AN: yeet yeet im back- exams is hell- kill me- also pls check out the second chap. i made changes-

As soon as Sai turned one year old, Yagi deemed her responsible (pft) and intelligent enough to leave her in the day care.

Sai herself doesn't know why he keeps doing that. 'Maybe he's just really busy at work, whatever his work is.'

She's totally not scared that Yagi seems to be distancing himself from her day by day and that she rarely sees him anymore. Totally not.

She glowered at a particular toddler that came up to her, slightly annoyed that the brat found out about her secret spot; the corner just beside a giant doll house. "Ge' out me swa'hp!" She hissed, as the spawn of satan merely giggled at her (angry) statement.

'Y'know, it would've been better if he just left me alone in our apartment.' Sai thought, sulking as the toddler kept pestering her about some weird toy.

"VROOM!" He exclaimed, waving around some kind of… action figure as Sai desperately tried to keep her calm. "Hero! Gyah!" He cried out a series of words, before standing up (albeit shakily) and toddling around while waving (read: showing off) his toy to other kids.

'Yo, what the fuck?' Sai thought with a bewildered look, just noticing that the kid had exhaust pipes coming out of his calves, kind of like an engine. 'I think this just solidifies my decision into not giving a shit about this world's logic anymore.'

To whoever god that made this bootleg version of the marvel universe, dude, what the hell are you on?

Good lord, she hopes that she won't get any of those freaky mutations. Just looking at one is already enough.

Yagi felt bad for leaving Sai in the day care every single day. He really did.

'Don't worry about her, Yagi…' He reassured himself, jumping from roof to roof in his other form while looking for any kind of trouble. '…She probably already made friends there. Yeah.'

He suddenly stopped at an abandoned building's rooftop, before slowly transforming back into his skinny body. "It was just a year ago, too…" He mumbled, feeling melancholy all of a sudden.

Too much happened just last year.

His friend being left by her scumbag of a boyfriend.

Sai being born.

Sai's mother dying.

It was just… too much for him to handle.

But then… Seeing Sai smile, it just reminded him too much of her. And it made him both overjoyed and upset.

That's probably one of the reasons why he's distancing himself from the baby right now, among other things. He just couldn't bear being seeing a face that's just so familiar yet not.

A bunch of screams suddenly pierced through the air, snapping him out of his depressing thoughts. 'Looks like I'm needed again.' He thought with a grin, slowly transforming back into his other form.

"Do not worry, for I am here!"

"Thank." Sai mumbled quietly, as the engine kid kept her company while she was bored. 'But seriously though, the fuck is up with him and heroes?! He just wouldn't stop talking about them!'

Honestly! It's like there are real live superheroes here! Which obviously is stupid because… come on! Heroes?! Don't make her laugh! As if there's someone who's selfless enough to sacrifice their life for others without anything in return!

She watched as Tenya (or at least that's what she heard when his brother called out to him) waddled towards his older brother happily, sighing deeply as Yagi hadn't picked her up yet.

'Maybe he's forgotten about me.' Sai joked to herself with a wry grin, as she watched children being picked up by their own family. 'Okay, I think he really did forget.' She thought, her grin slowly diminishing.

Great parenting skills, Yagi. Surely with that, Sai would be able to grow up with proper care and attention.

Oh, who was she kidding? Even the workers are looking at her with pity. And she doesn't need pity. If anything, they should be pitied because of their stupid- they- she doesn't need to be pitied, okay?!

Sai sniffled, attempting to hold in her angry tears as she wobbly walked towards the glass fence separating her from the baggage counter thing, pressing her face against it.

'Tsk, whatever. I should've expected that this is just gonna be a repeat of my past life.' She thought, as the door open and a man in an overcoat entered.

She heard him talk to the lady who took in charge of the day care, something about a child or whatever. It's probably just another kid being picked up, seeing as there's still a few left with her at the play pen.

"Hey, Sai." She looked up in shock, hearing the man say her name. "I'll be picking you up today, seeing as Toshinori-san isn't- is too busy to." He smiled, as she narrowed her eyes at him.

