"Is that... the swordsmanship I just performed?"

"Ikki, how did you use my sword skill?"

Gion looked at Ikki in surprise.

Although there were some differences in the 'Shooting Star' Ikki performed, the basics were still the same.

How could Gion not recognize it?

"Didn't you just use it?" Ikki replied.

"So you're saying that because I used it once, you learned it?"

"Yeah! Is that hard to believe?"

Ikki smiled and turned to look at Tashigi, Vivi, and the others who were running toward them from not far away.

"Let's go, Vice Admiral Gion. I'll be staying in Alabasta for a while. I hope you can fully master Moon Breathing during this time."

After saying that, Ikki put Konpira and Zangetsu, which had returned from its Bankai state, at his waist and walked toward Vivi and the others.

"Ikki, you really are a swordsmanship genius. When I first heard you could easily learn Tashigi's swordsmanship, I didn't believe it. But now I completely do," Gion followed Ikki, looking at him with a sigh.

Her sword technique 'Shooting Star' was different from Tashigi's style.

In terms of power, 'Shooting Star' was many levels stronger and naturally more difficult to master.

But Ikki had mastered it just by watching her use it once.

How could this not surprise Gion?

"Captain Ikki, can I ask you something?" Gion asked.

"What else would you like to know, Vice Admiral?"

"It's... about your sword that can transform."

Gion lowered her head and glanced at the Zangetsu at Ikki's waist.

"Your sword... could it be from eating a Devil Fruit?"

"Why do you think that? Couldn't it be that I ate a Devil Fruit myself and that's why the sword changes?"

"That's possible, but you've already shown the ability to create the Gym and the Sword Training Room. I think your Devil Fruit ability must be creating spaces that help you and your friends train. But this sword's ability to transform and create environments for training seems too different."

"So, Vice Admiral Gion thinks my sword ate a Devil Fruit? But dead objects can only eat Zoan-type Devil Fruits, right? My sword doesn't look like it has a Zoan Devil Fruit."

"Maybe you deliberately don't let the sword show its animal form?" Gion laughed.

"Who knows? If that's what you think, there's nothing I can do about it. But since you asked me a question, let me ask you one too."

"Go ahead, Ikki."

"I'd like to ask if you were around 20 years old when your swordsmanship reached the Mountain-Cutting realm?"

"Huh? Why do you ask that? But yes, I did reach that level at that age."

"I thought so..."

Thinking of the "Mountain-Cutting Swordsman Gion Challenge Permission" he'd just obtained, Ikki felt clearer about it now.

Gion glanced at Ikki suspiciously, but before she could ask anything more, the others had already arrived.

"Ikki, are you okay?" Having learned Thunder Breathing, Nami was the fastest to reach them. She threw herself in front of Ikki and frantically checked him for injuries.

"Don't worry, I'm fine. It was just a friendly match," Ikki smiled and took the Sandai Kitetsu from his crewmate's hand.

"Momousagi Vice Admiral, are you alright? Did this man really manage to defeat you?" Hina stepped forward with a deep frown.

"I did lose this time," Gion admitted. "Ikki's sword power and talent are beyond what ordinary people can reach. Perhaps the position of the world's greatest swordsman will change soon. After all, the man in front of me learned my swordsmanship after just one glance."

The corner of Gion's mouth turned up. She was now looking forward to seeing what would happen when Ikki and Hawk-Eye met.

As the world's greatest swordsman, Mihawk had reached the pinnacle of swordsmanship.

But Gion believed that with Ikki's potential, he was definitely qualified to challenge Hawk-Eye for the title of the world's greatest swordsman.

"This guy... is so powerful!" Hina looked at Ikki with a slight frown. "Ikki, Hina has thought about it. Hina agrees to you teaching her Flame Breathing!"

"Oh, have you now?" Ikki raised his eyebrows. "But you're saying it like I was begging you to let me teach you."

"What, you're not happy? You don't want to learn Geppo anymore?"

"Geppo is still something I want to learn. Now that you're ready, I'll make sure to teach you properly."

As Ikki spoke, he took out Sandai Kitetsu from his waist and handed it to Hina.

"What do you mean by this? You're giving Hina your sword?" Hina took Sandai Kitetsu with a confused expression.

"Don't get the wrong idea. I'm just lending it to you temporarily," Ikki laughed. "When your skills improve further, I'll ask for this sword back."

Since he had to teach others anyway, why not let Hina use Sandai Kitetsu, which he couldn't upload to the system yet?

Once she became more familiar with the sword, Ikki could upload Sandai Kitetsu as a reward by challenging her.

