The leader of the Blizzard Group. B-Class, Rank 1. The Blizzard of Hell. Fubuki was known through quite a few feats and titles of hers, which she was proud of. Sure, not so proud that she would shoot for A-Class, but still felt a sense of accomplishment.

With the help of her companions, who she knew she would become strong alongside, it was only a matter of time before they gained even more recognition in the public eye, able to sway even the greatest of heroes to her side. Like flies to honey, they would flock to her.

These psychic powers of hers? They were a great gift. They were what had empowered her to get to such a position. To become stronger. To help people. To help herself. They were what enabled her, along with her great social charisma, to earn the respect and friendship of her group.

And they were just as great a curse. She was too young to remember; only 2 at the time, really. While she had gained some form of consciousness, considered a little early for some children, but as a psychic it was much quicker for her (even if the powers hadn't awakened), the memories were blurry. She would only remember vague instances where her older sister was ripped from her to be experimented on.

Those vague instances of Tatsumaki being taken away from her, of her parents crying and trying to comfort each other while looking at family pictures? That's what stuck every now and then. It wouldn't be so horrible if she could just remember it all; it was the fact that she didn't remember it all that hurt, because there was this void that she just. Couldn't. Fill. Those memories are what Fubuki cursed, because that's what tore the bond between herself and Tatsumaki for so long.

And even though this bond had eventually become quite a little bit better, with this one bald man deciding to show Tatsumaki that she, in fact, was not the strongest other than Blast? It was admittedly quite strained. They weren't like other siblings, who could talk shit to each other with a smile on their faces. They weren't like other siblings, who would, despite hating each other's guts, hold close love and affection and communication.

They were siblings, and that was about it. Hell, she couldn't even remember the last time she and Tatsumaki had had dinner together, just as a family!

Well, she guessed she'd have to accept the slight progress. It was this bald man who had started to mend their relationship, and it wasn't like she was strong enough to force him to do more.

It was extremely unfortunate that this bald man would end up making herself and Tatsumaki interact in the worst way possible, especially through the thing Fubuki cursed most: her own powers.

1 a.m. It was quite literally the dead of night. Some night heroes are out on patrol, but not Fubuki. She needed her beauty sleep. Plus, heroes who only did night patrols never got popular; how the hell would they? Nobody ever saw their deeds.

She had run through her nightly routine, gotten ready for bed, and even did some evening checks to see what public opinion of the Blizzard Group was like at the moment. It was necessary. How else were they supposed to bring in more support and money if they weren't on top of what people wanted or needed from them?

Hell, she had even read a little bit of this one book that she had recently gotten interested in, recommended to her by Lily! It was pretty nice, though she had to admit that action wasn't really her style when she lived it every day.

But now? She was well asleep. It was time for her to get some rest. She always went to sleep no later than 11 in the evening, and ensured that she got at least 8 hours of sleep. Unsurprisingly, because of how much espers used their minds, they typically also needed more rest than other people depending on how much of their maximum power they had used.

So, she rested. She dreamt. She tossed and turned. It was time for her to keep sleeping, keep dreaming, keep resting, keep–

SLAM!

Fubuki jolted awake with a firm gasp, almost hopping out of her bed. Her heart rate elevated, and she could feel blood rushing to her head.

What was that?! She glanced around, eyes scanning rapidly for any sign of a threat. She was already using her powers to retrieve her hero outfit, prepared to change into uniform to get to work. A monster ambush?!

She took deep breaths, scanning around for any sign of a threat.

Nothing. No monsters. No imminent threat. Her powers weren't even warning her of any dangerous presences nearby. And as she looked outside the window, there weren't any earthquakes or property damage.

…Nothing? Fubuki wondered, confused. I wasn't having a nightmare… She looked at her hands, which were slightly trembling.

She gulped, and prepared to go back to sleep–

SLAM! SLAM! SLAM!

Fubuki gasped, loudly this time, and clutched at her core. Her legs felt weak, and she had to lean against the wall to make sure she didn't fall. She lightly groaned, her breath getting heavier.

"The…hell…?" Fubuki whispered out, utterly taken off guard. What was going on with her? She had no idea what was even attacking her. There weren't any hostile presences nearby, and no external threat had presented itself, at least it seemed. What could be doing–

SLAM! SLAM! SLAM!

