Defeating A Vice Admiral

With a serious face, Comil spoke "You little punks proved to be more troublesome than I thought… Failure threatens to tarnish the esteemed reputation of the marines. Specially if the target is a rookie pirate crew like you" 

With a swift move, Comil passed through the three pirates and picked up his second katana that he dropped earlier, before he quickly turned back while swinging both weapons sideways, unleashing two powerful flying slashes.

FWOOSH!! CLANG!! With both hands, Kai tightly grasped Shichiseiken that was emanating a radiant green aura before striking back the flying slash to block it. Even though he was pushed back a little, Kai managed to stop the slash and he redirected it away. It ended up destroying dozens of trees from the forest nearby.

Without waiting for Kai to prepare for the next move, Comil coated both his katanas with Armament Haki and charged towards him again. 

"Soru!...SWOOOSH!!" With blinding speed, he closed the distance between them while thrusting his sword at Kai's heart. The latter used his Observation Haki to predict the attack and managed to block Comil's sword with his, but the sheer force behind the attack sent him crashing into a tree a few meters back.

Kai slowly got on his feet again, he was soaked in his own blood and signs of fatigue was evident in his face.

"That fucker is targeting Kai because of his injury!" Kid was pissed because of that. He started attracting various metal pieces and shaped them into several large spears, and then launched them at Comil "Punk Phalanx!!" 

FWOOSH! FWOOSH! Comil skillfully dodge them before striking back as well, he leaped in the air while raising his katanas upwards, before flying down towards Kid and slashing him across the chest, creating razor-sharp currents that cut through obstacles with surgical precision "Two Sword Style… Zenithal Zephyr Slice!"

Kid reacted by gathering the few metal pieces near him as a shield to block the attack, but Comil managed to cut through it "AGHH--COUGH!!" Kid coughed some blood as he received two large cuts across the chest, thankfully they weren't very deep since the metals reduced the force of the attack. 

"Tsk…these are gonna leave some scars" Kid wiped the blood off his mouth as he watched Bonney charging at the Vice Admiral immediately after his clash with him. She jumped at him, her hand trying to connect with Comil's body in an attempt to turn him into a little kid or an old man, but the latter saw through her and dodged her attack with grace.

He proceeded to kick her head down, smashing her head into the ground. He then tried to stab her down after that, but Bonney turned herself into a little kid and managed to avoid his blades by a few inches.

A few seconds later, Kai joined the battlefield again. A determined look in his face, he was determined to take down his enemy right here and right now "There is no room for escape, do you understand Kiddo?"

Kid smiled at that statement "I know, let's finish off this guy and leave this shithole afterwards"

"You still can move with that injury, I'm quite surprised…but don't push your luck, you'll end up dead" Comil said.

Kai didn't reply to that and only spoke to his brother "Support me with your magnetic power!" he charged at Comil using Soru afterwards and clashed swords with him. 

Clang! Clang! After exchanging a few hits, Kai took Comil by surprised and used his devil fruit power to trap him. He first generated clouds from his feet and spread them around the area without Comil noticing, and then he made them dense enough before he engulfed Comil with them starting from his legs.

Comil unleashed a few powerful sword slashes forcing Kai to jump back before he finally noticed the trap. He tried to move his legs, but he couldn't as the clouds were moving up trying to engulf his entire body. 

"What?!" Comil was shocked at that, but just as he was gonna try to free himself, Kid appeared above him. Dozens of metal pieces were flying towards his direction, and he used them to shape a gigantic hammer of metal. On top of that Kai used a thunder cloud to add a layer of lightning to it. 

"Punk Hammer!!"

BOOOOM!! With a powerful smash, Comil was crushed into the ground under the weight of the hammer. 

"Aghh--…D-Damn it…You little shits!" Comil received immense damage from that attack, but it wasn't the end. Bonney didn't give Comil the time to recover and she appeared behind him, her hand made contact with his body this time and she turned him into an old man.

It gave Kai an opportunity that he did not waste. Using Soru to propel himself towards Comil, he used the momentum and stabbed the Vice Admiral from the back. The sword pierced his upper left abdomen from the back.

The latter used Haki to remove the effect of Bonney's devil fruit ability, returning to his normal form before striking Kai with his Haki coated elbow, prompting the latter to pull out his sword and jump back.

"Now we're even, Hahaha!…Huff…Huff" Kai said with a smirk while gazing at Comil who was in pain. 

Seeing that Comil is momentarily shaken, Kid charged at him again and proceeded to throw a barrage of punches which the former easily dodged before striking back. He swung his katanas down trying to slash Kid again, but the latter grabbed both his arms stopping him. 

"You think that's enough to stop me?!" Comil was clearly going to overpower Kid easily, so the latter didn't even try to fight back. Instead, he used his magnetic power to create two metal shackles around Comil's arms before he repelled the metals back, thus sending Comil flying back as well. 

"Repel!!"

Comil was sent flying meters back in a second, and not anywhere, but towards the direction of the sea.

"Do it now, Kai!!" Kid shouted. Once Comil was above the water, Kai suddenly appeared in front him and clashed swords with him again. 

"I'm not gonna fall for a cheap trick like this!" Comil clenched his katanas and was about to strike Kai. The latter didn't flinch and only smiled in confidence. 

"I wouldn't be so sure if I were you" Kai responded. Comil's focus faltered for a second after hearing that statement, and that second was enough for Bonney to use a pistole to fire at him from the shore. Since Observation Haki needs the user to be completely calm and focused, Comil couldn't see that projectile coming and got hit in the right leg, but he wasn't hurt nor bleed at all. 

"Near-Death Experience!!" Bonney used a move where instead of getting injured, the target rapidly ages until they turn into a skeleton before immediately reverting to their initial state, which may cause psychological trauma to them.

"…?!!" It is exactly what started happening to him. Kai used that chance to strike Comil with everything he got in order to defeat him once and for all.

SWOOOSH!! With a combination of Geppo and Soru and approached the Vice Admiral mid-air while holding his sword in his right hand, he infused it with a thick layer of lightning on top of the green flames that the sword produces, and then swung his sword horizontally, creating a powerful slash attack.

"Divine Retribution!!"

Lightning! Lightning! BOOOM!! The attack was powerful enough to create a massive radiant sphere as the lightning surged out from every direction.

Comil's chest was cut open, and as he fell into the sea water the lightning burned him until he passed out. Kai's lightning attacks were more deadly in the water.

"Huff…Huff…Sayonara…" Kai smiled in satisfaction as he watched the Vice Admiral drown before he flew back to the shore again. The moment his set foot on land, he collapsed on his face "I'm at my limit"

"Me too!…" Kid also laid on his back on the ground trying to catch his breath. The only one who still had some energy left was Bonney since she didn't receive any serious injuries unlike the twins. 

Against the superior Vice Admiral Comil. Kai, Kid and Bonney emerged victorious.