Hina knew nothing about swordsmanship now.

As long as she could learn the basics, she'd be considered to have made progress. At that time, Ikki would naturally gain the authority to challenge her.

Off to the side, Tashigi pushed up her glasses.

Looking at Ikki's smile, she felt like he had some ulterior motive, just like when he gave her the Yubashiri in Loguetown.

[Ding! Host uploaded the Supreme Grade Sword 'Konpira'. Congratulations to Host for gaining 4 lottery chances.]

'Four chances? As expected, a Supreme Grade Sword can be exchanged for four lottery attempts,' Ikki thought.

'System, let's draw the lottery and see what rewards I'll get this time.'

[The lottery begins... Congratulations to the Host for winning: 'A-level Nutritional Potion' x5, 'Intermediate Armament Haki Awakening Potion', 'Intermediate Observation Haki Awakening Potion', Zanpakutō 'Senbonzakura'.]

'Great, more A-level nutritional potions! This means another crewmate can reach S-level life force. After some training, I should have the strength to challenge the 'Sword Shadow of Gion'.'

Ikki felt happy at the thought that one more of his friends could gain the power to release their Zanpakutō's Bankai.

Ikki took out the Zanpakutō Senbonzakura he had just obtained from the system space.

'As usual, the sword that contains the power of a Zanpakutō was included in the lottery rewards. That's good. When Gion comes to challenge me in the future, I'll have another sword to use.'

Ikki patted Konpira, tucked it into his waist, and then planned to take out the 'Intermediate Observation Haki Awakening Potion' to increase his observation abilities.

He easily opened his personal attributes panel.

'Wait! When did my Observation Haki reach the intermediate level?'

Ikki rubbed his eyes and looked at the attribute panel that only he could see.

[Host: Ikki]

[Age: 25 years old]

[Weapon: Zangetsu]

[Life Force: 30550, level S]

[Swordsmanship Realm: Mountain-Cutting Realm]

[Abilities: Intermediate Armament Haki, Intermediate Observation Haki, Intermediate Conqueror's Haki, Conqueror's Haki Infusion, Transparent World, Innate Demon Slayer Mark]

[Swordsmanship schools: Demon Slayer Breathing Techniques, Zoro's Three-Sword Style, Tashigi's One-Sword Style...]

[Items: E-level nutritional potion x4, D-level nutritional potion x1, Mountain-Cutting Swordsman Gion Challenge Permission x1, Intermediate Armament Haki Awakening Potion, Intermediate Observation Haki Awakening Potion]

'Observation Haki has indeed reached the intermediate level... but when?'

'Was it when I was fighting Gion?'

Ikki recalled his battle with Gion. After using the Transparent World for a while, his ability to observe Gion had suddenly improved greatly.

'Is it because the Transparent World, which is also a sensory ability, drove the growth of my Observation Haki? Or was it simply because of that intense battle?'

Ikki shook his head and set aside the Intermediate Observation Haki Awakening Potion.

'I'll give this to one of my crewmates instead. It can help speed up their progress toward reaching the Mountain-Cutting swordsmanship realm.'

With that thought, Ikki turned around and walked toward Vivi, Nami, and Nojiko, who were watching the demonstration of the 'Gion Sword Shadow' move in the Sword Training Room.

"Ikki!" After the demonstration, Vivi noticed Ikki beside her and immediately nodded politely.

"It's amazing that Ikki only fought Gion once and was able to create a swordsman's shadow of her," Nami said, raising her hand to her chin with some confusion. "But why does this Gion look much younger than the real one?"

"Maybe it's because it's easier for us to challenge a younger version of Gion's swordsman shadow," Nojiko suggested. "After all, this Gion seems weaker than the one who fought Ikki earlier."

'Exactly!' Ikki looked at Nojiko and silently praised her intelligence.

"Still, even this weaker Gion seems like more than we can handle right now," Nami pursed her lips and looked at the fading shadow of Gion with some concern. "Even if we use our Zanpakutō's power, it'll be hard to defeat her."

"That's why you need to train hard, Nami," Ikki took out the 'Intermediate Armament Haki Awakening Potion', 'Intermediate Observation Haki Awakening Potion', and 4 bottles of 'A-level Nutritional Potion' from the system space.

"Nami, you were my first crewmate. Your Zanpakutō Gonryōmaru is also a strong attack-type Zanpakutō. I only have one Sword Shadow of Gion, so I want you, as my first crewmate, to improve your swordsmanship first. As for Nojiko and Vivi, I'll need you to wait a little longer."
