"You're not focused enough. You're putting too much strain on your body…"

"Well, excuse me if I haven't done this before!"

"Hn. Your fault for goading me for my tricks."

It was a peaceful, cool morning at the Briefs residence. It was still cloudy and somewhat dark, considering it was too early in the morning for anyone who doesn't have a job or school to go to.

Since Nachi was naturally a light sleeper, not one to exceed more than 5 hours of rest and still function as someone her age should, she was the one who answered the door to the human with pigtails and blue eyes at 5 in the morning.

Why? Simply put, the little human girl wanted to channel her ki and use it.

Really, Nachi didn't mean for it to come out, considering she usually trained with Videl with her own physical strength lowered immensely, along with a relaxed state of mind. She couldn't fight the girl with the mindset of an enemy.

However, 3 days ago, Videl made the mistake of grabbing her furry belt.

Yes, she was immune to the ridiculous tail-grabbing thing that most Saiyans cowered over if one so much as breathes near their appendage. However, it had caught her so off guard that Nachi accidentally sent a ki-blast to the girl's face with a startled yelp.

Not to mention, her tail nowadays was sensitive for some unknown reason.

But back to why she woke up at 5 in the morning, in nothing but one of her daddy's t shirts and panties, hair and tail unkempt and the most blandest look on her face to answer the door to a chipper pale-skinned human.

Really, she didn't know the day she let Videl into her home would lead the girl to have the audacity to bother her in such early hours, but she didn't have a say in the matter.

Now, here the two were, with Nachi still wearing her father's oversized t shirt, except she had gone to her room and quickly slipped on some spandex shorts.

Videl demanded the girl to teach her how to use energy, as the human had said. She had thought they were some light tricks or show the day Nachi attacked her, but considering the amount of heat and how the damage to her stomach was very much real, she deducted it wasn't all fake.

Nachi told her she had to just feel it within her body.

How else can she describe something she's had since birth?

Videl was sitting on the grass, in their usual spot, with her legs crossed and hands in her laps, cupped for something. She was wearing a cut off shirt that reached her shoulders, some spandex that Nachi let her borrow, and green boots. Her hair was up instead of the pigtails she showed up in, in favor in keeping her hair out of the way should it be necessary.

Nachi sighed and lowered herself on the grass, sitting on her calves and bare feet, then reached for the human's hands, which startled her. "You're thinking too much about it."

Nachi closed her eyes, putting little concentration as her ki raced through her body and focused solely on her hands. As her eyes opened, she directed her gaze on tan hands holding pale ones above her own, slowly seeing a pink colored aura raising to the palms. She heard Videl's gasp, but didn't pay her mind.

The ki slowly built up, creating a sphere in Videl's palms, not too big where it's blinding, but enough to cover both her palms. Slowly, Nachi pulled her hands away, leaving Videl to gape at the ki in her hands.

Nachi slightly smirked, as without realizing it, Videl had dropped her guard and was now holding up the ki in her own hands. The girl watched in awe at her own palms as the colored shifted to blue, the color of her own ki.

"Heh, looks like you managed to do something right," Nachi murmured. Videl cast her a glance, but nonetheless beamed in excitement to the girl.

As the ki dispersed, Videl rose to her feet and pumped her fists. "Alright! I can totally do this! I just need more practice!" Just as she said that, her watched beeped insistently, to which answered with a frown. "Satan here… I see… Okay, on my way!"

Nachi cocked her head in silent question as she rose to her feet as well. "There's a robbery down in Satan City. They're holding hostages." Videl quickly shed the cut off shirt with no care in the world, considering Nachi didn't know the definition of decency. Videl then reached into her bag and pulled on a baggy white t-shirt, attaching her Orange Star pin to the bottom and retied her hair into the pigtails.

"Ah, duty calls," Nachi drawled and she followed the human girl at an easy pace as she ran towards the door.

Videl huffed. "It's been what I've been waiting for! Ever since I turned 18, I've been able to go and actually help the police with these things."

"Sounds dull."

Videl shrugged. "Eh, sometimes." She turned to Nachi as she opened the door. "You'll be at school, right?"

Nachi rolled her eyes. "Where else would I be?"

Videl snorted and waved as she threw her capsule out, the sight of the flying hovercraft popping out of the smoke.

She heard the telltale sign of the whirring blades before Videl bid her farewell.

Nachi sighed, as if the world was balanced on her shoulders. "Humans are so troublesome…"

"And why do you insist on troubling yourself with that one?"

Nachi turned to see her father, with nothing but trainers, a towel around his neck and shorts on. She knew he was ready to go in the gravity room, and based on her appearance, he would probably ask her to go in with him.

She dutifully followed him as he headed to their destination, hands running through her hair. "She's entertaining. I see potential in her."

