Start by Eating Jake Jake no Mi

The moment Masa devoured Rob Lucci, Masa gained everything about Rob Lucci, whether it was talents, knowledge, or even the ability of the Neko Neko no Mi Model: Leopard. 

Then, as expected, it was so easy for him to achieve the "awakening" state of this Devil Fruit. 

At that moment, his body became more muscular, yet he maintained a balanced figure instead of appearing bloated and ugly. Instead, due to his special ability, his appearance had always been good, but compared to the change in his body, he also gained traits of a leopard instead of appearing like a fierce and ugly monster like Rob Lucci in the original story. 

If one had to say, his appearance was like that of a demi-human from a fantasy story, which made him strangely bewitching, especially the fur parts. 

'But this is an awakening, huh?' 

Masa knew that a Zoan type of Devil Fruit allowed the user to have three forms: a standard form, a beast form, and a human beast form. 

However, when he achieved an awakening, besides having leopard traits, there was a dark flame that formed a "mane" down his back and arms, and a stream of floating fire wrapped around his shoulders.

This was cool, he thought. 

'But this human beast form...' 

Masa felt like he should make this form better as it felt weird to have animal ears on the top of his head. Still, it was fortunate that there were four Masas, so their charms were four times stronger and somehow automatically fixed his appearance in this form better. 

As he tried his new Devil Fruit, naturally, he didn't forget about the rest of the members of the CP9, who he had blasted away previously to start his experiment. He knew that this member had eaten a Devil Fruit, especially when he saw this man's figure had transformed into a human wolf, clearly showing evidence that this man had eaten Inu Inu no Mi, Model: Wolf. 

As Masa had mentioned before, he wanted to try to determine whether it was possible for the Devil Fruit to reincarnate within his body when he killed its user. 

If it was any other Devil Fruit, he might hesitate, but if it was this Devil Fruit, even if he failed, it didn't matter, he thought, so after he had put all types of fruits inside his body previously, he directly put this guy into his body and waited for a while before—

"Success, huh?" 

Releasing the body of the man as he didn't think the man's talent was worthy to be devoured, Masa looked at the Devil Fruit in his hand. 

"Inu Inu no Mi, Model: Wolf." 

Masa murmured for a while, thinking that this Devil Fruit also had a lot of possibilities if it was brought to the world of DxD. "If it's brought to the DxD, it might even become Fenrir." 

Nevertheless, there was no doubt that Masa knew that he had to do further research on biology, medicines, and everything related, especially when all the spots for his Devil Fruits were full. 

"Jake Jake no Mi, Ton Ton no Mi, Pika Pika no Mi, and Neko Neko no Mi, Model: Leopard." 

Those were the four Devil Fruits that he had eaten, and Masa thought half of them were weird, but then again, there was a certain possibility of evolving the Neko Neko no Mi, Model: Leopard into a Model: Nemean Lion. 

"However, what about Jake Jake no Mi?" 

The Jake Jake no Mi was good, and it had many uses. Rather, this was his first ability and the one that helped him in many things. 

Yet, as expected, when he thought of a certain Devil Fruit, he couldn't help but sigh helplessly. 

"Fuku Fuku no Mi..." 

As Yuki Yuki no Mi would always be defeated by the Hie Hie no Mi, Masa knew that it was impossible for Jake Jake no Mi to defeat the Fuku Fuku no Mi. 

Yes, Masa might have developed the Jake Jake no Mi into something that one couldn't imagine, yet... yet... the word "jacket" would always limit its possibilities. 

On the other hand, Fuku Fuku no Mi meant that it could control an entire clothing! 

T-shirts, pants, jackets, panties, and many others! 

Even armor! 

Somehow, Masa thought of the Balance Breaker armor from the world of DxD and used the Fuku Fuku no Mi; it would be possible to mimic them! 

Any type of clothes, whether it was advanced technology or even fantasy fiction, were possible to create! 

'However, since I can devour, and as my Zoan can evolve...' 

For some reason, Masa felt his soul tremble as if he could hear the voice of the Jake Jake no Mi. 

'You want it too, huh?' 

As expected, this Devil Fruit would become a Hito Hito no Mi, Model: Masa form, in the future. 

Nevertheless, when Masa tried to do an experiment, the other members of the CP9 woke up, and when they saw the mess and the corpses of the two most powerful of their group, they quickly shivered with fear, and their only thought was to run away! 

Run! 

They weren't sure where Masa was, but for one thing, they knew that they had to run as soon as possible! 

"Oh, are you going to run away as soon as you wake up? Shouldn't you greet me first?" 

"Eh?" 

All of them were confused, but suddenly, they saw Masa appear before them, emerging from the light, which made their eyes widen. 

"This Devil Fruit...?!" 

"Have you been kicked by the speed of light?" 

Blueno's head was blasted, and he was killed instantly. 

'It's over...' 

No one thought that they could survive this disaster, and all of them knew that they would die! 

Pika Pika no Mi! 

While Masa hadn't confirmed anything, they were sure that Masa had eaten the Devil Fruit of Kizaru, the admiral of the Marines! 

"Ah, I—" 

Burst! 

A beam of light passed through the head of Fukuro, a man with a zipper-like mouth. 

"....." 

Kalifa fell in silence, watching another of her comrades fall powerlessly, unable to do anything. 

"I... I..." 

She was completely wounded, and the fear had her body unable to lift a single power as they were completely frozen due to fear. 

Among Rokushiki, the ultimate martial art of the World Government, there was a technique known as Soru (Shave), which allowed her to move at superhuman speed and Beppo to fly, which should support her to escape. 

Yet, in front of the speed of light, could she even do anything? 

Nothing could be done; any methods to fight were meaningless. 

In front of overwhelming strength, everyone could only succumb. 

So—

"Please don't kill me. I will do anything." 

"Weren't you the one who tried to kill me first?" 

"I..." 

Kalifa felt an intense regret, knowing that her life was about to end. As an agent, she should prepare to lose her life, but if possible, who wanted to die? 

But then... she realized something. 

Why didn't Masa kill her directly like others? 

Why did Masa let her talk?

"Can you stand up?" 

As Masa stretched his hand, Kalifa stared at him for a while, then reached him softly, as she said weakly, which enhanced her charm and made any man wish to protect her, "I-I can't stand up..." 

"It can't be helped, let me heal you." 

Kalifa blushed, but then, well, it was okay, she thought, especially when she didn't hate this at all. 

---

Unlike Perona, who had fallen entirely into her sleep, Carina suddenly opened her eyes and saw Masa enter the bed, then stared at him lazily as she yawned. "Let's sleep." 

"Okay." 

As expected, his woman knew him well, but it didn't matter since Masa just helped Carina, so she wasn't so tired. 

Hugging her in his arms, Carina also moved closer snugly as they had a sweet dream and slept well that night.
