Back in Solaris, Nami and Robin are in a museum with Elly and her parents to have a look at some artifacts. It's not just any museum; it's the Solarian Museum of National History. For the former, she is annoyed of how the guard is speaking in some strange language while walking with the group.
"All the museums in all the world, and I got stuck to one where the guard is speaking Solarian!"
"I thought you said you've been here before," Robin commented.
"Well, Robin, the truth is, I've been to Solaris as a kid before, but I barely learned their language."
"Look at the bright side, Nami. You got me and my parents to help you translate of what they're going to say," Elly said while putting her hand to her friend's shoulder.
"I also know about their language because I studied this country before," Robin added.
She stopped walking when she comes across a painting of Sophia, the 'Holy Mother'. Upon looking at it, she becomes suspicious due to a connection with Elly as she faces her.
No doubt about it. Elly is the reincarnation of Sophia. Then again, one of the rules regarding reincarnation is that the person has no memories of his/her previous life, she thought.
"I see you've been looking at this painting," Erich approached her. "Nico Robin, isn't it? The archeologist of the Straw Hat Pirates? I'd like to speak with you privately."
"Sure, Mr. Van Houten," Robin agreed.
The two walked to a hallway where the people could not see their conversation.
"Robin, Medena and I have been wondering about our daughter. She's quite different from other Solarians, including us, because she has red hair instead of blonde, and her eyes are blue-violet instead of blue. Come to think of it, there are times she even think she's just our stepchild and that her mother is a redhead nanny," Erich explained.
"Here's a good explanation I can come up with, Mr. Van Houten. It's plausible because red hair works genetically allows for blonds to be recessive for it, and that she is the reincarnation of the person by that painting," the archeologist explained.
"That's what I'm thinking as well."
"Me too," Nami arrived to them.
"Nami, you heard this?" Erich demanded.
"I've been here before when Elly and I were eight years old, and what Robin said is exactly what I'm thinking as well when I saw that painting. Then again, it's mostly common for people who were reincarnated not to have memories of their previous lives."
"Then, you two mustn't tell Elly about this until she regained her memories," the blond man urged.
"Sure thing, sir," Nami agreed.
"Agreed," Robin added.
The three went back to the group when the guard stopped walking as he showed the exhibit of some golden staff that has a red diamond, and Nami looked at her to know what is he saying, so she translates on the dialogue.
"He said, 'This is the staff of Adolf. It is said to be the most powerful staff found in Earth, and it possesses unlimited power. The diamond is rare because it is made from a material from the planet known as Lilart. This staff happens to possess powers like energy zapping, levitation, telekinesis, and invulnerability.'"
"This is why I'm going to steal it!" a sinister voice said, and as the people looked on who said it, it's Arlong and the rest of his Fishman Pirates. Luckily, Hatchan is not part of that crew anymore.
"Not him again!" Nami is in dismayed as she noticed her archenemy has returned, but she gives out a grin. "On the bright side, this could relief my boredom from hearing that Solarian language."
She appears to strike one of them with her Perfect Clima-Tact.
"Arlong..." she muttered.
"Ah, Nami, good to see you," the evil Fishman said with an evil grin. "I never I'd see you again in this place."
"So, how did you get out of prison?"
"Simple. I had my backup Fishman crew break me out, and now that I'm back, it's time I take back on the time I lost to you and your friends."
Arlong attempted to stab Nami with his nose, which she dodges that and jumps out of the way. She proceeds to dodge this attack four times.
"Hey, leave my friend alone!" Elly runs up to Arlong and sends a somersault kick to his face. She turns to the redheaded pirate. "Nami, are you okay?"
"Yeah, I'm okay," Nami replied back.
"Ah, Elhaym, I never forgot about you," Arlong smirked after recovering from the hit. "Well, think you two can fight this off?"
With a snap of his fingers, the two redheads are surrounded with an army of Fishmen.
"Nami... Elly..." Medena looks worried.