Vegeta rose a brow as he entered in the code. "Potential in a human? Didn't think you went for the human species."

As she followed him inside, she rolled her eyes. "Not potential for a mate, daddy! I mean, I can see some strength in her. She'd be more useful in battle than the scarface," she grumbled.

Vegeta snorted. "You're just saying that because you don't like the guy. Not that I blame you." He set the gravity to 400x, an easy feat for the two of them.

She went to where the mats were placed, spreading her legs and leaving them in a split on the mat as she stretched her arm to the side. "Not only that, but it gets boring having the same opponents. Gohan's always going on about not wanting to seriously hurt me, the sentimental punk he is."

He grunted, pushing up the bar then lowering it. "I'm surprised Kakabrat hadn't come to pick you up this morning."

She furrowed her brows, now stretching her fingers to her toes of one leg then to the other. "You're right. He's usually here by now. Maybe he slept in."

Vegeta shrugged, placing the bar back in its place. "It's better off I don't see his damn face around here. I hadn't forgotten what he did to you last year."

Nachi stood on her feet, cracking her neck. "What do you mean? What did he do?" She had a quizzical expression.

Vegeta grunted. "Nothing to worry about, brat. Now go. You have school in 30 minutes."

Nachi rolled her eyes, putting her hands on hips and walking off. "You are the last person in this home I thought would be worried about my education."

He smirked. "I told you, it's amusing to see your patience tested with being surrounded by so many humans 5 days a week."

She growled and slapped his shoulder in passing while he cackled. "It's not funny, daddy!"

"Oh, but it is!"

Nachi boredly trudged to the front of the building, her binder in her arms and her bag straps clutched to her shoulders.

Unlike the early morning, the weather turned a bit too hot for her taste, so she opted away from her usual spandex unless she wanted to smell like a boy's locker room for the rest of the day. She chose a pair of pair of frayed black shorts, with a burgundy V-neck tucked into the waist, and beige slip-ons that covered up to the middle of feet. Her tail was still tied at the waist, and her hair was let down since she didn't find time to look for her ribbon to tie it up.

As she reached her locker, searching for her history book as that was her first class, a weight settled next to her closer.

She sniffed, immediately recognizing the cinnamon-scented fragrance.

She sighed. And it had been such a great morning.

"Gooood morning, Miss Briefs!" The voice chirped.

Her eye twitched as she slammed her locker closed, her book tucked in the space between her binder and chest, and turned her annoyed gaze to the man leaning against the lockers who had a suave grin plastered on his face.

"Rivers."

And here, was Orange Star High School's local heartthrob, Sencha Rivers.

With dark brown hair, dark eyes, tan skin and pearly smile, who wouldn't be affected by the man? He constantly switched on the charm whenever females were in the vicinity, making it his personal mission to get at least one date with them.

Really, Nachi thought he would fuck anything that breathed, but she wouldn't dare ask.

And alas, she was amongst the few who were completely unaffected by his lavish words and playboy attitude.

"Aw, come on! Don't be so cruel, my fair maiden!" He took her hand, ignoring the growl from her. "Your constant rejections makes me come back for more!"

Nachi sighed. This was a regular occurrence between the two.

But surprisingly, she was used to his antics and he too, was part of the little group that consisted of Videl and Erasa, and of course, herself.

Sencha had transferred from another district towards the end of her 2nd year of high school. He was a bit shy, not really seeking anyone out but welcomed any attention.

It was Videl who had, oh so nicely, invited him to sit at their table during lunch.

The rest was history.

He constantly bothered the girls in his group, more so Videl and Nachi, since Erasa was currently dating someone. At least that's what she told them.

As Sencha prattled on his "declarations of undying love" for the Saiyaness, with his hand still clung to hers as they walked together towards history, she idly thought she felt someone's chilly gaze glued to the back of her head.

Sencha seemed to have sense it as well as he shivered. "Woo! Is it cold in here or what?" He laughed, wrapping an arm around the smaller girl's shoulder. "I shall be your blanket of warmth, darlin'!"

Did Nachi mention the boy was from a southern district?

She grumbled, pushing his arm off. "Cut it out!"

She briefly wondered how to make the boy beside her scamper off, when a brilliant and devious idea came to mind. An evil smirk crept her lips, prompting her to chuckle darkly.

"Rivers, I just remembered something." She turned to him, a sweet smile that was so uncharacteristic of her.

But of course, he fell for it. "EH?! Are you confessing to me, now?!" The suave grin was back on, but she didn't let in deter her.

"Ah, no… However, between you and me," she looked back and forth in the hallways. Confirming no one was around, she clutched her things and used her free hand to cup his ear, whispering, "I heard Satan has the hots for you, but she's just too shy to admit it. Perhaps… you should lay the charms more on her than me."