"Who're you?" Sai deadpanned, as he blinked at her question. "You're- su'picio'." She said, as he laughed at her ability to butcher the Japanese language (or, well, she thinks he's laughing at that).

He picked her up, as she struggled quite a bit. "I'm a friend of your dad- I mean, Toshinori-san," He explained, as Sai stopped fussing to listen to his excuse to kidnap her. "He asked me for a favor to pick you up from day care." He said, which, honestly raised more questions rather than answered them.

Sai sighed, already tired with everything. 'Ugh, whatever. I'll take his bait. S'not like it even matters anymore, anyway.' She relaxed from his grip, yawning as she snuggled for warmth against his coat.

Naomasa Tsukauchi is pretty sure Sai is a genius, just by looking at her blank yet scrutinizing stare.

He's also sure that she's sulking right now, probably because of Toshinori's distant treatment to her.

Tsukauchi observed her while she was asleep, noticing that she looked a lot like her mother. And when he meant that, he meant that the kid looks like a carbon copy of her. He could now slightly understand why Toshinori looked so melancholy whenever Tsukauchi brought Sai up as a conversation topic.

…The question Tsukauchi kept asking himself though, is 'Why did Yagi take her in despite the responsibilities he shouldered?'

Although…

Tsukauchi looked back at the now awake child staring at him with curiosity, deducing that maybe, maybe it was because Sai's mother was always there for Yagi. Maybe he was just returning the favor.

Not only that, but Tsukauchi didn't overlook the fact that she and Yagi used to have some kind of relationship. Maybe it was because of that?

Well, whatever Toshinori's reason is, Tsukauchi trusts the number one hero's judgement.

He knows where Sai and Yagi live, so that answers some questions. Still she couldn't help but still be suspicious of him. Who knows, maybe he's actually a stalker?

Oh look, it's Yagi sulking on the couch. Sai wondered what made him so depressed like that.

She tried to ignore the fact that Yagi is looking at anywhere but her because w-why would he do that? Like, it's not like she's the cause of his state right now, right?

For fucks sake, why are people so terrible when it comes to conveying emotions? It's like watching weird-ass pictures on the internet without any context; you literally have no idea what the fuck is going on.

It just- it pisses her off as much as it amuses her, y'know!

"Hnnnh." Sai grumbled, trying to get out of the overcoat clad man's arms while reaching out to Yagi. "PA!" She accidentally blurted out, as the skinny man looked at her in shock.

He looked startled as Sai kept reaching out to him, until Tsukauchi finally gave the whining child to the man. "You're welcome." He said, nodding to Yagi as the blonde nodded back to him, with Sai to watch the exchange in Yagi's arms.

'Ah, so they really are buddies. Good to know that I haven't met a single criminal at my second life yet.' Sai thought sardonically, slightly reminiscing about her… interesting encounters during her past life as she watched Yagi's friend leave the flat.

Why the fuck is Yagi avoiding her gaze though? Seriously, she's getting annoyed by that a lot already. She's had enough of him treating her like she's non-existent!

Sai bit his hand. It was slightly effective too, seeing as she just started teething last month, just before her birthday. Yagi cried out in pain, removing her small canines from his hand, which now sported a tiny red bite mark.

"What'd you do that for?" Yagi asked her, as she pouted and looked away from him. "…Are you angry?" At that question, Sai gave a small whine of agreement.

Yagi blinked. "Oh." He uttered, as Sai waited for his response. "…I'm sorry." He muttered, softly petting her black hair as Sai sighed in content at his gentle touch.

'That's right. Don't ignore me from now on, or else I'll probably do something worse than just biting your hand.' Sai smugly thought, snuggling for warmth against Yagi, as they both passed out together in the couch.

OMAKE - Teething (it's terrible)

"Sai, please stop biting me- ow!"

"...HnnnNH."

"Are you sure you're okay...?"

"...BITE."

"Wait, wha- OW! Stop it!"

"ASDFGHJKL-"

"I feel need to get you to a doctor. A psychiatrist, to be exact."

"..."
