"Talk"

'Thought'

[Control]

"You've been keeping secrets from me, hm?"

Back at the office, Makima was looking through the reports of Kobeni Higashiyama's recent mission, more specifically looking at a picture of when she turned into a large tiger creature, which she did look at with interest.

"N-Not on purpose! I-I just found out today I can do that!"

Kobeni was quickly and desperately trying to defend herself while also explaining what had just happened, which made her boss hum in response.

"Hm, you're not the type to lie to me, and I doubt you would keep this kind of secret from me for so long..."

Makima seemed to believe Higashiyama, which made her relax a little, but it wasn't enough to erase her suspicion completely.

"But that still doesn't explain how you transformed into that beast, unless you really did make some kind of deal with some Devil behind our backs?"

When Makima once again accuses her Devil Hunter, she quickly shakes her head again and tries to deny it, though when she did this, the Boss noticed that her collar necklace was shaking around her employee's neck, which made her narrow her eyes a bit.

"Kobeni, touch your necklace."

Makima placed her reports on the desk and now looked at Higashiyama with all of her attention and interest.

"H-Huh? Why?"

Kobeni, still worried, but now also confused, as she didn't understand why her boss was asking this of her.

"Just do it."

Makima narrowed her red-yellow swirly eyes at the Devil Hunter, who flinched in response.

"O-Ok?..."

Not wanting to anger the boss any further, Kobeni nervously reached out for her necklace's collar, pressing the hourglass symbol on it. A bright white flash shone everywhere, blinding everyone for a moment.

"OH MY GOD, WHAT HAPPENED TO ME?!?!?!"

But after the light died down, the boss was able to see the results of the white flash, and that resulted in Kobeni transforming into a large feminine werewolf creature, with the suit and hairpin somehow.

'Not the same creature from the picture.'

Makima glanced down at the picture, when her employee turned into a large tiger girl.

'However, it does have the same symbol, interesting.'

But even with the clear difference, Makima was able to look at Higashiyama, who was currently freaking out from becoming a monster, and saw that both now and in the picture, had the same symbols, locations were different but still the same overall.

'So it was her collar that gave her this Shape-Shifting ability.'

Makima then got up from her desk and decided to walk up to the monstrous werewolf, admiring its form and what had been done to actually change it.

'And it's not done or made by Devil, I would've sense it if that was the case.'

Makima took a closer look at the device, which looked simple but had an intricate design, and it was able to accomplish a lot.

'This is definitely a rare fine indeed~'

Makima couldn't help but now wearing a very interested and eager grin.

"I-I knew this thing would g-give me nothing but trouble!..."

As the Boss took a keen interest in what was happening, Kobeni couldn't help but hide her face behind her claws and started crying, clearly not understanding what was going on and why it had to happen to her.

"Kobeni."

However, before the Devil Hunter could complain further, Makima placed a hand on her shoulder, causing her to look up at her boss.

"[Give It To M-"

Though just as Makima was about to say something to her employee, the device suddenly released a shockwave of white energy and sent her flying back, into a wall.

"M-MAKIMA!!!"

Kobeni was horrified beyond what had just happened, as she rushed towards her boss to check on her and hope that she wasn't injured anywhere.

'It even has a defense against my Control Devil abilities?...'

Makima, who had revealed herself as the Control Devil, could not help but clench her fist tightly in silent rage, surely not happy to not take what was hers. However, instead of being openly upset about it, she decided to think of something else to use Higashiyama to her advantage.

"I-I'm so sorry!"

Though Kobeni continues to beg for forgiveness, her boss, after a moment to recover, stood back up to her feet and walked towards her desk.

"W-Why does this always happen to me..."

Before Kobeni could cry again from shame and embarrassment, her boss, after taking a seat behind her desk again, looked at her with a "gentle" and "calm" smile.

"I wish to promote you, Kobeni."

What Makima said was enough to break the Devil Hunter out of her depression and look at her with wide eyes shock.

"W-What?"

Kobeni felt like she was hearing things, almost not believing what her boss just said.

"No longer are you just another Devil Hunter, but now you've become a Division Leader, specifically a Division Leader that works directly under me."

But the more specific Makima was with her promotion for her employee, the more she was starting to believe.

"B-But Makima, I don't deserve-"

Kobeni quickly tries to reject the offer, thinking she wasn't worthy of such a position.

"Basically you'll become my personal bodyguard and 2nd in Command."

Though Makima seemed to be ignoring her as she continues to explain the shape shifter's new job.

"W-Why? Didn't I just try to hurt-"

But before Kobeni could continue to reject the idea of being promoted, she was suddenly offered something that immediately caught her attention.

"And with this promotion, your payment shall be increased."

As soon as Makima said, "Increase Payment", Higashiyama stopped her rejection and listened closely to her.

"I-Increased?"

The thought alone was enough to make Kobeni wag her werewolf tail, which made her Boss smirks once she saw she had her full focus.

"Mhm, in fact, how about I increase your bonuses as well, does that sound good to you, hm?~"

After knowing what type of, "Language", that the Devil Hunter spoke, Makima tried her best to sweeten the deal even more so for her.

"I HUMBLY ACCEPT THE PROMOTION, MISS MAKIMA!"

Which was just enough to make Kobeni finally accept her new promotion.

"Good, now then, how about you go home early for the day, both to rest and maybe figure out how your abilities work, ok?"

Once the employee was finally on board, Makima decided to be kinder towards her and allowed Higashiyama to go home early, while also subtly giving her hidden hints about how to use her new powers and how they work.

"T-Thank you very much, I promise not to let you down!"

Which once again made Kobeni very grateful and thankful, bowing before Makima with deep respect before quickly leaving the office so that she could go home and relax, though she forgot to change back and ended up terrifying a few of her co-workers, though this didn't bother the Control Devil, who rested her chin on her hands and wore a very satisfied smile.

'Hopefully, this will be enough to keep an eye on her... And make sure she belongs to me, and only me~...'

Weird question, what should the Kobeni color theme be? Should it be normal? Or should Kobeni have her own theme colors with her aliens? I'm thinking black and white with some hints of red, but what do you all think?

(BTW, wanna let you all know, this is technically a four way crossover, it's Chainsaw Man, Ben 10, Jujutsu Kaisen and Generator Rex, though the last two aren't that important at the moment, so you won't see them mention as much, but they exist)

/When To Introduce Kevin\

Before Chainsaw Man Start: Give a chance to introduce some Ben 10 Stuff early.

After Season 1: To those that want to focus on Kobeni a little bit more before adding Kevin and Ben 10 Stuff.

Beginning To Ben 10 Stuff: Focus entirely on Chainsaw Man story, at least until the part after the Darkness Devil and before Makima betrayal before going deep dive into the Ben 10 story.
