilled the beans that it was obvious who they both were.

From that day forth, sometimes Sky showed up, and sometimes Scarlet Heart showed up to school. And sure, everyone knew who she was. But she always had so much fun, nobody wanted to tell her that. So Scarlet Heart's real identity became a closely kept secret. Not by Scarlet herself, but by the friends who saw the obvious truth.

--------
I haven't written something plain fun like this in a while. It's nice every now and again. Now I kind of want to use this idea in a scenario somewhere.
