As Benimaru woke up, he still couldn't believe that he was in the One Piece world, something that seemed impossible at first, but now, he was in the One Piece, with one of his favorite characters. While waiting, Benimaru controlled his fire generation, trying to control it in a manner like King in the future, but what surprised him was that the color of his fire was blue, similar to Dabi and Azula, which led him to believe that his fire was much more potent than the normal Lunarians.
'Hehehehe, it seems that I would have to thank Saturn if I met him in the future, possibly by killing him myself, so that he would not be killed by Imu,' Benimaru thought, while controlling the flame he generated, he made it into various form, from various birds, a dragon head, bull and a form similar to him, then he tried compressing it and fired it in the sky, which released an explosion so strong that you would think it was a nuclear bomb, this woke up the residents in the house he was staying, and immediately came out.
"What's that? Are we being attacked?" Wolf asked in a hurry after he came out of the house, following behind him is Law, Bepo, Shachi, and Penguin.
"No, I just tested my ability, you can relax Wolf-san and go back to sleep, but you four, it's time I uphold my part of the bargain, let's start training," Benimaru said, explaining what happened and urging Wolf to go back sleeping, and wanting to start the training.
"What? It's so early in the morning," Penguin complained since he was not used to waking up this early, when the sun isn't even out yet.
"Well, if you want to become strong, you have to sacrifice a little bit of sleep," Benimaru just replied. Law was fine with it as he knew that if he wanted revenge, he just on't want his friends to suffer with him too.
"Ughhh," Shachi said, complaining to Benimaru.
"Well, think of a scenario where Law was fighting someone really strong, so strong that Law was defeated, and his life is in danger, and all three of you were just watching as your captain got killed in front of you," Benimaru said, while both Shachi and Penguin became silent.
"You would be pirates in the future, don't you? That is not a game, you're life would always be on the line, and not every time Law would be there to protect you," Benimaru added, while Law was about to retaliate as he did not want his friends to think about this.
"You're right, Law is our friend, and if we want to help him achieve his dream, we should have the strength to help him, so starting from now on, we would make it our goal to become strong," Penguin and Shachi said, while Bepo just nodded, this gesture affected Law as only Rosinante showed him this kind of kindness and caring, something that embarrass Law.
"Shut up, I didn't say I needed your help," Law said, while blushing, with everyone else laughing as they noticed that Law was red from blushing.
"Anyway, let's start, remember that reason, so that everything you do, and would do, would have bearing, and you would not half-ass it," Benimaru said, which was something that all of them agreed on.
The group then started with a run, where they would climb the mountain and go back down 100 times. Around the tenth lap, Shachi and Penguin was really tired, as they began to slow down while Law and Bepo was still following the pace of Benimaru, who still did not feel any fatigue at all.
"Hey, if you did not finish before noon, I'll make you run 100 times more," Benimaru shouted. Shachi and Penguin willed themselves to run more.
After 30 laps, Penguin and Shachi were running on just pure willpower, while Bepo and Law were beginning to feel the effects of their running. While Benimaru was still not tired, it looked like he was just starting to run. After 50 laps, Shachi and Penguin were not even running anymore, just walking while Bepo and Law were still running, but they were panting and heaving heavily.
Benimaru also noticed this and thought that maybe it was too early for this kind of exercise, but Benimaru thought that the body in One Piece is weird, as they would always recover easily and capable of being stronger than normal people, even Nami, were able to take punches from Gunko, who was a member of God's Knight.
Benimaru finished the 100th lap after 5 hours, which he could have finished earlier, but he was trying to slow down to match the speed of the four, which is almost at a snail pace, where Shachi and Penguin was still in their 75th lap where they are now running once again as they recovered their stamina, Bepo was in his 86th lap, as being a mink gave him the stamina of a polar bear, but he was not used to it, and Law was in hisr 96th lap running purely on will power, they all finished at different time, with both Shachi and Penguin finishing at noon, but Benimaru decided not to punish the two since he can see that they have run out of gas.
"Let's eat first before sparring, I catch and prepare these dishes earlier after I finish running," Benimaru said, urging them to eat as it would help recover their strength, as the food he prepared are Sea King's meat, which the Swallow Island have plenty in its shore, with him giving Wolf his share earlier. When Benimaru placed the food in front of the four, they immediately started eating, not caring about their appearances and anything else, just that they were hungry.
-------
After eating, they just decided to rest for an hour before doing the sparring against Benimaru, which involved the four of them attacking Benimaru with all of their current strength. Law was even allowed to use his Devil Fruit, but Benimaru was holding back, it was so clear as he pulled his punches.
"Let's attack on the right side, Bepo, while Law and Shachi look for another opportunity," Penguin suggested, as it was apparent that they were not winning against Benimaru; they hadn't even managed to land a strike against Benimaru. Law then picked up a stone and threw it towards Benimaru.
While his Room is activated, he then switches his position with the rock while swinging his sword towards Benimaru, which Benimaru dodges by tilting his head, preparing to punch Law, but Law switches with the rock once again.
While this is happening, Bepo and Penguin attack on the right side, with Bepo trying to tackle Benimaru and pouncing on Benimaru, who stops Bepo by kicking him away from him and using his other hand to block Penguin. Benimaru did all of this in one movement, as Shachi just stood there, as he was not able to find the opportunity to attack. This fight continued for about 3 hours before Benimaru stopped the sparring as he wanted to help Wolf with the submarine more, and also he wanted Law to rest before he began teaching medicine.
"Let's end today's training. Overall, you all did terribly, but still, you survived your brutal first day. I will guarantee that you will be stronger in the future if you continue this routine, but I would increase your training load in the future so be ready," Benimaru said, as he congratulated the four, Benimaru then left them alone as he went to the house, as he wanted to help Wolf.
