The second round of the war have started. Straw Hats & Giants now have gained more energy from Kurama's chakra. Big Mom pirates start to attack again, so they rush to attack back.
While both sides start to clash, Jon is staying on the rear with Jane. Jon have a clone ready to aid his side whenever they need it. Right now, Jon is connected to all of his allies through Kurama's chakra, so he can teleport any one of them without touching them.
Right now Jon also gather energy and use it to heal himself. He also use the chakra link that connect him to the others to transfer the medical jutsu. It sound crazy, but if he can teleport those who are connected with Kyuubi's chakra, then he can also use his medical jutsu through it.
However, to heal so many people at once need massive amount of chakra. So Jon gather nature energy to supply his medical jutsu. He enter sage mode and start to heal himself & the others while still gathering more energy.
'You are so cheap.'-Kurama
'I'm not being cheap, i just didn't want to spend my chakra if it's unnecessary. Beside, nature energy make any jutsu stronger, so it's better.'-Jon
'Still being cheap.'-Kurama
'Then, did you want me to use your chakra to heal me & the others? You have massive reserve of it.'-Jon
'Hey, i'm helping you guys with this already, so use your own chakra.'-Kurama
'..... Talk to the hand!'-Jon
Jon raise his hand in front of Kurama, and make Kurama pissed, so Jon get slapped to the ground by a giant tail.
'Anyway, let me fight! You already have your fun today, let me have some fun too. You haven't let me out for a long time.'-Kurama
'Fine, just don't kill anyone!'-Jon
'Don't worry! They'll just have some big open wounds.'-Kurama grin
It didn't take long for Jon to heal himself & the others. Jon then switch with Kurama and Jane realize this. Well, it's easy because his pupil turn into Kurama's red beast eye, which only happen to Jon when he switch with Kurama.
"You, are you Kurama?"-Jane
"Yeah, it's me. I just want to have some fun, so don't mind me! You just focus on your job to shoot people."-Kurama
"Ok, have fun."-Jane
"Yeah."-Kurama
Kurama barge to the battlefield and start attacking. He make 9 tails but without turning into a giant. He often fight with his tails, so he make it now. He barge in and doesn't care of who he take as enemy, he just start blasting.
Jon tell Kurama to not kill anyone, but homies are fine. So Kurama destroy the homies, and he just swipe the humans away. Kurama didn't have much techniques, so he just strike as hard as he can.
Kurama punch, kick, scratch, or even blast his tails on enemies. His fighting style is really wild and very different from Jon's fighting style. He also didn't care much about getting hit and he doesn't use any jutsu like tailed beast bomb.
'Kid, your body is really strong now. You can be considered as the strongest human if you're in my world, in term of body of course.'-Kurama
'Really?'-Jon
'Yeah, altough it's still not on tailed beast level, but it's close. Maybe you'll reach that damn Raccoon's level in a year or two with your current growth.'-Kurama
'I'm sceptical about that, but it's good to know that i can catch up to that. How long do you think for my body to reach your level?'-Jon
'Heeh, 1000 years.'-Kurama smirk
'Fine, you don't have to tell me.'-Jon
'Well, if you can finally blast a mountain just with a punch, that's when you know you reach my body's level.'-Kurama
'Hmm, that will be difficult to reach in some years. I can do it with jutsu, but just using my hand will be hard.'-Jon
Jon know that to reach a tailed beast's physical strength is really hard. But it's not impossible, at least not in this world. The only example he know is Garp currently, who destroy a mountain just with his fist. Garp doesn't have a devil fruit, so it's his pure physical power.
'Hmm, but i don't know if Garp destroy it with one punch or multiple punch. I believe it is multiple punch though, not one. Well, i don't know that, and even if it's multiple punch, it's still impressive.'-Jon
Jon forget about that and watch on Kurama's fight. He see Kurama's fighting style and can't help but have his mouth twitching. Kurama's brutal fighting style is not a problem for Jon, but he didn't even care to dodge, that make Jon rather pissed.
'DAMN FOX, DON'T LET MY BODY HURT! You think you can do anything just because this is not your body?'-Jon pissed
'Hmm? Of course, you can heal very fast, right?'-Kurama
Jon's eyes also start to twitch and he really want to lash out, but he held himself. Jon then gather nature energy so he can heal his body faster. He can't use jutsu from his mind scape, but he can gather nature energy from there.
Kurama is blasting, and so are the Straw Hats & Giants. Kurama's chakra really energyzed them and they feel like they're in their best condition. So they start to use all of their techniques & moves that they have in their arsenal.
Kurama's chakra also protect them to some extent, so they're less worried by enemy's attacks now. Still, it doesn't mean they can let enemy's attacks hit them without trying to block or dodge. It's just a supporting aspect, so they can't rely on it.
While the others fight stronger opponents, Kurama & Jon didn't target any high ranked enemy. They just chill & destroy the lower ranked. They let other people take the high ranked enemies and enjoy destroying more people in lower rank.
"THIS IS AS FAR AS YOU GO, DEMON EYES!"-Oven
Oven suddenly appear and attack Kurama with his hot punch. Kurama jump back and the punch hit the ground, heating it and melt it like lava.