She stood back down on her feet, watching the boy's blank face tick for a moment before a full-blown smile broke out.

"You really mean it?!"

Internally, Nachi laughed sadistically. "Now, why would I lie to you about your… conquest of love?" Nachi gritted out, a strained smile and her eye almost twitching.

Sencha didn't seem to hear her, as literal hearts were surrounding the man before he laid a smacking kiss on her forehead. "You are my savior, darlin'! I'm gonna go win my girl now!"

With that, he sped off to their class, leaving her in the dust and a disgusted look on her face as she furiously wiped at her forehead. "Eugh, damn playboy…"

As she continued rubbing at her forehead, a sudden warmth appeared by her side and she glanced up, almost dropping her things. "Gohan?!"

Indeed, it was her best friend, Son Gohan. He was dressed in brown slacks, a white long-sleeved undershirt with a black vest, his Orange Star pin shining proudly on the vest.

"Nachi!" He smiled wide. "Mother finally let me go to public school. She figured if you went here, it was safe enough for me."

Recovering from her surprise, she puffed her cheeks and poked at his firm chest. "You ass! That's why you didn't show up this morning!" She backtracked. "Not that I waited for you to show up…"

Gohan grinned. "Well, it's not coming here that made me delay. There was a robbery on my way and well…"

She rose a brow. "A robbery? The same one that Satan mentioned earlier today…?" She murmured.

"Who?"

She waved him off. "Nothing, nothing. Let's get going. I'm already late as it is." She grumbled as she walked ahead of him, with Gohan following right behind.

She reached the classroom, sliding the door open and immediately, all eyes locked on her form.

"Ah, Miss Briefs," the professor murmured. "So nice of you to join us."

Nachi grunted and made her way to the top, taking her seat next to a lovestruck Sencha, who was seated next to Sharpner. After Sharpner, was Videl, then Erasa. She had a bewildered look on her face as Sencha kept staring at her with loving eyes.

Nachi internally smirked.

"Class!" The professor bellowed out, causing everyone to quiet down. "We have a new student here joining us this year. Please welcome, Son Gohan."

Nachi gazed down at her friend from her top seat, catching gazes with him as he bowed and uttered shyly, "Please take care of me."

He scanned the area for any available seats, when Erasa waved her hand. "Yoohoo! Over here, cutie!"

Gohan blushed at the sudden compliment as he sat next to the blonde. "Thank you."

He was in for a long day.

"Moron, how could you not realize how you played the game wasn't normal? Now you garnered attention!"

Gohan chuckled sheepishly, a hand resting on the back of his head while the other rested on the smaller girl's shoulder. "Sorry, Nach', I wasn't really thinking."

"Yes, I gathered that."

The two had gym class together just minutes ago, with the sport of baseball on their agenda. Nachi tried very little, not wanting to give her strength away, and she thought Gohan would give the same courtesy.

Instead, he jumped 20 feet into the air to catch a ball, and when the big oaf Sharpner pitched him a ball, the ball hit Gohan like nothing.

So yes, that rose some questions and even more suspicion of the foreign boy, but Nachi was quick to defend Gohan with some made up lies of how sports weren't a custom in his household.

That saved him, for now.

She grumbled as she took his hand, dragging to the lunch area. "Where are we going?"

"Getting you some food. I'll do it for you, or else you'd end up eating everything on the menu."

With that, she gathered 8 boxes of katsudon for himself, and 4 for herself. She lied to the lunch lady, as always, that her friends were very hungry people and though the elderly woman always looked like she didn't believe her, she relented.

After gathering their food, Nachi lead Gohan to where her little group would sit, unsurprised to see that they made extra space for Gohan.

Sitting down in her usual spot, with Gohan at her side, she immediately had a finger at her chest, pushing in the center. "The hell, Nachi?! What did you say to Sencha?!" Videl growled, irritated that said boy was still clinging to her arm like some lovesick fool.

Nachi cackled in the inside. Oh, how she wanted to relay her joy on the outside.

But she didn't. "Whatever do you mean?" She asked coyly, batting her lashes at the girl.

"You know exactly what I mean, Briefs!" Videl snapped.

Nachi scoffed. "I said nothing to the boy. He just happened to have an epiphany of some sorts." She smirked.

Sencha sighed dreamily, nuzzling his nose into Videl's shoulders while she attempted to brush him off. "My eyes will forever be locked to you, darlin' Satan~!"

Videl twitched.

Ignoring their antics, Erasa turned towards the two, just as Gohan was taking a sip of his tea. "So, Nachi, this the secret boyfriend you've been hiding?" She asked with a smile.

