Long ago, the planet Industria used to be peacefully ruled by the royal family. But when an alien race invaded, the world delved into a war that's raged for the past 50 years, with no signs of stopping. Astro is an orphan who survives on the streets and does what he can to feed other children like him. But when his lookalike, the prince Bulge himself, suddenly appears, Astro's life is turned upside down! The selfish noble wishes to love a carefree life of indulgence, and he wants Astro to take his place. And after the prince is then suddenly assassinated, Astro is whisked away to the palace for his new life of politics and luxury. How will this streetwise boy handle his new role on the throne, and his new responsibility to put a stop to this decades-long war?
Haru Glory lives peacefully on Garage Island with his sister. One day, Haru fishes a strange dog-like creature named Plue out of the ocean, and soon after meets its master, an old man named Shiba. With this man comes terrible news: the world is in peril, for the evil organization Demon Card is attempting to conquer it with power-giving stones known as Dark Bring. To combat this threat Shiba has spent much of his life fighting back with Rave, a Holy Bring; and the Ten Commandments, a sword it powers. When members of Demon Card arrive at the island, Shiba discovers that Rave and the Ten Commandments will now only respond to Haru, making the young boy the new Rave Master. Armed with newfound power, Haru and Plue set forth to put a stop to Demon Card.
Rave and Sensei no Bulge don't have a similar plot at all, but have an extremely familiar Shounen Jump feel. Lots of interesting creatures/monsters, a healthy mix of action and comedy, fantastical powers, and unique worlds and cities. Rave is definitely the better of the two, but fans of one should likely enjoy the other.
In the world there are thirteen "rings of death" which, once collected, can be used to create "Zombie Powder": an elixir capable of granting immortality and restoring life to the dead. Many have tried to collect these dangerous rings which devour their wearers - and all have failed. John Elwood Shepherd is a young pickpocket who lives in one of the many small towns surrounded by the wasteland. When he meets Akatubi Gamma, a wanted criminal on a hunt for the rings; and his mysterious partner C.T. Smith, a highly-talented gunman; he is drawn into following the two in the hopes of saving his sister and having an adventure along the way!
Both of these feel like traditional shonen manga: An unlikely hero, a cast of unique characters, adventure, and tons of action. Both of these series are also only a few volumes long and have open endings. If you liked the type of action in one, you'd definitely enjoy the other.