'Didn't he fight Jinbe? What happened?'-Jon
Jon take a glimpse on Jinbe through Kurama and see that he has new opponent, Perospero.
Perospero can't stay behind any longer to give command and support. He need to fight directly now, so he choose Jinbe and send Oven to Jon/Kurama. Oven has personal issues with Jon after he & his army get defeated by Jon on Cacao island.
So when Jon came back from his battle with Katakuri & Smoothie, Oven want to attack. However, Jinbe keep fighting him, so he need to face Jinbe. But then, Perospero came & face Jinbe, so he can attack Jon now.
"I will make you pay for what you've done in the past, Demon Eyes."-Oven
"Really? What make you think that i can't do the same thing that i've done before. Also, what make you think that you can defeat me when even Katakuri & Smoothie aren't capable of it?"-Kurama grin
"I'll show you what i can."-Oven grit his teeth
Jon is sighing in his mind scape. Kurama really know how to mess with people like Oven. The problem is, Kurama use Jon's body now, and Oven didn't know it, so it was like Jon said that to him. Well, not like Jon will give different answer to him.
Oven suddenly attack Kurama with a barrage of hot punch. Kurama grin and counter with the exact same move. Their punches meet each other and create quite the impact.
After some time, Oven realize a strange thing. Kurama did't flinch at all and his hand doesn't burn. Kurama is protecting his hands with his chakra, so it won't get burnt. Kurama do it by concentrating his chakra to make it like a layer of armor.
'You improvise your own type of armament haki, huh?'-Jon is impressed
'Haha, of course. I can't learn haki for some unknown reason, which i thought is because i'm made out of chakra, so i can't use different type of power. However, i sure can utilize chakra better than you, so i made my own haki.'-Kurama grin
'Ooh, that's great. Maybe i'll try it later.'-Jon
'STOP IT YOU COPY CAT! MAKE YOUR OWN TECHNIQUE AND DON'T USE MINE!'-Kurama
'Nah, this one's good.'-Jon
Kurama get pissed, and he decide to lash it out on Oven. Kurama make a big chakra hand and grab Oven's big body. Oven can't move, so he try to heat his body up and burn the hand. But it's a chakra hand, so it didn't have any sensation and can't feel hurt. Beside, Kuramanis far stronger than Oven.
Kurama just grin at Oven's useless struggle now. Then Kurama make his 9 chakra tails longer. After that, he use his chakra tails as whip and hit Oven's head continously with it. The attack speed & rate are high too.
Oven try to protect his head & upper body with haki. However, Kurama's attacks are stronger than his armament haki defense. So after many rounds of attacks, Oven finally can't take it anymore and he passed out.
Kurama drop Oven down and now everyone can see Oven's condition. He is pumelled so bad that his face is full of bruise, some of his teeths gone, and his hair's shape got destroyed. Meanwhile Kurama is smiling and laughing evilly.
"That's what you got if you overestimate yourself."-Kurama
The Straw Hats know it's Kurama and just let him be. But the enemies think it is Jon and get angry. However, even if they're angry, they didn't do anything. They're too afraid to attack Kurama, and those who can attack him are fighting other people.
The war then continue with Big Mom pirates keep being pushed back. The Straw Hats & Giants are gaining their momentum in this 2nd round, and they use it well. Furthermore, with Katakuri & Smoothie's defeat, then Oven's defeat on Jon's hands, their morale really dropped a lot.
Then after 3 hours, the war has finally finished. Big Mom pirates have finally get defeated by Straw Hats & Giants. The one who defeat Big Mom is of course, Luffy.
Altough he get some help like Kurama's chakra, or Zoro who cut Prometheus & Brook take this chance to deal a fatal blow on Prometheus as his Yomi Yomi fruit affected soul.
Nami also have rendered Big Mom's new cloud useless when she force the cloud to discharge after it turn into a rain cloud. It didn't want to eat Nami's eggball, but it still turn into raincloud on Big Mom's command, so Nami use this chance. At least Zeus in Nami's staff get satisfied by this.
On how Luffy fight with Big Mom and defeat her? Well, let's wait for Oda's reveal, shall we? You can have your war on comment section.
Anyway, in this war, only Big Mom pirates that have life casualties. None of the Straw Hats & Giants died in this war. Jon & his clones really worked hard to save people that almost get killed and send them to Chopper & Gerd on the rear line.
Now, the only thing left to do, is on how they will take care of the aftermath. The Giants really want to kill Big Mom and punish her for what she did in the past. But they let go of her children after Luffy ask them. So to show gratitude to Luffy & the Straw Hats, they let Big Mom's children live.
Jarul then step up and use his own hand to avenge his brother and restore his honor. Big Mom's children can't do anything now with their beaten up condition. At least they can take their mother's corpse to give her funeral.
Nami, Chopper, Usopp, & Jane are looking away when Jarul stab his sword on Big Mom's chest. Jon also see they are trembling in fear & shock. Jane also seem afraid, but that make Jon glad, because her emotion have developed well.
"Death will eventually come to any one of us. And for pirates like us, death might come faster. They've been prepared with this, and you should be too. If you don't want to meet it faster, grow stronger and make sure you'll live!"-Jon
