Ichigo Kurosaki is an average high school boy with a not-so-average ability to see spirits - something that hadn't affected his life much until a strange woman entered his room one day. Named Kuchiki Rukia, she's a shinigami who was sent from the spirit world to destroy a hollow - a dead-soul-turned-monster; and much to her surprise, Ichigo can see her. When the hollow suddenly attacks his family, Rukia intervenes and is injured in the process, leaving Ichigo to fight it himself. But when Rukia lends him her shinigami powers - which is forbidden - he inadvertently drains them away and has no way to return them. Now, Ichigo is a full-fledged shinigami who must juggle his studies with his newfound duty of fighting hollows; but having gained his powers through forbidden means, the spirit world isn't going to leave Ichigo alone. Ichigo and Rukia must keep their situation a secret from the other shinigami, or the consequences could be dire.
Fighting, that's what brings these two together: Fights that span most of a chapter, spilling out into others and filling up a volume with violence of a badass degree. While Bleach contains a healthy dose of fancy lad's magic and Claymore on the other hand is devoid of magic overall, both still contain the roots of good, quality sword fighting, be it magic swords or just big-ass blades.
Claymore is also the more serious of the two, firmly maintaining drama over comedy but Bleach tosses it's chips in to match it with the twists and turns of it's plot and serious moments to raise the tension. Guess it doesn't help that both worlds are a world of badass on their own, where generally non-humans combat otherworldly creatures. There are exceptions but the fantasy/supernatural reign supreme.
Following a horrific defeat at the battle of Sekigahara, two survivors, Takezo Shinmen and Matahachi Hon’iden, are deflated at having been unable to make a name for themselves and earn glory on the battlefield. But while Matahachi is anxious to go home, Takezo has vowed never to return and intends to become a vagabond, travelling the country polishing and testing his skills as a swordsman. With a beastial mercilessness when it comes to killing and a habit of cutting down all in his path, it doesn’t take long for Takezo to become a wanted fugitive. However, after being captured by a monk named Takuan and given a new lease of life, Takezo begins to live under the name of Musashi Miyamoto. Now, with a new view on life and death, Musashi continues to travel the nation challenging the most infamous fighters to achieve his goal of becoming the strongest samurai ever known.
In both manga MC deals with the sureal obstachles to reach its goal, setting is feudal in Vagabound but it's quite similar to Claymore's fantasy. The course of advancement is present in Vagabound from the starts but picks up later in Claymore. Swordfighting, violence, gore... it's all here. If you liked one you will also like the other one...
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 Zombie Powder and Claymore follow surprisingly strong fighters and have dark undertones. The hero/heroine form teams with other warriors and a civilian without any battle skills to speak of. If you appreciated the balance between protecting the weak and fighting with a hint of bloodlust that can be found in both of these titles, then you should check out the other.