Gohan choked and started sputtering as Nachi cocked her head in confusion. "I never hid my boy friend. I just chose not to mention him unless asked for." She shrugged.

Erasa sweatdropped. "Eh, not a boy friend, but a boyfriend." She clarified.

"What is the difference?"

Before Erasa could explain, Gohan finally recovered and laughed nervously. "A-Ah, Nachi is just a really good best friend of mine. We've known each other since we were very young."

Nachi nodded. "I hated him the first time we met." She stated bluntly.

Erasa nodded, a bit unsurely, while Gohan laughed again at Nachi's social skills.

Then again, he wasn't much better.

As Videl finally calmed down with Sencha at her side, she asked Gohan, "So, how exactly do you get here from your home? You'd have to be waking up at two in the morning to do that!"

Gohan stuttered horrendously, before Nachi came to the rescue. "He stays at CC during the weekdays. Then he goes home on the weekends. My parents know his," she drawled.

Videl furrowed a brow. "He wasn't there this morning!"

"Yes, well, he likes sleeping in."

Videl hummed in suspicion, but before she can say anything else, the bell rang for classes and both Saiyans threw away their trash.

"We're going now," Nachi murmured, dragging the half-breed by his arm while he yelped and quickly followed.

Erasa aw'd at the sight. "They're such a cute couple~! Too bad Nachi is too dense to realize it," the blonde pouted. She was, after all, a notorious matchmaker.

Videl actually chuckled. "Nachi can't even tell the difference between a guy friend and a boyfriend. Who knows when she'll actually realize her best friend is in love with her and vice versa."

Erasa casted the girl a blank look, seeing as Sencha was literally right next to her, having their own love situation going on. "Yes, she's the only dense one in this group."

The two took the roof, narrowly missing Videl's curious chase as she choked, "What the hell?!"

Both breathed a sigh of relief, with Nachi growing a tick mark and seizing Gohan by his shirt, yanking him down to her nose. "Just what the hell did you do this morning, Golden Warrior?!"

He laughed nervously. "Calm down, Nach', I was just helping the cops with their job…"

"That's why they're cops, mutt! They have their own jobs!" She growled to his face.

Gohan blushed at the proximity. "U-Uhm—"

She sighed and let go of his shirt, pacing back and forth on the roof. "People will recognize you, Gohan. This is what we've been avoiding for years. Hell, I'm not sure how I'm still pulling off my own identity with Satan."

Gohan rubbed the back of his neck. "Maybe… I can get a disguise?"

She whirled around to face him, an affronted look. "A disguise…! You're not actually thinking of doing hero work, are you?!"

He sheepishly looked away, but looked more resolved as he locked eyes with her. "This city is just full of crime. Cops can't solve every problem, and they'll need someone with actual strength and can put fear into a criminal's mind."

Nachi facepalmed. "And what about your studies, hm? And Miss Chichi? And even your little brother! Can you split your time with them and school?"

"Of course I can, Nach'! There's even a time slot in there for you!" He stated, blushing a bit. "And besides, it could be fun… and you can join me—"

"Hell no."

"Nachi," he whined childishly.

She shook her head stubbornly, taking off to the skies and to her home. "No!"

He followed along her side. "Come on!"

"No!"

"But I need a sidekick!"

"Sidekick?" She snarled.

"I-I mean, an equal partner!"

"Hmph!"

Their argument continued that way as they reached CC, with Bulma meeting them at the door. "Welcome home, Nachi. And hey, Gohan!" She called out.

Both greeted her, one more enthusiastically than the other. "Hey, Bulma. Mind if I ask you a favor?"

With that, the two headed towards her lab while Nachi went upstairs towards her room, changing out of her shorts into spandex, and kicking off her shoes to walk around barefoot. She uncurled her tail and sighed blissfully, finally free after being constricted around her waist for hours.

She then headed to where she knew her litt ebrother was, finding Trunks walking out of his own room. He brightened at the sight of her. "Big sister!"

Nachi chuckled and caught him just in time, holding him in her arms and nuzzling into his neck. "Hello, little brother," she murmured as she carried on her walk towards Bulma's lab room.

Big as he is, he couldn't resist being held in her arms. It was a place of comfort for the lavender-haired boy. "I sensed someone come in with you. Who was it?"

"It's just Gohan," she rolled her eyes. "He's having your mother construct an outfit for him for hero work."

"Whoa," Trunks muttered. "That's awesome!"

"Eh, if I know his tastes," she pressed a button and the door opened with a hiss. "I'm not too sure about that…"

She trailed off, just in time to see Gohan… wearing a helmet with antennas, a black full body spandex with a green gi on top, white boots, and to make the outfit complete, a red cape.

"… No."

"Wha—"

"That outfit has got to go!"