"Don't worry about them, Mrs. Van Houten. They can take care of themselves. After all, childhood friends always watch each other's backs. Also, I'll protect you two," Robin assured as she saw one Fishman coming to her from behind, so she puts her arms in an 'x' shape for an attack. "Ocho Fleur: Flip!"
With this, she uses a pair of arms to knock the foe backwards, and another pair of arms just pulls him to the ground. Just then, another pair is making an attack.
"Clutch!"
This power causes her hands to grow out of her opponents back, these hands clasp the targets chin simultaneously pulling the head back and breaking the targets neck.
"Ready, Elly?" Nami asked.
"Ready, Nami," Elly replied back as she pulls out a rod.
The two then fought the Fishman Pirates. Nami makes use of the Swing Arm function of her weapon after yelling Thunder Charge, and hits some of the crew. Elly hits one Fishman with her rod, does a somersault kick, and jumps into the air as she pulls out another rod, and twirls them in circles to hit the others.
That is the first batch.
For the second batch, Nami summoned a dark cloud above the Fishmen.
"Here comes my Thunderbolt Tempo!" she exclaimed as she throws a speck of light to the cloud, and lightning bolts struck them down.
As for Elly, she hits one of them with her rod before doing a prayer that a large amount of electricity appeared on her weapon.
"Now, this is my Anemo Zap!" she exclaimed as she swings it two times, hitting the other Fishmen in the process.
"Very good, you two," Arlong clapped his hands as more Fishmen appeared. "Too bad there's more."
"This is bad!" Elly exclaimed.
"I know! It is too many!" Nami exclaimed as well.
"Perhaps, you need help, Namizou!" a woman's voice stated.
"Huh?"
A large woman with pink hair appeared from out of nowhere and slashed some Fishmen with her two swords.
"Lola!" Nami exclaimed the name of the rescuer.
"Don't forget about me!" another woman said as she swings a sharp jewel from a wire towards the villainous group.
"Vivi!"
"It's good to see you again, Namizou!" Lola said happily.
"Namizou?" Elly looks confused on what she called her childhood friend.
"It's a long story," Nami replied. "Lola, Vivi, this is my best friend from childhood, Elly. Elly, this is Lola and Vivi."
"Nice to meet you two," the Gebler soldier greeted.
"Same here," Lola and Vivi said together.
"What are you two doing here? And how did you get in here?" Nami questioned.
"Well, we found some spare parts on how we made a rocket to launch ourselves here," Vivi replied.
"As for our reason to be here, we saw your fight with this girl, and we're kinda curious about this Solaris thing," Lola added. "To think you have a Gebler soldier as a childhood friend."
"Well, fate tells us to meet with each other," Nami stated sheepishly while rubbing the back of her head.
"Nami! Elly!" Medena runs to the two redheads with her husband and Robin following up. "Are you two okay?"
"Yes, we're okay, Mother," her daughter replied back.
Both Erich and Medena stared at Lola and Vivi.
"Oh, and this is Lola and Vivi. They're friends," Nami explained.
"I see... So you've made friends from place to place, Nami. I'm impressed," Erich stated.
"This isn't over yet, Nami! And you too, Elly!" Arlong stated sinisterly as he got a hold of the staff. "We'll meet again!"
He left the museum with his crew.
"This is quite unexpected," the redhead navigator muttered.
Suddenly, the rest of the Straw Hat Pirates arrive with them ready to fight.
"Alright, where's the trouble?!" Luffy demanded.
"You missed it," Nami replied with an amusing smile.
The rest went outside the museum as he couldn't believe of what just happened.
"You girls took out Arlong's goons?" Luffy asked with surprise.
"Yes, we did," Nami replied.
Suddenly, she stopped walking and Elly takes notice on this.
"Nami, why are you stopping?" the latter asked.
"I've been thinking, Elly. If you can't leave this place because it's your only home, then just leave the military," the former said with her arms crossed.
"Like I said, I'll think about that. For now, I just want to spend some time with an old friend from ten years ago."
"I want the same thing as well."
The two best friends hold each other's hands as they continue to walk on the mansion.
