One Piece: Getting Stronger by Writing a Diary

Yamato: "Huh?! I can also master advanced Conqueror's Haki in the future? Kaido is actually a good teacher? Wait, but he didn't really teach me much. He always just beat me with his kanabo!"

Doll: "Kaido's daughter also mastering advanced Conqueror's Haki? This man actually taught two disciples who possess Conqueror's Haki."

Smoothie: "Strange, if Kaido trained such powerful disciples, how did he end up losing to a rookie pirate and losing his position as one of the Four Emperors?"

Custard: "Yamato aside, this Luffy has unexpected talent, his future will surely be more than just the Fifth Emperor…"

Ulti: "Then after Kaido-san's defeat, this Luffy will avenge him?"

Black Maria: "No matter what, Luffy is worth keeping an eye on. While searching for Arton, let's see if we can also recruit Luffy into the Beasts Pirates."

Gion looked deeply at Garp in the distance, her eyes filled with extremely complex emotions.

"A man with as much potential as Luffy… and Vice Admiral Garp didn't manage to keep him from being lured into piracy by Red-Haired Shanks."

"If Luffy had stayed with the Marines and received training from their strongest, he should have been able to acquire future sight in Observation Haki, advanced Conqueror's Haki, and even Devil Fruit awakening."

"He would have become a pillar of the Marines in the future!"

"What a shame! I hope Vice Admiral Garp still has any way to make Luffy give up the path of piracy and turn towards becoming a Marine."

Thinking this, Gion couldn't help but let out a long sigh in her heart.

"Definitely, while trying to stop Arton from entering the Grand Line, we should also try to prevent Luffy from going to the Grand Line as well."

"While the Straw Hat Pirates haven't done anything too outrageous yet, it is necessary to nip their pirate path in the bud."

At this moment, Gion's gaze was more determined than ever.

Meanwhile...

At the Baratie, the floating restaurant.

"Achoo!"

Luffy rubbed his nose, looking puzzled as he raised his head.

"Luffy, did you catch a cold?" Usopp asked curiously after stuffing food into his mouth.

"I've never had a cold!" Luffy frowned.

"I see, then someone must be thinking about you."

"Someone thinking about me? Who?"

"Maybe Uta?"

"Uta? Is Uta also here at the Baratie?" Luffy exclaimed, a hint of excitement appearing on his face.

"Just kidding!" Usopp laughed.

"What? You dare to trick me!" Luffy shouted angrily at Usopp, immediately starting a food fight at the table with him.

Soon, Zoro and Jango were drawn into the commotion as well.

At this moment, Luffy still didn't know that Uta's ship, the Sylvan, had already arrived near the Baratie.

On the Sylvan.

"Luffy will become that strong in the future…"

"As expected of the man Shanks has his eye on."

"In that case, I need to work even harder so I won't lose to Luffy!"

Uta thought to herself, shifting her attention from her diary to Arton.

"To not fall behind Luffy, I may need to earn more points."

"Mnn… I'll have to find more opportunities to earn points in the future."

As she thought about Luffy's future strength, Uta couldn't help but consider her own progress.

Just then, she noticed new content appearing in her diary.

[All in all, the intermediate Conqueror's Haki reward is still quite good.]

[But compared to this reward, the blank character template challenge ticket is even better.]

[With this, I can further enhance the Emiya Shirou template that hasn't reached its limit yet.]

[Once I fully master Emiya Shirou's power, I should be able to surpass the Four Emperors' level.]

[By then, I should be able to easily overpower a Marine Admiral.]

[Hmm... Before I take down a Marine Admiral, maybe I should start by causing some trouble for Gion.

[Last time, that woman got away, but next time I catch her, I'll make sure she realizes how wrong it was to cross me.]

[I can craft three chapters of enslavement scenarios just for her.]

[Although forcing a woman to do something she doesn't want isn't really enjoyable, if it's for the sake of punishment, forcing a little bit might not be a big deal.]

Gion: "Arton, you sure have some bold thoughts…"

Doll: "I'm starting to feel like Arton is becoming more dangerous."

Belo Betty: "It seems crossing Arton isn't a wise choice."

Galette: "So he prefers willing women? Understood. If we meet, I'll be more proactive, Arton!"

[Anyway, whether to force her or not will have to wait until I encounter Gion again.]

[For now, the priority is to find a strong enough opponent for a satisfying battle.]

[It's a shame really; if Shiki had lasted a bit longer in our last fight, I might have fully mastered the powers of Heroic Spirit Emiya Shirou.]

Ain: "The power Arton used to defeat Shiki was already formidable. If he advances further, I can't imagine how difficult he'll be to deal with."

Tashigi: "A power beyond Unlimited Blade Works and Excalibur? Could it be the power of that red-clad Emiya Shirou we saw before?"

Smoothie: "Huhu~ that's something to look forward to."

Whitey Bay: "If he does, the likelihood of major factions successfully recruiting him will decrease even further… Perhaps I have no choice but to integrate into his crew if I want to stay by his side."

Black Maria: "If Arton reaches the level of a Four Emperor, we might have no option but to join the Flame Blade Pirates."

Galette: "Would Mama allow me to leave the Big Mom Pirates and join the Flame Blade Pirates?"