"F-Fuck~!" Fubuki squeaked out, voice higher as the sudden sensations became much more forceful. Yet, after a moment, she realized what had just happened.

Fubuki came back to her senses, glancing around to see what was messing with all of her nerves like this. What had even tried to do something like this?! Her body had natural defenses around it precisely because of her psychic powers, and she knew that anything hostile towards her would have some sort of killing intent that would make itself clear to her.

Then, out of nowhere, a voice quietly popped up in her head.

"P-Please…" the voice whispered, and Fubuki's eyes widened.

Big Sis?! Fubuki realized, and instantly, fear flooded her heart. She had never, in her entire life, heard her older sister sound that vulnerable. That…that…that weak. If she hadn't known it so clearly, Fubuki would've sworn that it wasn't her sister whose voice just came up in her head.

She heard Tatsumaki's voice once more, "S-So…so r-rough!"

Fubuki gulped, …rough? Something existed that could actually still treat her sister roughly? She could've sworn that, after the entire Monster Association attack and having to deal with Garou, there wouldn't be anything anytime soon that could corner the Tornado of Terror.

And yet, that's exactly what it sounded like.

…Wait…

Why exactly could Fubuki hear her sister's voice?

She wasn't sure if her shock could grow any more, but it seemingly kept going beyond its normal limits.

The only way this could happen…Fubuki rationalized. Is if Big Sis is being overwhelmed… She vividly remembered one instance from their childhood, where Tatsumaki had only recently come back from being taken away.

It was dangerous. Her emotions had overcome her, and she was unable to fully control her powers. Fubuki herself didn't want to remember it, because all she could remember was hearing Tatsumaki's thoughts roaring in her head as she destroyed the land around her.

Fubuki gulped.

What, of all things, could be overwhelming her now…?

Fubuki felt even more fearful.

And why is nothing on the news about it…? At this point in time, the only way that something could overwhelm Tatsumaki of all people would be a city-wide disaster, which would instantly appear as a notification for her on the Hero Network. A chill ran down Fubuki's back.

Or is it that it's something the Hero Association doesn't know about yet…? That was…a possibility. What if it was something happening in space, where the Hero Association had no idea what was going on?!

Fubuki was horrified; how the hell was she going to do something if it was overwhelming Tatsumaki of all–

SLAM! SLAM! SLAM!

"O-Oh, s-shit~!" Tatsumaki's voice blasted in Fubuki's head, even louder than before, and while the sensation registered in Fubuki's body, the concern and life-threatening fear took priority, her body unable to even react.

What should I do?! What do I do?! What CAN I do?! Fubuki almost panicked, before taking a deep breath. She had one choice: Act like a professional. Keep calm. Contact Saitama, maybe, and then go to the scene herself. I can't tell the Blizzard Group. If they come with me, they might be in danger, too. I'd be the only one who could escape. She chose to go it alone.

She sent a quick text to Saitama, stating, "If you see anything dangerous, tell the Hero Association. Something might be happening to Big Sis." She wasn't going to be able to tell him much else; this was urgent. She had to get to the scene of whatever was going on as soon as possible.

For a moment, Fubuki took a short breath. This might be a life-defining moment for her. She might not come back as the same person, if at all.

So, she felt her sister's aura. Pulsing violently. She could feel the writhing, and gulped. For her sister to be twitching in that manner, she must have been in great pain.

Fubuki knew that what she was getting into might be her very last mission. Yet, as a hero, she could not ignore it.

She started flying in the direction of her sister's aura.

SLAM! SLAM! SLAM! SLAM! SLAM!

The pangs became stronger and more powerful the closer that Fubuki moved, and for a few moments, Fubuki became overwhelmed. She yelped, losing control of her powers momentarily. While Fubuki had been flying, at most, she was able to glide down to a roof and land safely. She needed to adapt for a few moments, get a moment of respite.

She grit her teeth, however. No! I need to keep going! Who knows what's going on?!

She stood up again, ready to fly again–

SLAMSLAMSLAMSLAMSLAM!

"F-Fuck!" Fubuki squeaked out once more, the pangs coming in another wave, this time even faster with more intensity. She fell back onto her ass this time, unable to stabilize herself. "W-What's going on?!" Her vision was getting blurry, and her heart was pounding so hard she could basically hear it over almost everything else. With the quiet of the nighttime, it only seemed even louder.

