Later that night, as everyone was asleep, Kairo was on watch duty. Since he had slept the whole day, he remained awake at night. He also used that time to train. While he wasn't training his physical body, he was focusing on his Haki circulation. He was training his Haki—some might say this was chakra control, which in One Piece terms would mean he lost less Haki per attack. Which was kind of busted, if you really think about it.
Robin, who had just finished a book about the story of Sky Island—of course, it was mostly myth and hearsay, but hey, they were on the road for it, so why not just read some books about it?
She closed the book and walked toward Kairo before opening her mouth and saying,
"You don't sleep much, do you?"
"I am trained to only need four hours of sleep," he said calmly. She raised a brow at that.
"Hm, you slept for eight hours today. So, your training was either not sufficient, or... you are avoiding me, dear~"
Cold sweat poured down Kairo's back. Oh, she knew.
"I had my reasons," he replied calmly.
"I am sure you did. Transforming into another person—is this how you managed to escape the World Government?"
"It's a simple trick, really," Kairo said nonchalantly.
She decided to see what she could probe from him.
"There was a Buster Call, four... maybe six years ago. From what I heard, there was a secret society of Lunarians living somewhere in the Grand Line. They had what seemed to be a society there, a hidden village."
Kairo raised an eyebrow. He had no idea about that.
Some flashes of memory surged in his mind: burning buildings, magma, explosions going everywhere, something about his parents telling him to live. He blinked multiple times. Those hallucinations were getting very hard to ignore.
"I have no memory of such an event. My last memory is of me waking up in Little Garden with a broken boat nearby. I remember nothing else. I can't even remember my own parents' faces. All I know is that they were both Lunarian, and those skills I possess—they did possess them too."
Robin raised an eyebrow. So he was in fact in Little Garden. That was why the World Government had no clue he was alive. Any adventurer who went to Little Garden would have gotten killed by the giants living there—or the bugs. They had a nasty venom that could kill someone in literally days, not weeks. It was that scarily effective.
And since he was a Lunarian, she guessed he could survive that long. And she remembered that he had, in fact, one-shotted Crocodile. Yes, she was awake to see it. Even if Crocodile was weak at that moment, he still got his shit rocked by Kairo, and from the look of it—
While he couldn't read the Poneglyphs, he seemed to be able to hear what they were trying to say, though not as well as her. A way to put it: while she would be fluent in the language, he would be able to guess the meaning behind the words without actually knowing it.
It was like coding. He was like that one guy who knew nothing about coding and could somehow code a game well—but if you told him to explain what everything in his code did, his brain would short circuit because he would be unable to tell you even a single word. Yes, it was that bad.
She knew he was worth 125 million berries right now, but she bet it would be higher later. And while yes, Crocodile's civil war plan didn't happen, he had kind of stopped it.
Kairo knew that Chopper wasn't done with his pills yet. He would wait; they took time, and Chopper was like the best doctor alive.
He would train Usopp later, but for now, he was on guard duty.
She yawned.
"Goodnight, ninja," she said, going into the room to fall asleep somewhere near Nami.
He nodded his head. He was there for guarding duty. The moon looked wonderful. It was full and perfect. He felt a strange longing as he looked at the moon, as if that was where he was meant to be.
"Sky Island," he muttered to himself. He would go there. He was sure there was something in Sky Island that would jog his memory. For now, he was safe. It wasn't like he was going to run into a guy who would probably be the final boss of the story in the next arc. He wasn't that unlucky.
Oh well. He focused on the sound of the waves, his hands going through multiple hand seals. If he wanted to be a ninja, he had to get good at making those seals.
Opening his mouth, he created a beautiful water dragon. It was pretty. He smiled as he watched it float around.
Another set of hand seals later, and he had a dragon made out of fire, flying alongside the boat. It looked beautiful. He was simply making constructs with different elements, experimenting with his power. Draining his Haki to 50%, then doing some physical exercise while waiting for it to recover—and then rinse and repeat.
It was truly the grind. He was sure that going like this, his Haki control would get better. He even tried making Conqueror's coating constructs, but it was hard. He tried making a clone out of Conqueror's Haki, but it was unstable, and that shit worked more like a bomb than anything else.
A/N Would you rather get Kirk from Kenjaku brain.
Or
Spend one day with Mayuri.
