Momonga, Strawberry, and Onigumo could only stand in place. There was no room for them in this battle. Maybe they could assist Aokiji and Kizaru to some extent, but if they helped Akainu, they might accidentally get hit by Akainu's magma. Moreover, a battle of this scale wasn't something that they could help with.
"Gravity Domain: Sky Fall!"
At this time, Issho tapped the ground with his sword, increasing the gravity around him, creating a field around him to overwhelm Akainu with strong gravity. The mechanism gravity was the same as his other technique "Journey to Hell", but it was more difficult to use, because "Journey to Hell" applied gravity on the ground, while Sky Fall applied gravity on the air itself.
If it were to deal with other opponents, Journey to Hell would be enough to overwhelm most opponents, but it didn't affect Logia users that much.
Of course some hand-to-hand combat specialists, such as Kong and Garp would probably be able to move despite this overwhelming gravity.
"Is this all there is to Press-Press Fruit? There is nothing you can do here! You should've hid in Ryusu Island!" At this moment, Akainu was resisting the gravity, both of his hands had already turned into magma to attack Issho relentlessly.
His speed was somewhat reduced because of the gravitational force, but his attack was comprised of magma nonetheless. An average person would not be able to withstand his attack!
Only someone with a monstrous physique like Whitebeard could keep fighting after being hit by Akainu's attack. Moreover, at that time, Whitebeard was weakened by his illness, and he was stabbed by Squard on top of it.
Of course, when it came to physical strength, Big Mom had to be on the top of the list.
"Hehe, I have indeed cooped up in Ryusu Island for a long time, but that's not because I'm weak. In any case, I have been appointed as the leader of External Advisor by Primo-sama. If I can't even carry out my duty, that'd mean Primo-sama is mistaken in picking me!"
Issho calmly blocked "On the other hand, Sun Pirates have returned to Fish-Man Island. Is it really wise failing the mission in exchange for fighting us?"
If it were Sengoku or Aokiji, they would definitely not choose to fight with Vongola Family in this situation as the mission would fail. With the main culprit, Fisher Tiger dead, World Government should be satisfied, so there was no need to engage in this fight. But Akainu was different. He believed in Absolute Justice. Vongola Family was In front of him. How could he let go of a chance to capture or even kill criminals like them?
Even if the chance was slim, he would definitely try it!
"Cut the crap, Dark Hound!"
Akainu only had a few moves, and he didn't care as long as it did the job. Especially the Dark Hound that he was using now! Its power was much stronger than a few years ago. The current Akainu should be on equal ground with Xanxus with Sky Flame's Harmonize characteristic being set aside. Among the three future Admirals, he possessed the highest destructive power.
Even Issho didn't want to face such an attack head-on!
He immediately flew. At the same time, he controlled the gravity, making his body move in a way that was normally impossible and avoided Akainu's terrifying attack.
Following that, he enveloped his sword with Color of Arms Haki. He took advantage of his current position and swung his sword down...
"Gravity Blade: Overweight!"
"Bam!"
With the addition of gravitational force, Issho's slash was like a mountain crushing down on Akainu. Akainu himself reacted extremely quickly. He crossed his hands and forcefully blocked the Color of Arms Haki-imbued slash. However, his body suddenly fell to the ground at this moment. Both of his feet slumped to the ground. That terrifying pressure caused the bones in his entire body to scream.
However, in the instant that he blocked this attack, Akainu's entire body directly transformed into magma. After dodging the slash by separating his body into two, he rushed forward. The scorching aura instantly enveloped Issho completely.
For the record, magma's temperature was at least 100 degree celsius. Although Issho was strong, he would not be able to do anything miraculous like bathing in the magma.
If he was devoured by this lava, even if he did not die, he would still be severely injured!
"Using your Logia ability to reduce the effect of gravity? Hehe, if it was a few years ago, I might really be helpless against this. But now, it is different... "
Issho looked at the approaching magma. He knew that he had no chance to dodge, but who said that Press-Press Fruit was all he got?
"I am still inexperienced at this ability, but Primo-sama have taught me a very simple method of using it. Its name is... Harmonization!"
The moment he finished speaking, the ring in Issho's hand was lit with orange flame. After the Sky Flame lit his ring, it spread to his sword. Then, he swung his sword at the incoming magma that was going to devour him, and it was petrified at a speed visible to the naked eye.
Yes, the Dying Will Flame that Issho awakened was Sky Flame!
Even Giotto was shocked when he found out about this. After all, he was the first person that awakened Sky Flame other than Giotto and the characters unlocked by the system!
However, there seemed to be nothing wrong with Issho awakening Sky Flame. After all, he was the leader of External Advisor, so it was normal for him to have Sky Flame.
The more interesting thing was that Issho combined Sky Flame with his swordsmanship, giving him an advantage when dealing with a Logia user like Akainu.
The magma that had not been petrified retreated more than ten meters away from Issho and remorphed into Akainu. However, his expression at this moment was several times more serious than before. He had seen this kind of petrification ability when he was in the Ball Island. It was a very dangerous ability!
"So, do you still want to continue fighting, Vice Admiral Akainu?"
