Chapter 19: Nojiko, Your Subject is Water Breathing

Explorer, Gym.

After witnessing the power of my Shadow Zenitsu, Nami enthusiastically began a new phase of training. Despite continuously sweating, it didn't affect Nami's exercise routine.

Meanwhile, in a corner of the gym, Rosen and Nojiko sat facing each other.

"Phew..."

Nojiko exhaled, slowly opening her eyes.

"Mr. Rosen, it seems like I successfully completed that breathing technique just now."

Nojiko lightly touched her chest, carefully feeling the rhythm of her breath from earlier.

"Hmm, it looks like you're more suited for 'Water Breathing,' Nojiko."

"In the days to come, you should train according to the methods of 'Water Breathing.'"

Rosen nodded, repeating the breathing method of Water Breathing for Nojiko once again.

Nojiko listened attentively, afraid of missing anything. Even after Rosen finished speaking, she closed her eyes and began to memorize.

"Nojiko seems to have a high adaptability to Water Breathing."

"I wonder what challenges she will encounter in the Swordsmanship Enlightenment Room later."

Watching Nojiko earnestly memorizing, Rosen immersed his mind into the system space, using the remaining "Novice Swordsman Challenge Permission" on Nojiko.

[Host uses 'Novice Swordsman Challenge Permission,' Challenger: Nojiko, Opponent: Tanjiro Kamado!]

[Name: Tanjiro Kamado]

[Health: 300]

[Weapon: Nichirin Blade]

[Swordsmanship Level: Iron-Cutting Realm (Novice)]

[Sword Style: Water Breathing, Sun Breathing]

[Special Ability: None]

"Tanjiro Kamado, the young swordsman?!"

"There's also Sun Breathing among the sword styles!"

"If she can defeat him, can Nojiko also use Sun Breathing?"

Rosen closed the system attributes panel, carefully examining Nojiko in front of him.

"What's wrong, Captain Rosen, is there something on my face?"

Nojiko opened her eyes, seeing Rosen staring at her intently, she couldn't help but touch her face.

"Nothing, just thinking about your future challenges in the Swordsmanship Enlightenment Room."

Rosen waved his hand, saying.

"I see. I thought Captain Rosen was interested in Nojiko."

"Actually, I was thinking about whether to match you two."

At this moment, Nami walked over, wiping sweat with a towel.

"What are you talking about, Nami."

"As an older sister, I don't intend to meddle in my little sister's relationships."

Nojiko's mouth curled up, teasing Nami.

"Come on, Nojiko, I've already said that Captain Rosen and I don't have that kind of relationship."

"Is that so? Then why are you so comfortable wearing so little in front of Captain Rosen?"

"Nojiko, you saw it just now, exercising can cause a lot of sweat. Besides, this is just a swimsuit, it doesn't matter, right?"

"But this isn't a swimming pool, is it?"

Nojiko stood up and walked to Nami's side, jokingly.

Hearing this, Rosen glanced at Nami, who was walking over in a cool swimsuit.

"My health points increased by 100. It seems that's the effect of using D-grade nutritional supplements for exercise."

"To upgrade from D to C, it requires a total of 500 health points."

"If nothing unexpected happens, Nojiko and Nami should be able to upgrade from D to C in two days."

With that in mind, Rosen took out five bottles of D-grade nutritional supplements from the system space and pushed them in front of Nojiko and Nami.

"Nojiko, these are D-grade nutritional supplements, the same kind Nami drank just now."

"D-grade nutritional supplements are perfect for you and Nami right now."

"If nothing unexpected happens, after these supplements are consumed, your strength will enter the next level."

"If you also upgrade your level, Nami, you'll be able to start using the Shikai of your Zanpakuto, 'Pierce, Gonryumaru,' right?"

Hearing this, Nami couldn't help but glance at Gonryumaru placed on the counter nearby.

Thinking of the power of Gonryumaru that Rosen had shown her before, Nami felt excited and more determined to train well, in order to defeat Zenitsu in the Swordsmanship Enlightenment Room and obtain the next Swordsmanship Realm.

"Captain Rosen, are you giving us these nutritional supplements because you're planning to leave the Explorer temporarily?"

Seeing Rosen handing her another manual titled 'Water Breathing,' Nojiko keenly sensed something.

"Yes, since we've arrived at a new island, I plan to explore it thoroughly."

Rosen nodded.

"Captain Rosen, don't you need to exercise with us?"

"Did you feel shy seeing me in a swimsuit?"

Nami walked up to Rosen and nudged him with her elbow, with a playful smile on her face.

"If you want to make me feel shy, you'll need another two years of development, Nami."

Rosen lowered his head and glanced at Nami's somewhat flat chest, shaking his head involuntarily.

Compared to two years later, Nami still had a lot of room to grow.

As for exercising in the gym! Rosen didn't have B-grade nutritional supplements on hand right now, so exercising in the gym wouldn't have much effect.

Rather than wasting two days in the gym, he preferred to go outside for a walk.

Incidentally, he could also avoid the Arlong Pirate Group from doing anything harmful to Cocoyashi Village during this time.

Although he intended for Nojiko and Nami to handle the Arlong Pirate Group's affairs themselves.

But if the Arlong Pirate Group did something bad to their hometown during Nojiko and Nami's training period, Rosen would feel uncomfortable.

"What are you talking about? I'm not that young anymore."

Hearing Rosen's words, Nami pouted immediately.

"Okay, stop teasing."

Rosen patted Nami's shoulder.

Once again, he took out a card from his personal system space and handed it to Nami.

"Nami, this is the permission card to start a fight with Zenitsu in the Sword Enlightenment Room."

"You're my partner, and with the mark on the back of your hand, you can activate the challenge permission."

"I'm giving you this card. When you feel confident, go challenge him."

"Don't worry about dying from defeat."

"Even if you die in a fight in the Sword Enlightenment Room, you'll be resurrected."

"Of course, if you fail, you may lose the chance to obtain Zenitsu's swordsmanship knowledge."

Upon hearing this, Nami didn't hesitate, solemnly taking the card from Rosen's hand.

She understood that Rosen wanted her to make her own choices and judgments.

Although there was some pressure, she didn't want to back down.

"I understand, Captain Rosen."

Nami nodded heavily.

"Okay, during this time, I may be out often. You two should train well here."

"Nojiko, there are some ordinary swords in the warehouse that you can use to practice Water Breathing sword techniques."

"Don't worry about my safety. On this island, no one has the power to harm me."

Rosen patted Nojiko's shoulder and gave them some advice.

Then he turned around and left the gym.

He planned to take advantage of Nojiko and Nami's training time to check on the situation at Arlong Park.

"Alright, let's start training."

Nami stretched lazily. "Nojiko, do you want me to introduce the equipment here to you?"
