4 Path and Accident

Oni masks are artifacts that contain spirits of 10 Oni, a Japanese demon that can summon 9 tribes of Shadow Khans ninjas, the 10th mask, Tarakudo, known as the king of Shadow Khans and leader of 9 Oni generals. Tarakudo himself doesn't have a special type of ninjas but as he has the ability to summon all 9 tribes of Shadow Khans at once and enough to cover the entire world into the darkness. For now, David has only one mask, a mask of Rairakku, leader of Ninja Khan, but as long as he can collect more masks, he will be able to summon different kinds of Shadow Khans and when he gets the last mask, he will be able to largest army in the world in a blink of an eye.

Shadow Khan does not speak or need to eat because they are made out of shadow-spirits, for that reason David can understand what they saw or listen without verbal communication. This is very convenient because silent is the most important tool for a ninja, also because they are from Shadow-realms they can phase through walls and travel between shadows anywhere as long as the user gives them a destination.

12 talismans were originally the power of Shendu, a dragon/demon-sorcerer who ruled Ancient China before he got his butt kicked by Chi wizard and one of Immortal. His 12 talismans are based on the Chinese zodiac animals and they are…

Rat: Power to animate an inanimate object to life, the object can take personality, power, and traits it is based on

Ox: Power of super-strength

Tiger: Power of balance and unity which can be used for talisman combination and split person into light and dark version

Rabbit: Power of super speed which can be used by user or object/vehicle

Dragon: Power of Combustion, shoot powerful fire blast

Snake: Power of invisibility including cloths and object user touch

Horse: Power of healing/resignation from injuries and sickness including poison

Sheep: Power of astral projection, user can enter the dream or eject others into sprit form

Monkey: Power of animal shapeshifting (All animals), it can even turn an inanimate object into the shape of animal user intent to.

Rooster: Power of levitation and telekinesis which allow a user to fly and lift an object (Vader anyone??)

Dog: Power of immortality and immune from physical damage

Pig: Power of laser vision, ability to see invisible and in the dark (I don't know how this one has laser vision, explain to me if you know why). laser vision is powerful enough to melt metal plate

David wants to explore the world and interact with people of One Piece, but to do this he needs an identity. Joining the Marine of the World Government is absolute no since they turn a blind eye on injustice and action of World Nobles. Becoming or joining a pirate is attempting but it is a hassle because there is always 'That' one marine soldier who targets you as archnemesis for some reason (Such as Garp and Roger, Smoker and Luffy, and Zoro and that crazy sword girl Tashigi). 'I could join Dragon and become a member of the Revolutionary Army, that's not a bad idea since Kuma is a member and one of the Seven Warlords of the sea.' David thought of joining Revolutionary as they tend to be more of a spy organization than a full front military and his ability is more fitting to be infiltration thanks to the snake, rooster, rabbit, and sheep talismans (for once). David also has huge leverage to join since he possesses extra devil fruits to bargain with also, they have the largest information spy network which could help David to find the locations of the remaining 9 Oni masks.

Finally, David made his decision, 'I'm going to join Revolutionary and take advantage of their network, information, and training. The only problem is how to find them since they are well hidden from the world. Maybe Marine or Cipher pol has the clues to a possible rebel member or hideout.' Choosing his path, David travel to Sabaody Archipelago port to find a ship head going to Marineford, a Marine headquarters. At the port, David easily found a Navy ship heading to Marineford after eavesdropping a few Navy soldiers' conversations while using invisibility. Just as David was about to board the Navy ship, someone behind him pushed him hard and fell from the boarding plank, falling into the ocean.
