Onipan
Three oni-kids who, through the power of the onipan (a portmanteau of "oni" and "pantsu") become human to help fix the relationship between humans and oni. The three girls transfer into a normal Tokyo high school to aid in their task and help fix their image by revitalizing the town, sometimes jumping headfirst into school events, and other times ... becoming idols!

Otome Game Sekai Wa Mob Ni Kibishii Sekai Desu Dub
Blackmailed into playing a dating simulator set in a matriarchy, an ordinary man must put up with the unbearable and convoluted world until he clears the game. After countless days of grinding, he finally manages to beat it, but his hardcore gaming comes at a cost: extreme sleep deprivation and hunger. While heading out to the convenience store to solve one of these problems, the man tumbles down the stairs and falls unconscious, only to wake up to the worst possible realization—he has been reincarnated into the game as the mob character Leon Fou Bartfort. Now trapped in a world he despises, Leon must use his knowledge of the game to navigate through the plot safely and sustain himself in a society where the odds are heavily stacked against him.

One Piece
Gol D. Roger was known as the "Pirate King," the strongest and most infamous being to have sailed the Grand Line. The capture and execution of Roger by the World Government brought a change throughout the world. His last words before his death revealed the existence of the greatest treasure in the world, One Piece. It was this revelation that brought about the Grand Age of Pirates, men who dreamed of finding One Piece—which promises an unlimited amount of riches and fame—and quite possibly the pinnacle of glory and the title of the Pirate King. Enter Monkey D. Luffy, a 17-year-old boy who defies your standard definition of a pirate. Rather than the popular persona of a wicked, hardened, toothless pirate ransacking villages for fun, Luffy's reason for being a pirate is one of pure wonder: the thought of an exciting adventure that leads him to intriguing people and ultimately, the promised treasure. Following in the footsteps of his childhood hero, Luffy and his crew travel across the Grand Line, experiencing crazy adventures, unveiling dark mysteries and battling strong enemies, all in order to reach the most coveted of all fortunes—One Piece.
