Dragon Sorcerer In One Piece

50 Miles away from Port City Urani,

David's POV

'I think I pissed her off. Oh well, it's not like I will see her again for a while anyway.' I thought as I summoned Ninja Khans to see if they completed the mission he gave them previously. With a single gesture of my hand, 3 Ninja Khans came from the shadows and kneel before me with one of them holding a black mask.

"I see that you guys complete the assignments I gave you, let me see." I took the black Oni mask from the Ninja Khan as I started to receive the information from the three ninjas.

First is the Black Oni mask: While everyone was distracted with the drama, I had one of the Ninja Khan to retrieve the mask from Cecilia without being noticed. She was more than distracted because of her siblings and their treachery, using the shadow itself, my ninjas easily stole the mask from her belt and disappeared.

Second is Drug Peclo's Ship: I knew his ship is near and need to secure before Marines or Peclo's man take it away. Using a large number of Ninja Khans, I had them search the entire city and possible area to find the ship. My reason to secure the ship is simple, the ship itself was Drug Peclo's flagship and headquarter of his entire underworld operations. This means it contains ways to contact other Emperors of Underworld or their current locations. The ship was docked 5 miles from the city and all of the crew members were taken care of (Beat up, tied up and left on Baron's mansion). Currently, the ship is on it's way to my location as Ninja Khans are sailing the ship.

Third: Find the local underworld organization and destroy them. It is a simple order but important as they are the co-conspirator and might have solid evidence to blackmail the three siblings later in the future. The task was successful as Ninja Khans eliminated the entire organization members, collected evidence and their treasures. The evidence also contains a list of corrupt Marines in Foolshout island and other officials, so it was sent to Zephyr's ship instead of Urani Marine base. For the treasures, they are transported into Drug Peclo's ship before being undocked by the Ninja Khans.

"You guys did a great job. I still have a long way to go to collect the mask but sooner or later I will collect all 10 masks. Have the Ninja Khans in the ship redirect away from the Foolshout island, I have one last business before joining you guys." After receiving my new command, three Ninja Khans disappeared into shadow and I was alone in the plain field.

"Ok, now I need to take care of Thunder Demon before leaving this island for good." This time I didn't purchase any items from the shop, unlike other times. I already have the perfect tool to counter the Thunder Demon and I have an advantage on elements since I have the power of Storm Titan devil fruit.

End of David's POV

20 Minutes Later,

David finishes his preparations and pulls out his Pan'ku box from inventory. Once he pushes the symbol of thunder (☳), the box glows green and starts to float in the air and fired the green energy to open the portal of the Netherworld. When the portal fully opened, an 18 foot tall, blue skin reptile humanoid demon stepped out with lighting surrounding him as if he was giving himself an epic entrance. The demon is fully clothed with dark blue and gold color Asian style armor unlike other demons before who wears expensive clothes or none at all.

[Tchang Zu, a Thunder Demon of the 8 Demon Sorcerers and has an explosive personality when he gives punishment to Shendu for his failure. His power allows him to control the lighting and summon storms but mainly used to generate more lighting to empower his attack. Tchang Zu can't transform into his element unlike his sister, Bai Tza, a Water Demon who can change her form into the water like logia devil fruit.]

With thunder demon summon, David activates his Storm Titan fruit power and matches the height. The demon didn't hesitate or show signs of surprise on David's appearance as he gathered his hands to create powerful lighting and blast it at David. But before the lighting could strike David, it changed its direction and struck a metal object in the ground not far away. The same metal object when David fought against Mountain Demon many years ago and now acting as a lightning rod. One of the sacred treasures from Seven Deadly Sins, Gideon.

'I knew Gideon would come in handy, I'm just glad that it works just like in the anime.' David thought as he sprinted with super speed to strike the Thunder Demon with a punch combined with Haki, an ox super strength and rooster. The three combinations are powerful enough to knock out the demon where he stood and throw him off from the ground for half a mile.

David grabs the Gideon with ease and proceeds to teleport right next to the demon to strike. Unfortunately, before the hammer could connect with its target, the demon grabbed the hammer in midair with his right hand, stopping David's attack and began to stand.

'Damn it, of course, he is tough enough to stop my weapon with one hand.' David tries to overpower the demon's strength but every time he pushes more, the demon pushes it back with his own strength. Evenly matched on strength, David uses his Earth devil fruit power to uneven the ground where the demon stood. With the ground underneath changing its shape, the demon seems to start to lose his balance for a second but to David's surprise, he maintains his balance where he stood.

Looking down, David saw how his trick didn't work, the demon was using his power to stand in the cloud where the ground used to be. 'He replaced the ground with a cloud so he can maintain his balance. Kinda reminds me of Flying Nimbus from DBZ.' Impressed with the demon's creativity, David uses Moon Demon's power to increase the gravity where the demon stands.

The sudden increase of gravity forced the Thunder Demon to let go of the weapon and retreat with lightning speed. But he wasn't fast enough as David to once again strike the demon with a hammer using the rooster talisman's telekinesis. As the hammer was coming down as the demon let go, David used the telekinesis to change the direction and made it go up instead. The result was the spectacular sight of David uppercutting the Demon's blue jaw with 2,200 pounds of solid metal warhammer.

As the demon fell in his dack, David combined his dragon and pig talisman to rost the demon. The dragon's combustion power is as powerful as Ace's fire fist while his pig's heat beam is in equal terms against Kizaru's light laser beam. After one minute of basting the demon, David stops his attack to see if his opponent is dead, after all, he still needs to use the Pan'ku box to absorb the demon's essence before absorbing it.

As the dust clears and Thunder Demon starts to appear from the glassed ground, David uses the Gideon to poke the demon's body. After two or three pokes David was certain that he defeated the demon and approached the body as he was about to pull out a Pan'ku box. Suddenly, Thunder Demon's eyes opened and grabbed David's face and warhammer, preventing him from using it against him. The demon once again stands while holding David's face while David was in panic mode as he realized that he made an amateur mistake of every cliche character in movies and tv shows. His previous victory against other demons and overpowering abilities in the One Piece world made him overconfident over the years without realizing it.

"I'm an idiot, thinking it was this easy. I got c.o.c.ky and underestimated him.' David thought as he tried to escape the demon's grasp but to his surprise, David was losing his strength. He quickly realized what was happening as his earlier mistake turned into a massive problem, the Thunder Demon was absorbing his Storm Titan's devil fruit power to recharge. If David doesn't free himself before the demon finishes recharging, he will permanently lose the devil fruit of Storm Titan.
