One Piece: I Have a Fourth-Dimensional Pocket

When Xiao Kai wakes up, he finds himself in a strange place, unable to see a thing.

Just as he's worrying about what to do, the System activates, and he successfully obtains Doraemon's 4D Pocket.

From then on...

What, you can't understand the language? No problem, I've got the Translation Gummy.

What, you say you can fly? No problem, I've got the Bamboo Copter.

Come across pirates and can't beat them?

No problem, I've got an Air Pistol. And if that's not enough, I've also got an Air Cannon.

If all else fails, I'll use the Anywhere Door to drop an Earth-Destroying Bomb in your pirate hideout.

System: Ahem, ahem, well... For the sake of world peace, I really can't give you that thing.

Xiao Kai: Come on! Once the world is nuked, it'll be peaceful!!!