The pangs went quiet for just a moment. And Fubuki's heart dropped. No sign of destruction ahead of her. Was the threat really that cruel? What if it was already over? What if…

No. Fubuki refused to accept it. There was no way that something had single handedly defeated her sister without even destroying a city's worth of land. No matter how rude Tatsumaki may have been to her, Fubuki still couldn't fathom the thought of her sister losing, even after everything that had happened.

Keep going, Fubuki encouraged herself. She wasn't able to stand anymore, but she had to keep going. Her powers still worked, and her vision was slowly returning. She lifted her own body with her psychic powers, and continued flying towards her sister's psychic aura, which was getting stronger at the second.

City Z…? Fubuki noticed, seeing the bright neon sign which differentiated the cities. Fubuki deduced it quickly. There must be some hidden remaining remnant of the Monster Association here…

She kept flying closer to Tatsumaki's aura, which at this point was roaring in terms of psychic energy. She could see a small area illuminated by her energy, even if nothing was moving. What was going on…? Were her powers somehow being drained…? The only orga–

SLAMSLAMSLAMSLAMSLAMSLAMSLAM!

"O-Oh, god!" Fubuki heard Tatsumaki cry out, but she wasn't able to focus on that for long, her own self being heavily affected.

"S-Shit!" Fubuki cursed, losing control of her powers once again, barely able to maintain any semblance of power as she started crashing down to the ground. If it weren't for her powers, she would have definitely incurred some severe injury as she landed on her side, some dust being kicked up as a result.

She was only able to help herself stand up at this point, but she could barely see. Everything around her was getting blurry, and because she was in the sort of field of power that Tatsumaki had inadvertently created, Fubuki was barely able to exert any of her own and actually control it. It was just…overwhelming.

Fubuki stumbled closer to the aura, and she could tell that it was elevated. She must've been within this multi-storied building. Fubuki whipped her head around, looking for the stairs, and was barely able to find them.

She stumbled her way up there, her legs shaking as she stepped up, but she had to keep going. If anything, she needed to know what the threat looked like. She could organize something, report it to the Hero Association, get them to gather something that could possibly face against what defeated Tatsumaki. Hell, she would probably end up asking Saitama since he's probably the only thing available that could beat that!

So she kept walking. She went up the stairs, stumbled her ways forward, fought–

SLAMSLAMSLAMSLAMSLAMSLAMSLAMSLAMSLAMSLAM!

"I-I'm~ Ngh~!" Tatsumaki's voice was breaking apart, and she wasn't even able to get more than a word out at a time. That desperation and vulnerability was the only thing spurring Fubuki on; she wasn't going to let Tatsumaki's valiant effort all be for naught. Her body moved, even if electricity surged through it as if actual lightning had struck her.

Fubuki came to the only remaining obstacle between her and taking the first step to saving her sister's legacy: a door.

She slammed the door open, her vision finally clearing up, and–

SLAMSLAMSLAMSLAMSLAM…SLAM!

Tatsumaki whined out, "I-I'm~ O-O-Oh! Y–Yes~! I-I l-love you~!" Her legs twitched, clutching around a human form as her hands grasped around violently at her assailant's back.

Somewhere deep inside her, Fubuki died inside.

Because at 1:17 in the morning.

On this day.

Fubuki had to witness her own older sister.

Getting fucking railed by Saitama.

Tatsumaki, only now reopening her eyes, gasped, glaring at her sister, yet her legs never unrelenting and hands still grasping at Saitama's back.

"G-Get…" She growled out, trying to ignore the sensation of Saitama making her his. "OUT!"

She closed the door. Slammed it closed.

She took a singular breath, and just when she was going to leave–

SLAM!

She ignored the feeling of…something filling in her core.

Extra: An Interaction

Saitama: Hey. You two.

Fubuki and Tatsumaki, evidently unable to look at each other: …Yes?

Saitama: What happened between you two?

After 5 minutes…

Sitch: I understand your frustration, but next time, please don't destroy 5 city blocks throwing debris at another hero.

Tatsumaki: No promises.

Saitama: Tats…*another building flung into his face* Okay.
