Start by Eating Jake Jake no Mi

Still, while Masa wanted to say that Maya was the next one, he couldn't help but twitch his lips when he saw Tatsuya return alive once again, but—

"Continue to kill yourselves after you revive yourselves." 

"Yes." 

Masa then watched Tatsuya kill himself once again and then revive once again, and this process continued even if he turned off his hologram to return to his normal appearance. 

Yes, this was normal since Masa had messed up Tatsuya's brain and made him believe he was Miyuki. 

Tatsuya might be powerful, so powerful that it might not be wrong to call him a god in this world, especially when he had no emotions, which allowed him to use all of his magic to kill billions without worry. 

Not only could he destroy everything, but he could recreate anything. 

Yet, even so, such a being had a weakness, and that weakness was his little sister, Miyuki. 

With the limiter placed on Tatsuya's brain and as this limiter had been put within him for so many years, even with his "Regrowth," it was impossible for him to erase it, so as long as Masa became Miyuki, Tatsuya could do nothing. 

However—

'How do I kill him?' 

Masa was at his wits' end since he really wasn't sure how to end Tatsuya's life. Even with him appearing as Miyuki, Tatsuya would continue to revive with his "Regrowth." This ability was too... buggy that there was no way to fix this problem. 

If Masa could steal Tatsuya's ability, then he could imagine that Tatsuya would use "Regrowth" to regain his ability.

If Masa had the ability to seal Tatsuya's ability, then he could imagine that Tatsuya would use "Regrowth" to return to the state when Tatsuya was unsealed. 

There was no way to defeat Tatsuya the way Masa did! 

Or rather, was it even possible to kill Tatsuya? 

'Oh, wait! What about space?' 

If Masa could throw Tatsuya to outer space, then wasn't it possible for him to kill Tatsuya? 

After all, even if Tatsuya was amazing, his body was just a normal human, and being sent to outer space would definitely kill him, right? 

"Hm...." 

Could it? 

Somehow, Masa could imagine that Tatsuya would use "Regrowth" so many times to keep himself alive, then all of a sudden would use his "Elemental Sight" from outer space, then shoot a "Material Burst."

If it was Masa, then it should be fine since he had a way to protect himself from the aim of the "Elemental Sight," but what about his family? 

Being shot by the Material Burst, a magic comparable to a nuclear nuke, would make them as good as gone!

Sighing, Masa thought about Tatsuya's three magics. 

Regrowth, Elemental Sight, and Decomposition. 

Those three abilities were just too much, Masa thought. 

'Then, what about a devour?' 

Hmm... so this was the only way, but somehow, he could imagine it was like a time bomb inside his body to devour Tatsuya. 

Even if Tatsuya's soul was destroyed, the "Regrowth" might once again be able to help Tatsuya. 

The only way for Masa to end Tatsuya was just to wait for Tatsuya to feel exhausted from killing himself, which would take a long time to handle. More importantly, he didn't want to spend a long time in this place, but all of a sudden—

"P-Please stop this... Please stop doing something so cruel to Onii-sama." 

Unexpectedly, Miyuki woke up and bowed her head in such a shameful manner. It clearly wasn't something that a lady should do, yet even so, she was desperate since she knew well that she couldn't defeat Masa. 

The Supreme King Haki had made her give up fighting and watching her older brother revive and then kill himself so many times; what she wished was just to stop this fight as soon as possible, begging him to stop since she knew well that on this battle, the victor was Masa. 

"Then, let him attack my family?" 

"He won't! I won't let him do so!" 

"Yet, the fact that you let him go earlier? You pamper your older brother too much." 

Masa could kill Tatsuya, but he definitely couldn't kill Miyuki since he was afraid that Tatsuya would go on a rampage and destroy this universe. He might be okay even if the universe was destroyed, but to be in the universe without his loved ones, what was the point? 

"I beg you." 

Miyuki groveled deeply and said, "I know that you don't believe in my words, but I will make him stop his foolish thoughts no matter how many times! I will even use his limiter to make him completely obey me! And, I... I... my everything is yours too..." 

Her life had been given by her older brother in Okinawa before, and from that moment, she knew that her life was as good as for her older brother, so if her soul and body could be of great use to her older brother, such as saving him now, then why should she hesitate? 

Thinking about Airi's words, Miyuki knew that Masa was playful, and she thought that her body could be—

"Eat this." 

Masa took out a capsule and then told Miyuki to swallow it. 

Miyuki took a deep breath, then stuck her small pink tongue out, swallowing the capsule into her body. 

Yet, Masa fell silent when her tongue touched his finger, licking it lightly. "...wipe your saliva on my finger." 

"Y-Yes!" 

Miyuki was ashamed and embarrassed, especially when she saw his cold expression, thinking she might have overestimated her beauty. Masa wasn't as playful as Airi said, and he sincerely loved his fiancee. 

Still, as she wiped his finger with her clean handkerchief, Masa explained, "That's a bomb. If I ever notice that your Onii-sama shows an intent to fight me, then your body will explode."

"Yes."

"...you are not afraid?" 

Masa looked at Miyuki, who appeared calm. 

"So, as long as I don't let Onii-sama have an intent to hurt you or your family, then I will be okay, right?" 

Her clear, beautiful eyes stared at Masa, and she didn't seem to be afraid of his words. 

In other words, Masa wished for a peaceful life without being interrupted by her older brother, but unfortunately, her older brother was just too bull-headed. 

Yet, for someone without an emotion except for the love for his little sister and also the ability to destroy this world, what could he be afraid of?

However, if the life of his little sister was under threat, then what would Tatsuya do?" 

"Don't tell your brother about the bomb." 

"Yes." 

"...." 

Masa stared at Miyuki, feeling strange as she was completely obedient toward him, but in the end, he decided not to think too much before completely disappearing from the two by entering the fiber optic cable by using the power of Pika Pika no Mi to travel. 

"..." 

Miyuki hadn't seen how Masa appeared, but with the speed that he showed, she knew that there was no escape for her and her older brother. Yet, it was fine since, as long as they didn't bother him, their life was peaceful. 

Everyone lived on their own, and no one should bother each other. 

This wish of his was simple, yet Tatsuya probably never understood it, which made Miyuki sigh helplessly. 

Still, Masa was trustworthy, and soon, Tatsuya recovered, realizing that his head lay on his little sister's soft thighs. His expression was pale, yet even so, his eyes blazed with a spirit, seemingly unperturbed by the fact that he had committed suicide and been revived so many times. 

"...Miyuki? Where is he?" 

This time, Tatsuya was sure that it was his real little sister, but when her tears fell onto her face, he was stunned in a daze and quickly asked, "What's wrong? Did he do something to you?" 

"Stop targeting him, and let's live on our own, okay? Please don't bother him anymore since I... don't want to lose Onii-sama, after all." 

Feeling the gentle embrace of his little sister, Tatsuya was lost for his words, then let out a long sigh.

Yet, this problem was far from over since the head of the family allowed Tatsuya to attack Masa. 

"So, you have come?"
